Armed with 650FP duck down, a spacious wide mummy shape, windproof Pertex® Quantum fabric, and a clever baffle construction that maximises warmth for weight, it's perfect for trekking and backpacking adventures.
Hand-filled in the UK, all our down bags benefit from never having had their down compressed before use, preserving its loft and warmth.
- L.O.F.T™ construction uses alternating wide and narrow baffles to achieve great warmth for weight.
- Sleep comfortably on your side thanks to the sidewall baffles, which reduce cold spots and ensure you’re not lying on a seam.
- A second shorter zip with integrated snap closure allows you to use your arms while retaining heat in your sleeping bag, ideal for cooking in the cold.
- Cinch in the hood to seal in the heat, while the synthetic insulated collar sits snugly around your neck.
- Sleep in a relaxed, comfortable position thanks to the roomy, anatomically shaped foot box.
- Keep valuables and essentials close at hand with a zipped internal stash pocket.
- Wide mummy fit gives space for extra layers when night temperatures plummet.

Perfect!
Size: 3 Pairs - Gray, Green, Pink
When my heel skin started cracking, I of course found the internet hacks that went along the lines of put some moisturizing something (cream, Vaseline) on your feet and put socks on and go to sleep. Somehow many issues. While putting on the socks, I already wiped off the moisturizer. It feels terrible. My sleeping self hates socks apparently! I always kick them off, the socks are covered in moisturizer, and it’s all over my blanket. Yuck!
So when I found these socks I was unsure but willing to try. These are exactly what I needed! They have this gel-y coating inside that does not absorb the moisturizer, so it actually gets absorbed into your skin. They are snug without cutting off circulation, and along with kerasal, my heels are being healed! Could not recommend enough.

They keep sheets from getting greasy.
Size: 3 Pairs - Gray
These are good. I like that I can put lotion on my heels when I go to bed and not get my sheets greasy. They do a good job on that and a pretty good job keeping the moisturizer on. Since the toes are open, they aren’t hot.
The gel doesn’t seem to do anything, though.

Impressive
Size: 3 Pairs - Gray, Green, Pink
These socks are so cool and I have used them every night for a week and can see a difference. I am using them with the gold bond heel lotion.

Seem to help heal, but doesn't reach the balls of my feet
Size: 3 Pairs - Gray, Green, Pink
Only can wear when I am sitting down because they're to slippery to walk in
