Best bib I have used

Rating:*****

I have been a softshell pant guy for the last few years, but I have to say I am very happy to be back in a Gore pant. The ventilation is excellent, and the breathability of the fabric itself is excellent. The softshell upper on the pant is the clincher - you get the added snow protection without overheating. One of the few pieces that I have ever owned that I would not change a thing on.

I like!

Rating:*****

I have been using these pants for ski touring,and ski mountaineering!
They are light so they pack well in your pack.
They work well for inbounds skiing to,but a little thin when you are riding the chairlift!

You would be better off with the free thinker pant for really cold inbound skiing days!

SWEET BIB

Rating:*****

After shopping around for a backcountry bib I bought these. What sold me was how soft the material is for a gore tex pro shell. I have done some hiking and ski touring in these and they have been perfect. Anything in the north face summit series to me is still top notch.

Great product

Rating:****
Used mine for a camping trip in Baxetr State Park in Maine in winter. Great fit, maybe a little loose, but great breathability and water repellency with plenty of venting options. Lightweight as well.

great shell

Rating:*****

i have done everything from skiing to ice climbing in these and i love them. they're comfy, just roomy enough and aren't too warm for a bib.
