What Our Gearhead(R) Experts Are Saying:"Perfect for warm-weather paddling when you need spray protection but not full coverage. The hydrophobic fabric really does dry faster, and the neoprene bands seal perfectly without feeling restrictive."Warm-weather paddling requires protection that doesn't create overheating, so we developed the Immersion Research Nano Short-Sleeve Paddle Jacket for conditions where spray deflection matters more than thermal retention. Lightweight hydrophobic 2. 5-layer polyester construction breathes efficiently while neoprene neck and bicep bands seal out spray, creating targeted protection that adapts to temperature and conditions.
