Quick dry warmth featuring micro fleece waffle-lining.
But Simms takes this hardworking mainstay into the 21st, with the boosted warmth of waffle-lined micro-fleece internals. ColdWeather LS features include quick-dry performance, potent UPF 50 sun protection, and chafe-free, off-shoulder seaming for added comfort. Stash gear in two super-sized, top-close chest pockets. And stay effortlessly stylish in these ultrawarm, brushed-flannel performance plaids.
UPF stands for Ultraviolet Protection Factor and indicates how much of the sun's UV radiation is absorbed. A fabric with a rating of 50 will allow only 1/50th of the sun's UV rays to pass through. This means the fabric will reduce your skin's UV radiation exposure significantly. All of our UPF finishes last the life of the garment, an industry standard of 30 washings.
