Really like these
So, I had my eye on these for a while and decided to pull the trigger on them. I’m not disappointed. I haven’t used them for touring yet and I’m concerned that they won’t breathe but I’ll update my review later. For downhill, awesome. I’m not sure why people suggested that these are inflexible or undersized. After trying on a few pairs, I went with a small as I wanted to limit profile - as a 195 lb 6 foot man, they fix perfect. I have a thin waist and a very athletic build. If you’re running downhill on cold days, pull the trigger and size down.
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.
Great…. but could be improved
Comfortable and warm. I would suggest sizing down. And for men, a zip fly is a must when used for skiing. If Stio ski pants can have a zip fly, this undergarment needs one too as it’s a real challenge at the urinal. The drawstring could also be thicker too. Had to double knot these to keep them tied under the ski pants. Great product and avoids the need for long underwear but it could be improved.
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.
No Front Fly, No Buy
No fly, for a man?? Would buy these instantly if they had a fly, but without one, completely useless. So surprising for a company that makes all their products stand out above the rest.
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!
