My favorite rain jacket is made with 3L eVent fabric, and was produced about 5 years ago by a cottage company that is no longer in business. I really liked it for its air permeability.
I try to maintain a spreadsheet of notable rain shells. While recently updating my spreadsheet, I discovered that most big names have dropped eVent from their line-up. Rab used to have several models. Now they’re almost all GoreTex. Mountain Hardwear used to have several shells using DryQ Elite, which used GE’s eVent membrane combined with MH’s own face and liner fabrics. They all seem to be gone now. REI used to have some house brand jackets with eVent. They too are gone.
Has GoreTex (in its dizzying number of variants: GoreTex, GoreTex Pro, GoreTex with C-KNIT, GoreTex Paclite, GoreTex Paclite Plus, GoreTex Active, GoreTex Active Shakedry) caught up with eVent and/or NeoShell when it comes to air permeability?
Shells with Permanent Beading Surface tech is a separate discussion. I’m aware of them and own one, the Columbia Outdry Ex Lightweight. I use it for different situations than when I want an air permeable shell.
