Light, breathable, and waterproof, the Immersion Research Men's Zephyr Long-Sleeve Paddling Jacket provides plenty of versatile protection without the sticker shock. It's made with a paddle-tested WhiteOut waterproof and breathable membrane and has a neoprene closure at the neck, hook-and-loop cuffs, and a drawcord hem to keep you dry when you're fishing, SUPing, or shooting moderate whitewater. A mesh inner layer prevents things from getting clammy, and fully taped seams make sure moisture doesn't creep in where it's not wanted.
A basic jacket meant for all around paddling features ergonomic seaming for greater mobility and comfort. Made with waterproof, breathable 2-layer fabric and an antimicrobial mesh liner, hook and loop neck closure, hook and loop wrist closures, front chest pocket, and drawstring waistband. Seam taped throughout.
