The helium ii jacket is well named.
Helium 2 jacket review.
By far the smallest and lightest ultralight jacket we tested the helium ii is our top pick for ultralight adventures.
It sacrifices some protection and features to keep things minimal but is still a great option for an emergency layer or anyone wanting to shed ounces.
The new outdoor research helium is essentially a cross between a super light rain jacket and a wind shirt.
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.
It has a fully adjustable hood which is an unusual bonus on such a lightweight jacket.
A technical review of the outdoor research helium ii jacket.
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.
Built for flash storm protection the 100 waterproof breathable helium ii jacket weighs an incredibly light 6 4 ounces.
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.
Minimalists this is your solution for maximum storm protection.
Exploring the technical features of this ultralight waterproof and breathable rain jacket.
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.
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.
Great for keeping the wind off without rustling or flapping about.
Since this jacket is made of nylon the helium ii doesn t offer a high level of breathability.
