from 24 reviewsThe most comfortable briefs I have ever worn. Really like them

The Modal Boxer Briefs from NinNin are AWESOME! Super comfortable and breathable. The ultra-soft modal fabric feels like silk against the skin, but has enough grip not to slide around, and they keep me cool all day long. Whether I’m at the gym or just going about my day, these boxer briefs provide the perfect fit and stretch. Highly recommend to anyone looking for next-level comfort and style!

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.

Excellent product made with durable light materials. Feels like Im wearing nothing when sleeping.

Wearing briefs made from modal material has been a game-changer for me—they’re incredibly soft, breathable, and provide all-day comfort. I highly recommend them for anyone looking to upgrade their everyday essentials.

The look and feel of these inu boxers are fantastic! Almost feels like you're not wearing anything!

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!

INU- Boxer brief is a solid choice for comfort and style. The soft modal fabric feels light on the skin, offering a snug, supportive fit that stays in place throughout the day. The premium quality and timeless design make them worth the purchase. Ideal for everyday wear or special occasions, these boxer briefs deliver on both performance and style. Definitely recommended!

If you're looking for a comfortable, cool, and soft boxer that hugs your family jewels just right (not too tight, not too loose), these are perfect! The fabric is incredibly smooth and lightweight.
They're also great for running and cardio sessions, as they keep everything in place and cool with their mesh and anti-microbial fabric.
I also appreciate that there are no tags to scratch or cause itchiness.

Great fit and very stretchy. Feels like you're not wearing anything. Great for exercise. Also very breathable which helps keep the goods dry!

They are snug and keep my undercarriage moisture free. Almost feels like nothing is there! Love my ninja suit!

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!

Really like these boxers, I'm usually pretty picky about underwear but the modal is super soft and comfortable to wear all day. Can definitely recommend!

This is my first time wearing briefs from modal material. Super comfortable and highly recommend

This is a very comfortable pair of boxers! The sizing was pretty accurate when I tried the M size which fit 30-33” waist. It also fits very well to my body and I like how the boxers don’t clump or get tight. It breathes very well and it feels dry around my parts. Overall I think this is a fantastic product which I would get again.
