    #4 or #1 in a 12 please! I am trying to live eco-friendly and this is a big change i might be able to make to lower my carbon footprint!

  2. Danielle Bhagat July 27, 2020 at 10:24 am

    Would love to trial the classic full brief overnight in a size 12 would love to trial and see the benefit of a reusable menstral product.

  3. Donna Bell July 24, 2020 at 8:53 pm

    A) 8
    B) Size 12
    C) I have been seeing ads for different types of period underwear everywhere recently which is fantastic. I’m a little bit scared at the thought of using them and there being a leak but I’m sure they’ve tested them thoroughly and they seem to have a large number of satisfied customers.

    The thing I actually love the most about these (apart from them being great for the planet) is that my daughter will have the option of wearing these when she eventually gets her period, it will be a much nicer transition than using sanitary products. I’d definitely love to try them out and to also show my daughter this wonderful option.

  4. Hollie July 19, 2020 at 10:07 pm

    I have always wanted to try these products, both for playing a part in sustainability and decreasing items that go to landfill. Would love to try #15 active brief in a size 8 for workouts and walking.

  5. Jen Wiig July 17, 2020 at 5:05 pm

    Would love to try #5 full brief heavy flow in size 20 please.i had applied via kidspot for active wear ones but I’ve since been rushed into hospital and having gall bladder removed so active wear is now out of the question
    I’d love to try these because I’ve always wanted to know what period underwear would be like, I currently only use sanitary pads so anything that’s user friendly like them without the bunching up and discomfort and more environmentally friendly Im keen on.

  6. Wenyu Liang July 17, 2020 at 4:15 pm

    I always worry about leaking during my period so would definitely want to try this product to see if it can give me a release! I would like to try Seamfree Full Brief – Heavy-overnight – Sizes 12 please!

  7. Jaimee Cooper July 17, 2020 at 3:43 pm

    Seamfree Bikini – Moderate-heavy – Size 12/M

    I’d love to try these please. I occasionally use a cup as I’d like to use watesfree options but it’s not always my preferred choice, especially on lighter days and I’m tired of using pads and tampons (and dislike the waste that comes from using them). I have been thinking about trying these period underwear for a while now but have been unsure about purchasing some and this is the perfect opportunity to give them a go. Thanks.

  8. Rochelle Ganderton July 17, 2020 at 8:49 am

    4.Seamfree Full Brief – Moderate-heavy – Sizes 8-26 size 16 or L.

    I am very interested in sustainable period products. I have never tried period undies that you wear during the day and carry on with life! I do use a cup which is great but some days I am not keen on dealing with the constant need to empty etc.

    My daughter is 13 and uses pads and I would dearly like to get her using sustainable products but I need to know I can use them without hassle before trying to convince her that it will work and I had zero issues with it etc.

  9. Anita Erceg July 16, 2020 at 6:19 pm

    I would love to trial #6, the classic bikini. After an endometrial ablation my periods are much lighter then they were but are irregular so i am never sure when they will start. This product could give me back so much of my confidence, and i could go out without having to think ahead to where the closest bathroom is. I am size 14

  10. Serena Kelly July 16, 2020 at 4:13 pm

    Hi, I would absolutely love the chance to try out some Modibodi period and leak-proof underwear! I have not tried Modibodi products before and I would love to give them a try as I have already tried out two other different brand of period-proof underwear and both of these other brands have leaked (despite them having a leak-proof guarantee!) when I used them. I am desperately tryng to find a brand of period proof underwear that actually does what they say they will do as I would love to use them to manage my periods in a sustainable way. If I was chosen to review this product then I would be able to compare it to other similar products that I have tried previously and see how they differ and most importantly see how well they work. I would love the opportunity to try out some Modibodi products in size 14/L in either of the styles #5, #8 or #10. Regards, Serena

  11. Nicole Lee July 16, 2020 at 3:41 pm

    Hi would love to try No11 size 16 . I am in peri menopause and my periods are all over the place. I find
    Pads at night just to bulky and been wanting to try period pants for a while . Thank you

  12. Steph Mason July 16, 2020 at 2:45 pm

    Would love to try #11 in size 14. I have a very heavy period and struggle to find anything comfortable and leak proof for overnights!

  13. Joekie Potgieter July 16, 2020 at 11:05 am

    I’d love to try Classic Boyshort – Heavy-overnight – Sizes 16. I use a cup but would feel better to have extra protection or be able to sleep without a cup.

  14. Felicity Smith July 16, 2020 at 10:35 am

    I would love to trial a product to make me feel better when I run during my periods. I get anxiety about light leaking and would love to see if these products are as comfortable as advertised in larger sizes. It would be great as I would love a more sustainable solution to bulky pads.

    Active Brief – Light-Moderate – Size 18

  15. Sharon Goldsbro July 16, 2020 at 9:50 am

    Hi! I would love to give the Classic Bikini in size 14 a try – more to the point it would be for Miss 11. My daughter has just started her periods in the last 3 months and is still getting the hang of (and hating) sanitary pads….not to mention her rolling around at night in bed and things getting messy etc…Tampons are not in her vocabulary right now. These sound amazing!

