Just for clarification, when I wrote my comment on the jacket mentioned in this drop, the Men's Helium HD jacket, I mistakenly referred to it as the Men's Helium II jacket, both from Outdoor Research.
REI is selling the Men's Helium HD jacket for $199.00 as compared to the Men's Helium II jacket for $159.00, so this drop is well under market price.
Both jackets are made from the exact same Pertex® Shield+ 2.5L 100% nylon 30D ripstop material, but the Helium HD is three ounces heavier, has pit zips, and a hood that will fit helmets, and zip hand pockets, among the differences.
As I stated earlier, from what I have read, been told, and researched, they seem like excellent jackets, that are light, and very breathable.
Hope this clarifies my previous comment.
