The wind gusted into the 30s near the top of Swifty. That morning I considered adding a lighter capilene base layer but opted instead for the Cap 4 and a mid-weight under my shell.

No problem. The Cap 4’ s brushed fleece lining and snug fit kept my core warm, while its breathability staved off that uncomfortable clammy feeling some capilene can give you. When the wind picked up, I zipped up the tall collar and donned the anatomical hood beneath my helmet to block out the breeze.

It worked, plus it made me look like a ninja. Patagonia’s Cap 4 hoody just earned its place in my base layer rotation.