  16. rachael kennedy July 16, 2020 at 8:36 am

    #1 #3 or #8 please in a 16 my sister would love to trial this as shes had a lot of probs with esp heavy periods and fiberoids and heavy flows (shes had a few kids and is 36)
    she would be the perfect one for a trial

  17. Vikki Sainsbury July 16, 2020 at 8:31 am

    I have heard so much about Modibodi underwear! I am turning 50 next year and no sign of menopause! My periods have always been yuk but getting worse as I age (heavier, longer duration etc). I currently use organic pads and tampons which is actually costing a bit and being in 1 wage with a 7 year old is difficult. I’ve also been diagnosed with a large intra-utarine fibroid which causes even more period problems . I would so love to join this trial team and think #8 Classic bikini heavy-overnight in size 12 would work best for me thanks!!

  18. Charmaine Willis-Croft July 16, 2020 at 6:52 am

    I’d love to try #15 in a size 14 please. I’m a Mum of 5 and as I’ve got older I’ve noticed issues with leaks, especially during exercise. This would be a lifesaver and helpful for light period days too.

  19. Andrea Couldrey July 15, 2020 at 11:15 pm

    Thanks for the great trial – I would love to try the Active running shorts (size 14) or the Active Brief – Moisture Wicking (size 14). Working outdoors on the farm in all sorts of weather can get uncomfortable at times and sweating can be a major problem. I would love to see how these go. Thanks

  20. palindrome July 15, 2020 at 10:59 pm

    Pretty please Her World! I would love to try #10 Classic Full Brief – heavy overnight in a size 8. Or #5 also looks great! :

    I have very heavy periods so would be able to give an honest review on how effective these are.
    Would also love to try Modibodi as I’ve been looking into how I can manage my periods in an environmentally friendly and responsible way 🙂

  21. Fiona Elliott July 15, 2020 at 10:54 pm

    Ooh yes please trialing this type of product would be amazing. Am so over having heavy periods and always soaking many pairs of underwear &/or active-wear. Maybe trialing the Classic bikini – heavy/overnight size 12 would be a good choice to try. Thank you.

  22. AnKi July 15, 2020 at 10:28 pm

    #10 Classic Full Brief – Heavy-overnight please. Size 18.
    I’ve used cloth pads for over a year now and love my period being plastic free. I’ve never tried period undies but have always been curious if they would be even better than my current choice. They just seem like they’d be so easy to use. Heavy flow pads can be uncomfortable and move around during sleep, it would be cool to trial this option and see if it helped with some of those issues.

  23. Elisha Gilmore July 15, 2020 at 10:22 pm

    5. Seamfree Full Brief – Heavy-overnight – Size 16 – Super keen to try something new, Thanks!

  24. Nilofa Faruk July 15, 2020 at 10:03 pm

    I would like to trial number 16 in size 10 please. I sometimes leak on the sides. Would be nice to trial to see it will help.

  25. Kaza July 15, 2020 at 10:01 pm

    Classic bikini size 12 please love to trial the moisture wicking ones,after a work out to see how good they are .

  26. Ruzan Forrest July 15, 2020 at 9:41 pm

    I would love Number 5 in Size S please. I wanted to try period underwears for a long time for many reasons. First I hate feeling of pads and tampons, second I always forget to buy them and it is so annoying to use clothes instead, I spend lots of money on pads and at the end they just so bad for littering environment. These under wears look so comfy and stylish, will make period days so much nicer and comfortable.

  27. Helena Campbell July 15, 2020 at 9:28 pm

    Number 10, size 10 be perfect to try now my period is back after baby – great for overnights

  28. Rochelle Vickers July 15, 2020 at 8:54 pm

    Yes please, Her World!  I would really love to trial Modibodi style #3 in size 14.  I’ve already made the switch to many other reusable products, and I’ve been looking into period underwear as an alternative to reusable pads, but have found the range out there a bit overwhelming.  These look super comfy and so many styles to choose from.  So pleased they are becoming much more mainstream now.  With support from me, I’m hopeful my two young daughters will be able to avoid single-use menstrual products right from the start too.  Perfect timing for Plastic-free July! 

  29. Trudy Longson July 15, 2020 at 8:02 pm

    Hi. I would love to try the classic full brief , light moderate, size 18. I am 69 yrs old and get bladder leakage when I sneeze and cough. These sound just what the Dr ordered. Sound absolutely fabulous

    • Trudy Longson July 15, 2020 at 8:06 pm

      Oops. The classic full brief I requested trying is #9 Light moderate. Size 18 please. I am 69 yrs old and get bladder leakage when I cough & sneeze. These sound just what the Dr ordered. Sound absolutely fabulous. Thanks for the chance

  30. Pene Hallett July 15, 2020 at 8:01 pm

    I would love to trial #10 size 12 please. I have always wanted to try period panties but haven’t had the courage to. I have heavy periods and need to use maternity pads and would love to trial the period undies while I’m running, instead of having to wear bulky pads in my running tights. Would love to review these for other running mums.

