The Reusable Period Undies from U By Kotex in the Ruby Red are a game changer! This was the first ever reusable period product I had ever used, the underwear itself is so comfortable to wear and the colour is super cute. The built in “pad” doesn’t feel any different to wearing regular underwear. It doesn’t feel nor look bulky when you wear them. In my time of testing the product I didn’t have any leakages which was amazing. I thought reusable period undies would make the odours you get when you have a period smell a lot worse than a regular pad buy drawing it out more, but there was no trace of an odour at all which is a really big plus with this product. The only small issue I had with using this product was that I had to hand wash it ever time after use even ... MoreThe Reusable Period Undies from U By Kotex in the Ruby Red are a game changer!

I wash my clothes in warm/hot water, the directions for washing the underwear is to wash them in cold water. Overall I really recommend people to give this amazing sustainable product a go!

These underwear are the best period underwear I've tried. I get super heavy periods and these are so absorbent I lasted the night wearing them with no spillage. The fit is amazing, super highwaisted that covers my bloated period belly. Very comfortable and I like that they are a very bright red colour. Most period underwear are black but these stand out in my underwear drawer so I know exactly where they are when I need them. I'm definitely going to purchase some more, can't recommend enough

U By Kotex Thinx Reusable period High Waisted Briefs are comfortable to wear and it feels just like you are wearing regular underwear. The style and cut of these high waisted briefs make the undies feel comfortable and secure when worn. The material of the undies is soft and the padding provided in the undies provides great absorption. I experienced no leaks while using these undies. They provided excellent protection. Perfect for overnight. I also love that these are an environmental friendly product. Highly recommend.

I appreciate the idea of reusable period products, however, I find it difficult to find ones that are suitable for my periods. These high waisted reusable period underwear were super comfortable, but I could not use them for the first few days of my period without leakages occurring. Padding is provided around the central area of the underwear, but not anywhere towards the back where period blood would flow when sitting or walking. I think that I would have enjoyed this pair of period underwear more if I had a lighter period.
Horrendous 'high waisted' grandma undies that pulled up higher than my belly button. When doing the qualifier for this trial I most definitely would have selected 'bikini' because I do not like nor wear massive bog catchers such as these. That nightmare time of the month, when I'm at my most feral, it was awful to have to trial these gigantic lady-nappies. They're a great concept and a beautiful colour in Ruby Red and perhaps would have been a better experience had they been bikini & not massive undies I avoid like the plague. There's no need for the blood drop symbols printed on the front, with the built in pad you definitely know they're not for every day. As practical as having a black gusset is with this being a reusable product and blood staining terribly.....I ... MoreHorrendous 'high waisted' grandma undies that pulled up higher than my belly button.

Pros:- I love the colour!- Fit is very true to size- The black absorbent section is easy to wash- Flat wide waistband- Relatively breathable- No leaksCons:- The body fabric is very thin, which makes me dubious as to the durability.- Although there was no typical VPL when wearing these, the outline of the absorbent section was visible through pants (tested in both jeans and work trousers) due to the contrast of fabric thickness between the thick absorbent section and the very thin body fabric. This was visible predominantly from behind, and made them awkward to wear. They would have an extra star if the body fabric was a bit thicker which would likely resolve this issue.- I understand it's personal preference, however they would be great if they ... MorePros:- I love the colour!- Fit is very true to size- The black absorbent section is easy to wash- Flat wide waistband- Relatively breathable- No leaksCons:- The body fabric is very thin, which makes me dubious as to the durability.- Although there was no typical VPL when wearing these, the outline of the absorbent section was visible through pants (tested in both jeans and work trousers) due to the contrast of fabric thickness between the thick absorbent section and the very thin body fabric.

The last thing I want when I have cramps and feel bloated is a waistband around my stomach.Overall, they don't leak and are comfortable enough to wear.Thanks!
Overall, I loved using these period undies! They were super comfortable, you can fold the top if they are too high and they still are comfortable.I am a light bleeder so these didn’t have any trouble with absorbing everything.They are a little like wearing a built in pad. So if you don’t use pads, I wouldn’t recommend these ones.Otherwise, the are definitely a life changer. And I LOVE the fact there is no environmental waste. Woo, Go U!!
Y BY KOTEX Reusable Period Undies were extremely comfortable to wear, especially compared to a pad which can move around and be quite uncomfortable. It didn't feel like there was anything down there or show a bump when wearing tight clothing, which i find can happen when wearing a pad. I have quite a heavy flow where i usually change out a pad every 2-4 hours as it starts to leak. With these undies i didn't have to worry about leaks as often. The biggest plus to this product is it is reusable and you just wash it and wear it again. I highly recommend this product.
Such a great and eco friendly menstrual product. I would definitely recommend this product. The only issue I had was a little leaking into the seams. However in saying that I did find them a great alternative instead of liners and pads for extra protection to combat that issue, I would definitely continue to use this product for that purpose in place of pads and liners. II found these period undies to feel as if I was wearing regular underwear there were very comfy and not at all bulky.Super easy to wear, wash and reuse.
I was VERY excited to trial the U BY KOTEX Reusable Period Undies (High Waisted - Ruby Red), as I have never really tried out reusable period products before. I was nervous, but the underwear were perfect in every way! They were comfortable (not too tight and didn't dig into my legs/waist), easy to rinse out and wash, and didn't leak. I have a light/medium period flow, so they were perfect. You can easily use a pad/tampon along with the underwear, and still be discrete! The fabric is nice and thick. The only reason I gave this product 4-stars is that I wasn't a big fan of the burgandy red colour of the underwear. I found that it was difficult to tell if you had leaked onto the undies. Would have been 5/5 starts if the colour was different, but apart from that, they ... MoreI was VERY excited to trial the U BY KOTEX Reusable Period Undies (High Waisted - Ruby Red), as I have never really tried out reusable period products before.

Perfect for all ages!
