Scubapro K2 Extreme One-Piece Undersuit (Size Large)
By Scubapro | Part #: 78.171.400 | Premium Dual-Fleece Thermal Barrier | Size: Large
Stay warm on extreme cold-water dives with the Scubapro K2 Extreme One-Piece Undersuit. Specially engineered for trilaminate, fabric, and neoprene drysuit diving in freezing conditions, the K2 Extreme features an advanced dual-fleece material blend (629g/m²) that traps insulating air against your skin while managing moisture evaporation.
Designed for maximum agility under heavy drysuits, this plush undergarment includes elastic thumb loops and ankle stirrups to prevent annoying sleeve and leg ride-up during donning. A convenient 2-way front zipper allows easy relief access, while side compression panels ensure a streamlined, bulk-free fit underwater.
Maximum Cold-Water Protection & Comfort Features
Tested in extreme Pacific Northwest and polar waters, the K2 Extreme delivers high thermal protection without restricting range of motion. Includes zippered chest pockets for storing car keys or accessories topside, plus crush-resistant elbow and knee padding for extra durability.
