I haven't worn this jacket yet. It's still NWT. BUT, I do have the Alpha FL and the active shell is amazing, wore it in tropical thunderstorms in a rainforest, was dry, not clammy feeling (even in 26c weather) and wore it skiing in -20c (shell layer).The difference between the Alpha FL and this Tecto is the pocket placement, everything else, the same. Reason I didn’t wear the Tecto. 1) I'm thinking of sending it back, platinum color wasn't the color I was expecting (darker then photos). 2) The weather's 32c where I am now, sooo..Great jacket, great material. Stuffs into it's own included sac, which BTW is the circumference of a 1.5L Evian bottle, but half the height.
