Living in your yoga gear, climbing shorts, and flip flops year round would be pretty nice, but most of use aren't lucky enough to live on a Thai beach. For those of us in chillier climes, Prana's Merced Men's Jacket is a weatherproof godsend, with a 10K waterproof and breathable membrane, 650 fill down insulation, and cozy fleece lined adjustable hood that'll save your bacon when temperatures are in the sub sending zone. In case the 10K membrane isn't enough for you, Prana finished the nylon blend face fabric with a DWR treatment, which encourages water to bead up and run off rather than soaking into the fabric. Together, these water besting technologies keep the down warm, lofty, and light, so the chill won't seep into your bones. Prana designed the hood and hem with drawcords for easy adjustment, and lined the hood with super soft sherpa fleece to keep all your important brain heat from escaping. The polyester lining slides smoothly over layers so you can fine tune your insulation when the weather's changing, and the internal cuffs hug your wrists for a snug, comfy feel that's key when you're trying to work up the courage to venture out into the cold.
