The most comfortable briefs I have ever worn. Really like them
Great product after a handful of washes. Still feels the same and very airy to protect the nuggets. Thank you for creating a cool brand.
Ordered the 3 pack and am very happy. I've had modal T-shirts, but never had modal underwear. I like modal since it's very soft material and these underwear do not disappoint!
Great fit and very stretchy. Feels like you're not wearing anything. Great for exercise. Also very breathable which helps keep the goods dry!
Review:
The INU Boxer Briefs are fantastic—super comfortable with the perfect amount of stretch. The ultra-soft modal fabric feels amazing, and the cooling feature keeps you dry all day. Plus, the packaging is really sleek, and the free sticker was such a nice touch. Highly recommend giving them a try!
