  • Arch support stretch band to help keep sock in position, no slipping or bunching
  • Patterned bend and regular knit at front mid ankle to help prevent bunching
  • Above calf height for warmth and comfort
  • Nylon reinforced toe, heel and sole for ultimate durability
  • 43% merino wool, 40% acrylic, 13% lycra, 4% polyamide

Note: Use of a technical sock is required to obtain the full functionality of Gore-Tex boots

Great Thick Socks
These socks are very thick and warm. Riding in 70 degree weather was not too warm. Riding in 40 degree was not too cold.

STAY COSY THIS WINTER IN THESE INCREDIBLY WARM FEATS OF FABRIC ENGINEERING
Thanks to the Terry construction, the Klim Mammoth socks are likely the warmest socks available on the market. Luxuriously thick, they are great when worn with Gore-Tex boots (or without for that matter) to wick away the moisture, however, are just as much a godsend when your feet are particularly nesh like mine, suffering from the cold when temperatures drop. I don’t care where I am, how stunning the scenery is—if the cold starts to burrow through my feet like a worm, then I can’t concentrate on much else. Blocks of ice for feet are about as much fun as a funeral. Stay cosy this winter in these incredibly warm feats of fabric engineering.

Can't wait for the cold weather!
Living in Minneapolis means riding in cold temps. 25 degrees is the lowest I'll ride in, and it looks like these socks will be the best ever. Thick, soft, and they'll stay up on my legs (hate it when knee high socks fall down). Looking forward to the first below freezing ride!

Excellent warm sock, runs large
These are nice, thick, comfortable, WARM socks. If you're riding in cold weather and have a little room to spare inside your boots, you won't regret getting these.

For sizing, guidance shown on other web sites is SM = 4-6, MD = 7-10, LG = 11-14. However, I'm a 6-ft 240-lb gentleman with shoe size 11, and I found the Medium fits me with room to spare. They pull up to just below the knee, and would probably fit a size 12 foot just fine.

I wear a size 9 shoe and these socks are a little long from toe to heel for my liking, but I kept them.

I need really warm socks to ride to work in Minneapolis (5:45 AM, highway speeds) when the temp is as low as 25 degrees. These socks are thick, soft, look and feel like they are up to the task. The upcoming change of season will tell the tale... I can't wait!

I just got to see what a $33 pair of socks will wear like. Honestly, I want more than just a cotton wad of a sock flopping around in my boots.

Previous experience with Klim Mammoth socks. These newly designed socks are even better than my old ones, these are GREAT!
