Absolutely AMAZING
I purchased a couple pairs of these to go skiing and they rock! Beats out long johns and other warm compression wear. They are so comfortable and move so much better while skiing. The only downside is if I wanted to wear them to do other things is there is only 1 zipper pocket available but that's minor as they are primarily worn as a base layer. I did see some reviews saying they run a bit larger which is true but I think they're very comfortable for their fit.
Good so far!
I bought then as a mid layer for my ski pants. I am very happy with the fit. I am impressed with the quality. I have not yet had a chance to put them to work. My friends who own a pair swear by them so I am sure they will be great. I wish they had side pockets. That is my only constructive comment.
Great product but needs 1 change
These knickers are great! They saved a very cold weekend of skiing for me at Targhee! However, from a male point of view. . . . . . I'd highly suggest taking the zipper from the pocket. . . . . that I will never use and adding that as a zipper for #1 access. . . . if you know what I mean.
Great product
It’s true to size. Not too bulky that provides enough insulation, that fits well with my Stio non insulated bibs. Plan on using these for cold days. Very nice that they don’t interfere with socks or boot tops.
Best base layer ever
Completely forget I have them on. Fit perfectly, keep me warm, above the boot so no bunching in the boot, don’t overheat and always warm enough so I can focus on what I’m doing. Outstanding base layer.
Nicely designed/ good materials
This is my second pair recommend them for skiing on or off slope or just ice fishing or general outdoor winter use nice level of insulation really have helped in windy/ damp chairlift ride
Best Insulation!
Bought these for my son after he tried his brother's Fernos and loved them. Now everyone in my family has them for skiing. I recommend them to everyone!
Perfect Mid Layer
Great mid layer on chilly days. Paired with long underwear, this knicker and my environ pants, I was very comfortable all day with temps as low as -15.
Terrific pair of pants
these have made a huge difference on cold, Northeast days. I used to layer with a mediocre effect but these have made the process easy and warm.
Great insulation
I only wear shell ski pants. I bought these for super cold temps and they essentially turn my shells into insulated pants! Great piece of gear!
