Packaging Disclaimer
We tried to do better for the planet, but this one didn't work out. To reduce our environmental impact, we packed select underwear styles in this collection in compostable bags. Some of these bags broke down sooner than we expected, so yours may arrive torn or damaged. We're sorry about that.

The underwear inside is brand new and unworn. If it's a gift, the bag may not be gift-ready. All other C-IN2 products are unaffected.

Brief style underwear
Low-rise, sits below the natural waistline

Model's height is 6'1"/185 cm, and he is wearing size M.

    Very comfortable for all day wear

    The sports brief is very comfortable, and the slight low-rise cut looks and feels great. There's enough space in the pouch to keep everything in place without being too tight. It does run small -- my size is usually Small, but Medium fits the best.

    Great briefs. Theyre very comfortable

    Great briefs. Theyre very comfortable and you dont even feel them. Not constricting at all for wide thighs.
