In reply to speedysi: i have both a DAS and micro puff (neither bought at anywhere near retail btw). The DAs is great in winter and for skiing at -40! it is a really warm solid bit of kit. that will get carried most days in scottlant this winter. it only down side is it bulky. it does stuff quite small, but i carry mine at the very top of my pack and put it on whenever i stop. i tend to dress lightly. my micro puff get used spring and autumn and for summer alpine. it is much thinner than the DAS, but still has the same excellent hood. it would be a great belay jacket for scottland, but i have a DAS so i use that. The DAS is only avalible in the states for some bizare reason, you should be able to order one for arond £150 (uk retail was around £200). you could alwaysa get a micro puff vest as well and compine the two jackets. so still dress lightly, layering the the vest over the top of your climbing where when your seconding and adding the micro puff on belays.
