Undersuit Top Base Layer Black-White XXXL Mares 4121733XL

Description:

The Mares Base Layer Undersuit - Shirt is a lightweight, technical undershirt designed for use under neoprene drysuits in warm-to-moderate conditions. Constructed from a soft, compact, quick-wicking fabric, it manages moisture during the dressing phase to prevent overheating and reduce sweating. Antimicrobial and anti-odor finishes keep the garment fresh during extended-range dives and repeated use. The undershirt maintains its thermal and moisture-control performance even if the outer suit floods, preserving comfort and function underwater. Low bulk and a close, ergonomic cut make it easy to layer under drysuits and combine with other undersuit pieces for tailored insulation and mobility.