  31. Tracy Dorset July 15, 2020 at 7:57 pm

    Oh my goodness I have been dying to try these underwear’s for soooo long!! The reviews are pretty good but I have a heavy period so I wasn’t too sure on spending the money on them … I would love to try #1 in size 8 and would be so grateful to be given the chance to give a good honest review for other woman and mums out there that have also contemplated buying these awesome sounding undies! Thank you Kidspot for another amazing trial!! Xx

  32. Maur July 15, 2020 at 7:48 pm

    Would love to trial #5 in size 18
    i suffer from super heavy periods since my last baby (now 3yrs old). Double protection with tampons and pads (super) and i still have to go to the bathroom every hour – hr 1/2. Would just like something to make life easier and normal whilst on this week. Have tried a reuseable brand but it didn’t keep me dry. Will keep trying to find one as i love the environmentally friendly concept.

  33. maureen gray July 15, 2020 at 7:42 pm

    Would love to trial #5

  34. Hannah Ross-Taylor July 15, 2020 at 7:41 pm

    Id love to try the Active Running Shorts in Size 8 please. As an active gym goer 5 days a week, this would be a lifesaver for those sometimes akward times and hopefully ease my mind. Would love to see if they really work! I hope so.

  35. Mummyof3 July 15, 2020 at 7:39 pm

    Would love to try #3 size 14. I’m always trying to find new ways to be more environmentally friendly and already use a cup. Would love to try these as using reusable pads didn’t work for me as they kept slipping around. My preteen daughter would no doubt find these perfect when she starts her period so trying some myself will mean I’m better prepared to help her learn more when the time comes.

  36. Sandra Poff July 15, 2020 at 7:28 pm

    #14 size 18 light bl

  37. Heather Dillon July 15, 2020 at 7:24 pm

    Would love to trial these. Every since my 2 children, I’ve had really heavy periods, and I also switched to using a MoonCup as disposable products with heavy periods was expensive. The first two days are so heavy that the cup can’t always keep up, and so I get leaks when full – and if I exercise it’s impossible for my cup to cope. It gets messy. I am in tears those 2 -3 days with the amount of clothing/underwear changes I need (and pads just don’t help the situation) – and when I’m in the office I’m stressed about it. I also prefer not to use the cup overnight – so these Modibodi underwear sound like they would be perfect for me for day and night requirements and might make life a bit happier during my period! Would like to try Seamfree Full Brief – Moderate-heavy – Size 8 if I’m lucky enough to be chosen.

  38. Victoria De Las casas July 15, 2020 at 7:24 pm

    I have just been looking into these this week and have read great reviews so would love to trial for myself
    Happy to trial any
    But#1 #5 or #8 in a size 12 would be great
    What a great idea they are

  39. Megan Vajani July 15, 2020 at 7:23 pm

    Number 10 in a size 12 please!
    I have heavy periods so would absolutely love to take part in this trial!
    Thanks for the opportunity, Megan 🙂

  40. Kylie July 15, 2020 at 7:21 pm

    I would love to trial the Active Brief #15 in size 12. I have started to run to help improve my mental health, but I notice when running while wearing a cup I feel like I need to pee the whole time! The moisture wicking would be amazing also, as sweating comes with running but also the meds that I’m on make me even sweatier and I get very self conscious that it looks like I wet myself!

    • Karyn Churcher July 15, 2020 at 9:40 pm

      I would love to trial the Boyshort in a 20 please I have heard so much about these and my doctor recommended trying them as i have allergies to so many things now as a mum to four girls i think this may be a great long term thing for us all thanks

  41. Angela Pratt July 15, 2020 at 7:21 pm

    I love to trial number 13 size L (14). I can’t use tampons anymore I have a bad reaction to them now. I use a cup but find on the 3 or 4th day of my period I’m very light so end up using liners or pads. Would love an alternative.

  42. Aimee Torrie July 15, 2020 at 6:49 pm

    Number 4 size be awesome just had baby number 2 3 months ago and have had a tough time with retrained palcenta twice all up had 12cm left behind and almost died from blood poisoning but am slowly on the med so this would make my day.

  43. Mary Jo Chase July 15, 2020 at 6:20 pm

    I’d like to trial number 5, size 8 as I hate leaky, bulky pads overnight which lead to laundry.

  44. Tracey Bartolec July 15, 2020 at 6:11 pm

    I’d love to trial number 3 in size 10 please. Since doing IVF and having my miracle baby I now experience extremely heavy periods and I’m mindful of the waste disposables create – so trialling these as an alternative would be great!

    • Rebekah Taylor July 15, 2020 at 7:22 pm

      Number 3 size 12. To help with menopausal leaking in a sustainable way.

  45. Shayla McDonald July 15, 2020 at 2:11 pm

    I am interested in sustainable products which help to decrease waste going to landfill. I have never tried period pants and would love the opportunity.
    I would be interested in size 16 boyshorts (no.11)
    Thank you.
