The Broad Peak Vest is a stupidly versatile piece. Throw it on over a top or use it as an insulating midlayer. The sleeveless option gives you less bulk & a greater range of movement. The 750 fill power micro baffle, goose down filled vest is warm & super lightweight. Down has the best warmth to weight ratio properties of any insulating products. There are two large hand warming pockets that are big enough to stow a decent sized pair of gloves & when not in use the vest packs down super small. The two way front zip mean you can get at your belay plate without having to hitch up or remove your jacket & the tough wind resistant Pertex outer help the down to retain essential body heat.
