Not built to last.
I recently took the Squall over to Kamchatka for a ski mountaineering expedition. Was sadly disappointed in the quality of its construction. Felt happy to get a month's use out of the thing. Luckily without it being blown to smitherines in a storm.
Is it just me or has BD dropped the ball in the last few years? Seems like they are over-engineering everything, having lost sight of the more important aspects of mountain equipment..
On a more positive note, i found the size about ideal for approach/ base camps for two people and heaps of gear. With a reasonable weight.
Definitely not worth 600 dollars. IMO
