Sierra Designs Better Vest
Here's what other sites are saying:
The Sierra Designs Men's DriDown Better Down Vest makes an excellent ultra-warm, lightweight layering piece. The trim fit enables easy layering and reduces weight, while the 800-fill down provides excellent insulation for quick warmth. And you may be asking yourself, why sleeves' Well, they lock the heat in that you'd usually loose through the armholes of a vest, and the stretch underarm panels provide the same mobility you'd have in a vest. The single-pull drawcord hem locks in heat, and the half-zip front lets you ditch heat if you need to. Perfect for extra-cold conditions, or packed away as an emergency mid-layer.
The men's superlight Sierra Designs DriDownTM Better Down Vest has 800-fill water-repellent down, short sleeves so it's warmer than a vest and packs down small for emergency warmth.
