Rab Bergen Event waterproof 3 layer pants with 3/4 length zippers and shock cord ankle closures.  Amazing winter pants for deep snow expeditions.  Wore on one trip in the Sierras snowshoing, no rips or holes.  Work very well in high exertion/cold temperature situations.  Wore them with capilene tights and was perfect combo for all day.  Happy to share any up close pics, look brand new getting rid of them since I won’t be doing any deep snow trips this year.
