Versatile, warm camping blanket

I was looking for an adventure blanket with a little added warmth that I could use for sleeping late spring to early fall that would also work as a ground cover to sit on or let me dog use. My parameters were weight (under two pounds), size (at least 4.5’ by 6’), and material (at least 30D). This mostly hit my requirements, and what set it over the top is the added dimension of working as an hammock under quilt that also can zip over top as a cocoon. I have used this on a couple of camping trips. This will also work for canoe camping and bike packing if it can get it to compress down enough to make it packable. A friend used it on an overnight backpacking trip but it is too bulky if space is a factor.

Pros: Versatility and varied uses, warmth, comfort, feel against the skin, and footprint.
Cons: At 2 pounds the weight is adequate for my needs but it is a little bulky for minimalist adventures
TBD: I was hoping this would be rugged enough to withstand ground use. The material at 20D feels a little thin, so I question how well it will hold up to this use.

Overall happy with this and would recommend.

Bought this for my sister, she loves it!

My sister needed something like this for hammock camping, so I bought it for her. I guess it should have been obvious by the fact that there are drawstrings at each end, but she was super excited that because of the drawstring openings, she could walk around in it!!
There’s really nothing that mentions that, and just today (after reading and studying on this purchase for months) I just saw a picture of a girl that looks like she’s jumping in it and I see her feet, but other than that, there’s no mention that you can walk around in it. ( I attached a pick from grand trunk.) That would have been nice to know. I with they had listed it among the other benefits of owning one. But all on all it is a pretty nice and versatile piece of gear. I agree with another person who said it just needs zippers on the side for armholes! I think I will add them to make it the perfect piece of gear!
I also recommend the grand trunk mozzy 360 big net, it’s great because it has a “floor” so you can store stuff inside to keep bugs and critters out of it. I love grand trunk. They offer great, well made products with multi uses.

Insulation of a napkin

I found this annoying to put on in that you have to unzip the whole thing and then balance it on your ridgeline while you attempt to zip it, and it seems like they engineered a zipper to snag the fabric. I much prefer an under quilt that attaches by simply looping an elastic band over the end of the hammock.

Now, if this was actually warm I could see why the extra set-up fuss would be worth it, but it has the insulation of a napkin. It is rated to 50 degrees which means it is probably practical to about 60, but even at 60 I was freezing. Luckily I had a survival blanket.

The appeal I guess, is that it is inexpensive. That said, it is money in the garbage as far as I am concerned. I used it once, understood it is nothing more than a summer blanket and requested to return it. Denied because it was used once. If you are planning to camp in anything resembling a cool late summer or early fall temp .... Save your money and don't buy this.

Excellent Lightweight Blanket/Under-Blanket!

This is a very nice lightweight blanket for relaxing in the hammock on cool Southern nights. I use it like a sleeping bag, putting it under me then wrapping it over me. Living in the South we have cool nights and this weight of blanket is perfect. I enjoy evenings laying in my Grand Trunk Deluxe Hammock and sometimes falling asleep and waking up in the morning!. I'll try this blanket as the season changes to spring as a layer under-blanket. I've always had excellent customer service at Grand Trunk, usually with simple beginner Hammock user questions. Shipping is very fast and the quality of all of my hammocks, stand, straps, etc have been perfect!

Convenient, comfy, and warm

The ThermaQuilt is great and versatile. It kept me warm on the lake in October. For longer backpacking trips, I’ll upgrade to the down hammock. For quick fun trips, this is perfect.

Works pretty good. Wish the ends closed a little more securely.

Quality control keeps it from being great.

Overall the product is good. It is easy to use, warm, and comfortable on cool Wisconsin days. Unfortunately mine has 1 o 2 loose seams. It doesn't seem (no pun) to impact function so I'm still debating the hassle of returning.

Nice blanket. Poor customer service

The blanket I ordered arrived defective with a detached pullstring in the hood. I’ve emailed customer service twice for help in the last month and have received no reply. Be mindful of this when you buy from Grand Trunk.

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

Cover up

I got the hammock quilt quickly and had a chance to use it this weekend. I didn't use my hammock for this trip, instead used a cot in a tarp tipi. With the weather a bit cool, the hammock quilt converted quickly and easily to a soft lightweight cover over my sleeping system. Just the right amount of added layer for a very comfortable night. And, when I was packing up, it went back easily into the stuff sack. It will be a great addition for cool fall evenings at the beach house too! Versatile and much less expensive than other products.

Innovative Hammock Quilt

I really like this 3-in-1hammock quilt! What a great way to have 3 nice products to use with a hammock or as a sleeping bag/quilt. When I got mine, I was disappointed to see one of the tie attachments in the inner pocket of the quilt was missing, but I'm hopeful that the good customer service at GrandTrunk will send a replacement. In the meantime, it's easy to rig up a rope that will serve the same purpose. I tested out the quilt one night in the hammock, and it kept me very warm and cozy. I'm also pleased that it packs down to a very small size, so I can fit it in my hiking backpack or use it when I kayak camp. Thanks, GrandTrunk!

solid mid-low temperature option

I haven’t been able to take this on an overnight trip yet, but as the temperatures start to drop and become more fall-like in my area, this has been an easy to carry lightweight addition to stave off some of the windchill while reading in my hammock. I’ve never stepped up to extreme light weight backpacking, but it blows my mind that something this light can be this warm.

Love it

I have Used this under-quilt for that last three years, sleep at least 25 night in north central Arkansas from march though late October. Back packed and car camped both. Last march went backpacking in the Ozark mountains, Indian creek trail of the Ozark highlands trail, great trail by the way. It was cold down to the lower 30, took a ENO’s inferno under quilt just in case. I slept in ice breaker Marino wool top and bottom, wool sock and my Marino wool cap my wife made and I stayed warm. Did not use the ENO’s, used it to cover my dog, who sleep in her own hammock. I Would not want to get much cooler than the rated 40 degrees. I am 6’ and weight 238, I’ve got a little extra meat on me and can tolerate a fair bit of cold but I slept well. The bag is snug, but I can get is zipped over my head which helps. I wrote the review today as I just bought one for my daughter, our annual spring break backpacking trip. Gonna finish off the Ozark highlands trail. June of 21 used on a 8 day paddle trip to the boundary waters, it was just the right weight and comfort level.

Comfy and cozy
