Customer photo review of Sky – Period Underwear – Ultra-Breathable

I just tried my new period underwear and I'm super happy with it! It's very pleasant to wear (even during this heat wave!) — you feel dry without feeling like you have any protection on. Besides being breathable, it's very well cut. I was a little afraid to try period underwear, but now I'm convinced — so much so that I just ordered a period swimsuit! The order and delivery went really smoothly.... I recommend it!👌

Customer photo review of Sky – Period Underwear – Ultra-Breathable

Bought for my daughter, who is thrilled! One pair lasted a whole night, another a whole day. She has a medium/heavy flow, so that's a great result! After going through the machine, they came out spotless. Same goes for comfort. My daughter feels great in them!

Customer photo review of Sky – Period Underwear – Ultra-Breathable

I've already tried several models, but this one is truly amazing. Extremely comfortable and well-cut. The size guide advised me really well. I recommend it without hesitation.

Sky – Period Underwear – Ultra-Breathable

I just used my period underwear, and it's perfect! It feels like wearing totally normal underwear, and on top of that it's perfect in hot weather — I think it'll be ideal for sports sessions too. I was a little hesitant about period underwear, but now I'm convinced!👌

Sky – Period Underwear – Ultra-Breathable

After exchanging a size S for an M (even though I had measured my hips carefully), I tested the Sky style for nighttime only. I had no leaks (I don't lose much at night). This is the first period underwear model I've tried, and I find it fairly breathable (less than cotton underwear, for sure!). I'm satisfied and won't hesitate to recommend it.

Sky – Period Underwear – Ultra-Breathable

I was surprised to feel pretty comfortable in this period underwear during my first test at home. We'll see how it goes at work (I work at a daycare).

Sky – Period Underwear – Ultra-Breathable

I'm thrilled with my purchase — the breathable period underwear is really very pleasant to wear and genuinely suited to "plus-size" body types

Sky – Period Underwear – Ultra-Breathable

I'm sold on this period underwear — it's super pleasant to wear compared to other brands. The size matches the measurements listed on the site well. Everything was perfect: communication, delivery, quality. I love supporting this brand too!

Sky – Period Underwear – Ultra-Breathable

Perfect fit, no risk of leaks, my daughter is thrilled about this step into adulthood — she feels like she isn't even wearing them!!

Sky – Period Underwear – Ultra-Breathable

Ultra comfortable period underwear. Lightweight and really pleasant to wear. Too bad the liner isn't removable. I haven't had them long enough to judge the durability, but it seems good.

Sky – Period Underwear – Ultra-Breathable

Period underwear that stays in place well. The breathable fabric is really pleasant. The protection is good: neither too thick nor too thin.
