The helium ii jacket is well named.
Helium 2 jacket review.
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.
Minimalists this is your solution for maximum storm protection.
The new outdoor research helium is essentially a cross between a super light rain jacket and a wind shirt.
By far the smallest and lightest ultralight jacket we tested the helium ii is our top pick for ultralight adventures.
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.
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.
Finally the jacket is an impressive wind blocker i ve used it and the prior generation helium ii on cold days while mountain biking to take the sting out on a frigid descent and provide some heat trapping warmth.
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.
Exploring the technical features of this ultralight waterproof and breathable rain jacket.
Built for flash storm protection the 100 waterproof breathable helium ii jacket weighs an incredibly light 6 4 ounces.
Great for keeping the wind off without rustling or flapping about.
A technical review of the outdoor research helium ii jacket.
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 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.
Since this jacket is made of nylon the helium ii doesn t offer a high level of breathability.
