Looking at picking up a new bag this spring (or earlier if the right price pops up). I'd be using it for three season hiking, but could potentially see it used earlier spring/late fall–I'm not much of a snow hiker though.
Right now, two I'm looking at are the WM Highlite and Summerlite. From everything I've read, they're both great bags, so what I'm looking for is whether or not the summerlite is worth the ~$45 more than the highlite.
I understand the highlite is partially sewn through which could cause cold spots. Can anyone chime in on this and maybe save me some money and a few oz?
