The warmest and most breathable baselayer in the Capilene range, designed for extreme conditions and adventures.  Whether you're winter camping or walking the dog at -45, turn up the heat with a Capilene 4 baselayer.

Features a soft, stretchy feel and a smooth face that glides between layers without snagging.  The open-grid brushed fleece interior warms your core, wicks moisture and rests smoothly against the skin.  Features articulated, offset-seamed sleeves for complete shoulder mobility, hidden thumb loops to ensure wrist coverage and an elongated zipper for efficient venting.  The drop tail hem stays put under a harness.
