After over 2 years of use, the jacket still looks new. I do wash it and care for it appropriately but it has also endured some hardships and has been used countless times. The medium fit for me is perfect: room to put layers underneath but not bulky and unshapely in anyway. The arms are more of a slimfit but I enjoy that design personally. My rubbber and cord accessory zipper pull tab broke about a year ago but I just tied in a piece of cord into the metal zipper to replace it.
My only con with this jacket is that the zipper can sometimes stick and be difficult to pull up or down. Tensioning the fabric helps but I'm not sure what I can do about the stickiness. The zipper creates a waterproof seal for the jacket which is important but it could be much easier to pull.
I would buy another one of these jackets in a heartbeat. In fact, I would buy one today but they don't seem to be making them anymore nor can you find them on the internet. Mountain Hardwear: Bring back the Drystein!!
Cons: Zipper pull tab, zipper stickiness
