Smartwool 150 NTS Bottoms-
Slightly loose fit, without being baggy. Great weight to warmth ratio and nice feel against skin. I've worn them in temperatures down to zero F and been comfortable while moderately active and pushing hard while heading to the summit. The perfect amount of stretch without being overly tight. Again the best part is the moisture management and the fact you can wear them on longer trips and not STINK.
Under Armor Slider-
Smooth Heat gear fabric keeps you comfortable all climb or hike with mesh cup pocket that delivers strategic ventilation. 4-way stretch fabrication allows greater mobility in any direction. Make sure you never rub the inside of your legs again while on the trail. For any outdoor activity I suggest a pair.
A good sock is essential when you’re putting in long miles on tough terrain. Very few things put the brakes on a good hike quicker than blisters or soggy, achy feet. The deep heel pocket keeps the socks from shifting and bunching, which greatly reduces the likelihood you’ll get hot spots or blisters Fits believes in their sock so much, If for some reason you aren’t satisfied, contact FITs within 30 days and they’ll give you your money back.
