It was a gift for my grandson. I haven’t talked with him.

Great product, tight squeeze for 2X-3X

I'm not sure why I thought the weight rating (" capacity: 500 lbs. ") was for how big a person would fit comfortably, completely the zipped-up ThermaQuilt, but it was a tight fit for me (2x-3x), leaving little to no room to move in the torso region and no 360-degree coverage.

I left the quilt zipped over my legs and needed a second blanket to keep warm as it could not be zipped up to my shoulders, so it felt more like a ThermaQuilt 270.

My solution? I still like the product, so I bought a second ThermaQuilt on sale and will be sewing it into a wedge shape so I can enjoy my plus-size hammock camping adventures without being squeezed.

Love this item!

As a camper who lives in Texas, this is the perfect weight for most of our trips. I bought one for me earlier in the year, and love it so much, I just bought this one for my husband.

This is awesome

I had to come on and write a review. This was freaking awesome. I spend a week camping in the upper peninsula and used this all the time. Used it over my sleeping bag, used it in my hammock, in my car when I got driven in due to a bad lightning storm. Sometimes I just wrapped up in it to keep the chill out. 10/10 definitely recommend. I’m just sad I probably can’t take it to isle royale with me
