Outdoor VitalsLoftTek Hybrid Booties

These are well made and keep your feet warm at night in the sleeping bag @ 6 degrees.

These work as advertised. They kept my feet warm all night long during cold weather.

I do quite a bit of winter camping.I have a very warm quilt and sleep system, but sometimes after a long day of cold toes, it's nice to have a little bit of extra insulation on your feet.These booties are so warm!Slip them on before you snuggle into your sleeping bag and your feet will never be cold.The loftek insulation is a mix of down and synthetic insulation that keep its warmth even if it gets a little damp. Unlike pure down that highly susceptible to moisture.I do wish they had a rubberized bottom so you could wear them like slippers, but that's not a huge deal as they compress enough to slide into camp shoes for those late night calls of nature.If you suffer from "popsicle toes" like I do, these will serve you well.Very highly recommended.

The pair I was sold is thin and has very little filling. They don't provide meaningful insulation even in cool (~40f) temperature. Very disappointed, especially for the cost.

To be clear, these booties are not for relaxing around the campfire after a day on the trail, or for giving your feet a rest while walking around camp at the end of the day. That's a good way to ruin them. These are simply for cold weather camping and used in your sleeping bag or top quilt to provide an additional, lightweight layer of protection from the cold. And they do that well.They're made of a very lightweight material that will hold up if you're cautious. I believe the fill is likely that new "fabric" made of down fibers, but could be wrong on that. The boots are warm, but somewhat delicate, so just be careful with them. There's no cord-and-spring-button closure at the ankle. Instead, the ankle has an elastic edge, which I would expect to break down over a couple of years or so. Time will tell on that one.I'll be using these when I'm cold-weather hammock camping. Recommended.
