Grand Trunk 360 ThermaQuilt 3-in-1 Hammock Underquilt Converts to Sleeping Bag or Blanket 40 F Rated Lightweight Insulated

Perfect. Light, portable and oh so warm. Hammock into the winter months without fear of losing your fingers and toes Read more

Would you rather sleep in a taco or a burrito? Underquilts are good, but leave the top of you exposed and in need of other insulating solutions. The 360 wraps the person AND the hammock inside a one zip cocoon. So no body weight to compress the sleeping bag and no cold butt syndrome. Works great. And the company is totally supportive of the customer. Read more

I have read all the reviews and personally use the bag 12 nights. I-am 6’0” and weight 250. I can zip it up all the way, snug but still comfortable. Sleep down to 38 degree in Arkansas. Most of the time i leave it zip-about 2/3 and use a inferno EOS as a top quilt when it would be less than 40-45. I sleep in ice breaker mid weight merino wool top and bottom.It does perform as state if you use it with in the manufacture suggestions. A fly over the top is also helpful to cut wind. Its good quality overall and is great for spring summer and fall. Its not a winter bag. Kids and a women, do really well with it. Plan on getting two more for the family for the ozark highlands trail sections next week and through warmer weekend this winter. Be reasonable about your cold tolerance and sleep comfort and most will be fine Read more

We combined this with a Get Out Gear down camping blanket to use as a top quilt and the combination has worked well at temperatures down to 40F, wearing just a base layer at night. The Thermoquilt and top quilt weigh right at 3 pounds total. The Thermaquilt does a good job as a wind sock, and in moderate temperatures would work well by itself. It’s large enough that it will fill in around you and not leave excessive air space, at least with our ENO single hammocks. The 40 degree F rating is realistically a survival rating more than a comfort rating unless you are fully dressed and/or using a puffy jacket. However, it can also be left zipped and doubled up under the hammock as an under quilt while using a heavier top quilt or sleeping bag for colder temps down into the 20F range. Read more

A good product with no issues others have mentioned. A little slim for a large adult when zipped up but will definitely be used with the kids. A good option to lighten your pack if you don’t think temps will be really low. We plan on using it on an upcoming trip, I’ll just use it as an underquilt. Read more

If you intend to use this as a hammock over/under quilt that zips up like they show you too. You will be sadly disappointed if your over 4 foot tall. There is no way to use this effectively if your not tiny. The shock cord and tightening cord for the foot and head of it are thin and ineffective. They are also poorly sewn into the thing and rip out with ease. The fill is thin and sparse. I don't understand got they got a 40 degree rating on this thing. For kids this is great, my 3 foot tall son fit great and slept great all night. Read more

First the pros: Thermaquilt did provide the insulation to prevent "cold butt" and the cocoon styling provided comfortable warmth on a 40 degree night with just wearing lightweight lounge pants and a t'shirt with a lightweight blanket. Didn't feel a need to put up bug net this site wasn't really buggy and planned on sleeping within the cocoon. Attaching was easy after video review however probably could have done without. Now for the cons: Didn't inspect before trip but at set up discovered stitching not complete at one spot..appears sewing machine ran out of thread. Zipper is ok but must be careful of catching material as zippering the material is very thin and I'm sure if caught would result in a tear had to carefully zip and unzip to prevent snagging. Material not a sturdy parachute material much thinner than hammock material. Overall: Materials very thin lightweight perfect for backpacking. Sturdiness will be determined overtime. It provided the warmth expected and would maybe perform at lower temps with a sleeping bag however the insulation fiber is very thin. Looks very nice at site on hammock zipped up during day gives a nice neat appearance. Feel compared to a regular under quilt it's 360 coverage it's performance is a great idea but for the thinness of the material, the zipper snagging and the poor quality control the price may be a little too high so value is lacking a little. Maybe $40-$50 for the great design idea, at the price paid expected a material a little heavier weight, a slighter denser fiber fill and better quality control. Longevity performance we will see overtime I will update in the future. Read more
