For unrivaled performance, Patagonia's most versatile fleece offers you stretch and warmth while bouldering or heading straight to the bar for morning coffee. The Crosstrek 1/4-Zip offers next-to-skin comfort when engaging in intense activity, durability for use that extends season after season and elasticity for maximum freedom of movement. Thanks to the Polartec® Power Stretch ™ fleece it is made of, it has a soft exterior that stays flat and glides easily under other layers. The soft brushed inner surface traps heat and is breathable to keep you dry. The flat-seam construction reduces the volume of the garment and minimizes chafing under the shoulder straps and harness of the backpack. The design of the cuffs allows you to roll up the sleeves at forearm height, simplifying the movements in climbing; thumbholes hold sleeves in place when extra protection is needed or extra warmth is needed. A zip pocket placed on the back above the right side holds small essential items.
