These are great. You won't notice you're wearing them but you WILL feel warmer. 2 layers from jeans and then these thermals is just enough to get you through any climate. Just know if you buy them for a winter in London and Paris like I did, you might end up sweating. The weather can warm up on short notice and buildings always have their heat on full blast.

Nevertheless these are great thermals that will save your lower half. Everyone says they're too short, but if you're wearing them I'm assuming you've got boots or something on so your ankles shouldn't be a concern.
