I was a little skeptical at first because the fabric looked kind of thin and the shoulder straps looked weak. So far durability has not been an issue. Somehow everything I had to store, I found a spot for, which I wasn't sure of when I bought. A laptop pocket was a must and this one fits my 13"laptop, iPad and documents, extremely happy with that. The one time I had a lot of gear, I opened the expandable compartment and everything fit great. I have two minor complaints... I bought the Carbide one and the little zipper tabs are the same color and at times hard to find, especially in low light. I wish they had made them a different color to stand out. The shoulder straps feel flimsy. I wish they had a sturdier feel like TheNorthFace's backpacks.
I thought they wouldn't be that warm because of the LT name. But they have kept my hands warm in the teens? They feel very soft inside . When I open the hand it feels as if they are self adjusting. You know how other gloves creep off your hands, these ones feels like they are creeping on. The palm seems like it stretches a bit, like rubber gloves when you open your hand. I love that feel, because you don't have to continually pull your gloves on. The velcro doesn't snag like the traditional straps.
These are my favorite pants right now, because they stretch, so they don't have to fit baggy to allow movement. They also feel good against the skin. Build quality is there as the stitching/fabric feels tough when pushed.
