Sierra Vest
$94.99 $119.99
The Sierra Vest is designed to keep you comfortable all day, boosting core warmth and cutting out wind chill without the perpetual patch of back sweat!
- Windproof, PrimaLoft® P.U.R.E. ™ - filled panels for insulation
- Stretchy fleece side and back panels offer breathability
- Compressible insulation packs down small in rucksacks
The Sierra Vest is designed for days when you’d otherwise spend half your time de-layering and re-layering. Leaving your arms free, it targets the insulation and windproofing where you need it most, with added breathable fleece so you don’t get hot and sticky. We've used recycled fabrics throughout and reduced emissions insulation.
The insulated panels use PrimaLoft® P.U.R.E.™, a high-quality fill that’s highly compressible, warm for its weight and insulates well even when wet. Combined with a windproof fabric, this keeps your core warm on blustery mountain tops, long bike descents, or frosty trail runs in the depths of winter.
The stretch fleece panels are placed down each side and in a tapered column down the back. This allows you to dump excess moisture and heat exactly where you get hottest and sweatiest – under your arms and beneath your rucksack. It also gives you full freedom of movement when you’re shifting your balance on the bike or stretching for hand holds.
Designer's Notes
"We were very excited to be able to make one of the first garments on the market using PrimaLoft® P.U.R.E.™ technology. This technology goes beyond using recycled materials, reducing carbon emissions throughout the whole production process – and all without sacrificing any performance!"
