Private: Breathable 4-Way Flex Low Rise Sport Brief, Solids


Gray; Maroon; Midnight Blue; Moss Green



This Breathable 4-Way Flex Bamboo Silk Low Rise Sport Brief is easy feeling, easy moving. Bamboo Silk is a Rayon made from Bamboo with 4-way stretch that is off the charts soft and very stretchy all ways. This allows it to hug you comfortably all around. Cotton has only a 2-way stretch, so it doesn’t move as easily with you, plus Bamboo Silk is breathable and quicker-drying than cotton, and that keeps you cooler and dryer. Bamboo Silk is also naturally anti-bacterial, which is another major plus of this great fabric. The Lower Rise of this Brief means that the waistband sits a bit lower on the waist and the coverage of the Brief is a bit sleeker.

Bamboo is a type of Rayon, and the products at BriefBuy lean toward the smooth, sleek feel. Like Modal, Bamboo is ultra-soft and it breathes, so you stay cool. It wicks moisture away from your skin and is quicker drying so you stay dry and comfortable. It’s 4-way stretch (vs. just the 2-way stretch of Cotton) moves any which way with you for all around comfort. Some of our Bamboo products are crafted in a very thin, lightweight fabric which make them ultra air permeating and breathable. Additionally, Bamboo is naturally hypoallergenic, anti-bacterial and odor-resistant. Bamboo is pricier than Cotton too, but we’ve got good deals making this luxurious material affordable for everyday wear
