Hello Guys/and gals, When planning what clothing to take with you, when space is limited. I found an item called Sealskinz, they are basically waterproof socks, the manufacturer also makes other items, but I have not tried them and in all honesty, am not going to order them, so if anybody has something other than the socks, feel free to chime in here. I live in AZ, not the best place to try out cold or wet weather gear, but I did live in Maine for a few years and remember the conditions there, that is what prompted me to buy a pair. You never know where you will end up in your travels. These socks have a strange feel to them and seem to be multi layered in different fabrics sewn together………I’m not a scuba diver, but that is what it reminds me of. They are thick and not at all like regular fabric socks we are used to. The only ” field test ” I have done is to fill the bathtub up part way and get in with the socks. I walked around in the tub for good amount of time, and my feet were dry as a bone. The manufacturer claimed that your feet will be able to breath wearing them, so I kept them on all day…….they do indeed wick moisture. they do stretch to a limited degree, but not a whole lot, so its important to order the right size. The only thing that is a downer is that these are on the pricey side. That’s why I only own one pair………………why only one ? because I’m cheap! that and I intended them to be packed in my BOB, along with 1 pair of winter socks and two pairs of regular socks.
