Super comfortable and absorbent

[This review was collected as part of a promotion.] Ideal to use during the night since it absorbs very well, and you can sleep relaxed, without fear of spills. The soft, breathable fabric and designed for worry-free sleep. They are suitable for washing machine and dryer. The size is perfect, and I can't talk to you about durability, since I could only use it in a single period
Good!!

[This review was collected as part of a promotion.] Luckily haven't had to use yet since i usually don't get them but will be perfect for my light flow. Seems thick but won't be visible under pants, and tried them on and are super comfy! Seem great quality wise.
Comfort and function all in one!

[This review was collected as part of a promotion.] These are super comfy and have a bit of built-in compression. They fit like a very short pair of bike shorts and feel like excellent quality materials and construction. I personally wear them overnight, as I wonder if the lines where the shorts end on my thighs would be visible in pants during the day. I prefer a brief cut for daytime. Unfortunately I am a very hot sleeper and just by the nature of these having a large absorbency area, I did find myself quite sweaty on a few occasions. I still find their comfort and quality to be worth it though. Honestly I’m sweaty no matter what I wear! I really like this brand I general so definitely recommend!
Great for heavy periods!

[This review was collected as part of a promotion.] I received these to review, had I bought them I might have gotten a size up. I was afraid of leakage, so I think they are true to size. They fit more like biker shorts, so it’s nice being able to wear these overnight. I wish the waistband was slightly thicker, but they’re comfortable enough. They did not come with wash instructions, so that needs to be researched online, I wish the tag explained how. Overall I like that these are a more eco-friendly product.
Great for overnight

[This review was collected as part of a promotion.] These definitely take some getting used to! I’ve always used tampons to pads but wanted to switch to these for overnight. I really like the material and how thick it feels. The high waist definitely feels nice when you’re bloated and cramping. And they’re true to size.

[This review was collected as part of a promotion.] These shorts are a super interesting concept. I was very hesitant to try them out but when I did I had no leaking and no mess. Truly! Would definitely recommend to anyone on the fence.

[This review was collected as part of a promotion.] While these period proof underwear work great, they are a little bulky but still remain comfortable for night time wear. They are easy to clean and seem to hold up well.
Comfort!

[This review was collected as part of a promotion.] Wasn't able to get a pic of me wearing these. I'm not a big fan of boy shorts but these were extremely comfortable to wear. Just wish the waist band was a bit thicker but other then that amazing. Kept me protected from making a mess all night...wish I had some more and had these many years ago. A very breathable,light,durable and easy to care for product.
Reliable period underwear.

[This review was collected as part of a promotion.] These are really comfortable. Underwear I would wear them by themselves not with any pants mostly to sleep. They kept well throughout the night didn’t have to change I would get your normal underwear size

[This review was collected as part of a promotion.] I received this product in exchange for my honest review. I am usually between a size medium and large. And the medium fits perfectly. They are comfortable and breathable. But does not leak.
Well made and comfortable

[This review was collected as part of a promotion.] I'm genuinely impressed by the quality of these period boy shorts. They're comfortable and fit pretty true to size. The actual material feels durable and holds up, the pad area in the crotch actually feels like a proper disposable pad. Thick enough that it could handle a normal flow.

[This review was collected as part of a promotion.] I’m 5’1”, 105lbs and the XS fit just right. I have never used this type of product before, but it’s not something I’ll be using regularly. If you prefer pads over tampons, I think you’d be more inclined to use.
Leak free, but sweaty

[This review was collected as part of a promotion.] I have tried period underwear before but never any this full coverage. I like how they feel protective from any leaks around the middle and especially up the back. I didnt have any issues with shifting or leaks during the night. I have a moderate flow and everything was contained. The only downside is I did find these undies to be a little sweaty. It states the fabric is wicking, but the polyester/platic-y feeling fabric was not the best for hot sleepers.

[This review was collected as part of a promotion.] I really like how this period product fits—it feels just right, not too tight or loose. The sizing is exactly as described. I was surprised by how well it held up after using it several times during my menstrual days. It’s super comfortable and didn’t irritate my skin at all. Plus, it absorbs really well, so I feel secure and comfortable all day long.
Nice addition to period routine

[This review was collected as part of a promotion.] This was crazy timing... I just switched to Period underwear about 2 months ago. I have been dealing with pads not fitting properly and I don't like tampons anymore since my 2 kids were born. They don't fit right and are constantly leaking. This came to me and I was a little hesitant on the size but they fit perfectly and are very comfortable! Leak proof, no issues on worrying about leakage. Threw them in the wash and they came clean.
