A bit of new gear I have my eye on is a replacement for my fleece pullover, which at 7oz is somewhat on the heavy side.
- I have been really impressed so far with Theresas western mountaineering vest – it's a miracle at 3oz. However, it's down and useless when wet. Theresa carries it for extra warmth at camp and has a fleece as her primary warm layer.
The Bozeman Moutainworks cocoon vest is an interesting candidate. It's synthetic, and so retains it's warmth when wet. At 5.3oz it would save me a precious 2oz and probably be a much warmer layer.
The added bonus, is that it would give me an excellent boost to my sleeping bag, when the temps really dip down.
