Perfect for skiing. Have used these in very cold temps as well as cooler spring temps and they regulate my body temp very well. The 3/4 length is the best for use with ski boots, as they sit perfectly above the cuff of the boot.
I love the length cause they don’t bunch up with your socks in your boots. Good waist band. Unfortunately I have a dime sized a hole about 2” below the tag in the back after about 8-10 wears. I called REI, was told I was going to need to take them there(we have a store close by) and have an employee determine if the hole warrants a return. I paid $52 for them. I’m going to save the gas and fix the hole in house. They are $85 regularly . For the price I’d just roll the dice on 2 pair of cheaper ones.
year round cyclist in the pacific northwest third pair great for mild to rainy cold weather under layer.
Fits more like a 7/8 length than a 3/4 length (5’9-1/2”)
