I know this isn't art, but I had to put it out there someplace! I love my Schnees pac boots, but when it gets really cold out here in Montana, the liners that come with pac boots, a 3mm wool blend, still aren't quite enough for me. I tend to wear a medium weight merino sock and dislike very heavy wool socks. I have found potentially the best thing ever....a shearling liner!
These are custom made to your size out in Oregon. You send them your street size, plus a few measurements. Shipping was insanely fast and all communication with them has been fantastic. My feet literally feel like they're just being hugged by fuzzy fleecy goodness....I have only worn these down to 12*, we haven't gotten below zero again, but I'm definitely going to be updating my review of them long term. If you have Schnees boots too, I would recommend sending them a tracing of your current liner. Mine arrived a little too wide in the heel and I had to modify them with my sewing machine. So to prevent that, just trace your liner to be on the safe side!
So far I have had zero issues getting these to fit under my riding suit and my overpants that I wear when it's really cold. Get yours here!
Surprisingly, I have not gotten tons of hay stuck in them. It's been easy to brush out, but it does give me incentive to wear a gaiter or my riding suit over them.
