> PodSacs Black Ice vs PodSacs Alpine 50 - which is better for Scottish Winter Mountaineering & Climbing?
Speaking as someone who has just replaced a well-use Black Ice with an Alpine 50, I would say neither is ideal for single-day Scottish Winter use.
Both are at the size where the one sack will just about do everything and I think the Alpine 50 is totally superb in that regard, although very pricey. However IMO both are too large to be ideal for the majority of use I would put them to in Scotland. Unless you need the capacity for multi-day Winter expeditions there are better alternatives.
I would suggest having a much closer look at the Alpine 40 and look at saving yourself come money in the process.
