A zippered outside pocket keeps small items like your phone and sunglasses handy.

When DWR is used in conjunction with a waterproof/breathable barrier, the DWR finish keeps the outer fabric from becoming saturated so that the breathable barrier can do its job.  Recycled Polyester In 1993, Patagonia adopted fleece into their product line made from post consumer recycled (PCR) plastic soda bottles. They were the first outdoor clothing manufacturer to do so. PCR® clothing was a positive step towards a more sustainable system – one that uses fewer resources, discards less and better protects people’s health.Today, Patagonia are able to utilize more sources for recycled polyester and offer it on more garments such as Capilene® baselayers, shell jackets, board shorts, and fleece. They now recycle used soda bottles, unusable manufacturing waste, and worn out garments (including their own) into polyester fibers to produce many of our clothes.Using recycled polyester lessens our dependence on petroleum as a raw material source, curbs discards and reduces toxic emissions from incinerators.
