Is there any drawback to wearing full-length compression tights as a base layer under a wind/water proof shell?
I've worn them for mountain running but never above 10,000 feet, and it's usually been for less than 5 hours. Like them a lot.
Now I'm wondering if it would be good to wear them on a 2-day end-of-winter 14er climb in lieu of longjohns. My concern is that they might adversely affect circulation in the feet while at altitude.
Thanks.
