Day into Night
KNOW WHAT BLOWS? Rocking a T-shirt on a sunny day, only to freeze your ass off when the temperature drops. Prevent that problem with the GoLite Ether Wind Jacket ($70, golite.com). This water-repellant, wind-resistant hooded zip-up keeps you warm, yet weighs just four ounces and folds into a Clif Bar-sized pack. Stash it in your pocket, and whether you're romping through the city or hiking a mountain, you can stay out late.
