The Bare Ultrawarmth Mens Base Top Layer Drysuit Undergarment uses 230-gram Omnired™ Infrared stretch fleece to deliver warmth and moisture management for scuba and diving under a drysuit. The smooth-face fabric layers easily against other garments, while the fleece-brushed back provides warmth and moisture-wicking performance with Microban odor control for extended underwater use.

Quick-drying characteristics keep the surface dry and comfortable when the suit is vented or removed, while flatlock seams minimize chafing. The pullover design with a low crew neck and low-profile retractable thumb loops aids donning. The high warmth-to-weight ratio offers the right balance of warmth and breathability for dive applications, making it suitable for scuba setups. Available in men’s and women’s top and pant in various sizes.
