Helium 2 Jacket Review

Exploring the technical features of this ultralight waterproof and breathable rain jacket.

Helium 2 jacket review.

It even packs into its own pocket down to the size of a sandwich making an easy addition to your harness backpack or running vest. The helium ii is an ultralight waterproof breathable rain jacket that s lightweight enough that it can be used as a wind shirt in breezy conditions. This ultralight shell which weighs just 175g in size m is ideal for weight conscious activities such as hill running lightweight walking and backpacking or for throwing in your crag pack just in case. This isn t necessarily a bad thing since it was designed for the purpose of trapping warm air rather than providing fresh and cool air to circulate.

A technical review of the outdoor research helium ii jacket. Great for keeping the wind off without rustling or flapping about. Built for flash storm protection the 100 waterproof breathable helium ii jacket weighs an incredibly light 6 4 ounces. It manages to offer respectable stormworthiness and the extended water resistance you d expect from a rain jacket but with the weight and packability of a wind shirt.

The outdoor research helium ii rain jacket weighing in at a scant 6 2 ounces for a men s medium is fully wind and waterproof decently well featured and fits the bill for both ultralight die hards and comfort ultralighters. It has a fully adjustable hood which is an unusual bonus on such a lightweight jacket. It sets the bar as our classic pick for the ultralight backpacker. The new outdoor research helium is essentially a cross between a super light rain jacket and a wind shirt.

Since this jacket is made of nylon the helium ii doesn t offer a high level of breathability. By far the smallest and lightest ultralight jacket we tested the helium ii is our top pick for ultralight adventures. The helium ii jacket is well named.
