The Bare SB System Mid Layer Boot Liner is a stretchy, breathable underlayer designed for scuba and diving gear. Crafted from polyester/spandex anti-microbial fleece and featuring Polartec Power Stretch technology, it provides compression-resistant comfort that fits neatly under a drysuit for long underwater sessions.

As a moisture-management mid layer, it moves moisture away from the skin in a second-stage process and dries quickly to keep you dry and comfortable. Anti-microbial properties help inhibit bacterial growth for odor control, while flatseam stitching throughout reduces chafing during extended dives.
