I am, but didn't bring it this trip. I used a lighter mid-layer- it's a Rab Alpha Flash- use Alpha Direct like the mdwi, but it's straight Alpha Direct, no outer fabric. Worked pretty well. I almost always had another layer over the top of it a windshirt or hardshell. It breathes so well that wind goes right through it (ditto on moisture), but it definitely provides insulation and move moisture outward.
