The Flash Anorak is a shell unlikely any other. This innovative jacket boasts one feature that sets it apart from all the rest - it has no back! This ultralight windshell can be carried in a pocket that attaches to the waist belt of any day pack. When temps cool down, unfurl the anorak and put it on without removing the pack, and when the sun comes back out, take it off again without even breaking stride! The shell is attached at the waist to prevent flapping and provides excellent protection from wind and even light showers. Made from innovative Araneum fabric, a 20 denier nylon ripstop fabric that is 33% stronger and only 10% heavier than 15 denier fabric, the Flash is both incredibly lightweight and surprisingly durable.
