Regulator cubed: our warmest weight in a versatile full-zip style. The fabric is densely woven so it provides some wind resistance without a shell. Wear the jacket as outerwear in mild conditions or as a mid layer when the weather threatens to plaster you to a wall. Details: stretch panels in critical flex areas (sides, inside elbows and wrists), adjustable drawcorded waist to seal out snow, zippered pockets to shelter cold hands, clean-finished seams for comfort. Cut trim for layering; buy a size up if you want a looser fit. Made in USA.
