A shell jacket keeps you safe from rain and wind. Breathable membrane materials make shell jackets more comfortable than the raincoats of yesteryear. The lightest of shells are made for sports use - they pack down very small and are very light to wear. Middle-of-the-line shells are multifunctional and they can be worn pretty much year round. Our sturdiest shell jackets will serve you even in extreme conditions, whether you’re out ice climbing or hauling a sled in a snow storm.
