This Acronym lightshell jacket is killer. For those non-techwear nerds not already aware, Acronym makes clothing for ninjas of the future. Made from a softshell Schoeller fabric, this particular offering is water resistant, has a cotton outer face and has a jacket sling. What’s a jacket sling? Oh, you know, just a sling for your jacket—that way you don’t have to drape your jacket around your shoulders or tie it around your waist like the ill douche in an '80s rom com. This jacket weighs only 594 grams, which, at $1000, means it’s less than $2 per gram.
