The Outdoor Research Women's Helium UL Pant is a 164g waterproof overtrouser for people who would rather not carry one. Built for minimalist hikers and trail runners, it uses Toray Dermizax™ 2.75-layer fabric to keep the rain out while letting heat escape.

These live in your pack until the weather turns. The back pocket doubles as a stuff sack, so they pack down to almost nothing, and ankle zips mean you can pull them on over boots without taking anything off. Fully seam-taped, windproof and breathable, so they are a proper waterproof rather than a token gesture.
