North Face Nuptse 2 Vest

If you're headed to an area where it might be cool but never below freezing, favor a vest over a coat. A good vest keeps heat around your core – the key to staying warm – yet saves you space. Our pick: North Face's tried-and-true Nuptse 2 Vest. Packed with 700-fill down yet not bulky, it packs down to the size of a large Tic Tac. What's more, it can take a beating; we snagged it on a branch and came away unscathed. [$149;]
