So it looks good for the snow... how about the summer when the snow melts? I'm worried about the back panel really heating up in the summer...
That is the compromise when using a winter pack for warmer weather pursuits.
Because you don't want a ventilated pack in snow because snow will build up in the mesh backing, the backpanel in a winter pack tend to be hot for summer use. However, if you use a summer pack in snow, you lose backpanel entry, closed backpanel to resist snow build up, and an exposed hydration hose that is more prone to freezing.
So it depends on what you want the pack to function better for--summer use or winter use.
