Too heavy for backpacking and the fabric is very fragile. The velcro tab snags every time its opened and leaves either a run or a hole which spreads. Velco on this was a very bad idea. Use small snaps like the ones used to attach it to the bags inner loops.
Light, breathable, with great attention to detail. My go to jacket for most of the year.
As others have said, comfortable right out of the box. Prefer the feel of my Lowas but that is going to be a personal fit/feel type thing. Construction appears good with the exception of the gimmicky heel lock strap. A relatively flimsy feeling nylon strap runs from the heel to the eyelet on the outsides of the boot. The boot is stiff enough that tightening this up doesn't appreciably affect the feel but after only 2 outings, the straps vulnerability was demonstrated. Easily cut by rocks, etc. Reinforced mine with shoe goo and am hoping that it will hold up.
Addendum: after several snowshoe outings, have to agree with others that this is definitely NOT waterproof.
Have owned Patagonia's Half Mass, various Timbuk2 bags, as well as a couple Crumplers. TNF has outlasted them all. Great in wet commutes, and big enough for a padded laptop case as well as office clothes and lunch. Quality is good and the warranty is unbeatable.
