The Helium II Jacket is a super lightweight, extremely breathable and fully waterproof jacket that will keep you protected in wet and windy conditions. 

Outdoor Research says: Built for flash-storm protection, the 100% waterproof, super-breathable Helium II weighs an incredibly light 6.4 ounces. An ultra-compressible piece you'll never leave behind, it's so light and packs down so small you'll forget it's clipped to your harness until you throw it on to ward off a sudden mid-route downpour. Compressible to the size of a granola bar, the Helium II keeps you completely protected from unfriendly weather on the trail but doesn't waste space or add more than a feather's-worth of weight to your pack.

The Helium II jacket is lighter and more breathable than the original Helium jacket and can pack down really small into its inner pocket so it doesn't waste any space in your pack. The storage pocket has a small carabiner loop so you can attach it to your harness or bag for quick easy access. It's made from Pertex Shield+ fabric that is waterproof, breathable and delivers high performance at a very low weight.

The front and chest pocket zippers are all covered with YKK AquaGuard for extra protection from the elements. The jacket also features a fully adjustable hood, elasticated cuffs and a drawcord hem to help give you the best fit while keeping the cold air out. The Helium II jacket is ideal for climbing, mountain biking and hiking on wet weather days.

Very nice, not enough pockets

Nice waterproof jacket. Found myself wishing often though that it had side pockets.
