UV1 CX360 Undervest Long Sleeve

The Elbeco UV1 CX360 Undervest Long Sleeve is engineered for serious water professionals who demand lightweight thermal protection without bulk. Built for anglers, boaters, and marine law enforcement, this underlayer addresses the real challenge of staying warm during extended time on the water while maintaining full mobility and freedom of movement. Whether you're running a patrol boat in early morning conditions or spending all day on the deck, the undervest eliminates the guesswork of layering by delivering consistent insulation when worn under your primary gear.

The long-sleeve design works with the UV1 CX360 system technology to manage moisture and regulate body temperature across changing conditions—critical when you transition between active work and idle periods where sweat chill becomes a genuine hazard. At 0.69 lbs, the undervest adds negligible weight while the fitted proportions (sized at 16.5 inches across key measurements) ensure it layers cleanly under tactical vests, life jackets, or standard boating apparel without creating drag points or binding during reaching or steering movements. The construction prioritizes durability against saltwater exposure and the constant friction of marine gear, extending the working lifespan of your thermal layers in demanding saltwater and freshwater environments.

Professional operators—coast guard personnel, fishing guides, charter captains, and marine security teams—benefit most from this purpose-built underlayer because it eliminates the bulk and slippage of standard thermal wear that compromises gear integrity and comfort in tactical settings. The compact packed dimensions (8.5 x 2.3 x 13.9 inches) make it ideal for vessel storage or emergency kits, and the long-sleeve configuration provides consistent coverage that stays in place during high-activity scenarios or prolonged seated operations. Pair the Elbeco UV1 CX360 Undervest with your existing protective systems for reliable cold-weather performance that won't interfere with belt-mounted equipment, communication gear, or primary body armor.
