Evolution 20 Synthetic Sleeping Bag Hammock

Went on scouting trip with grandson used mine he used his great product, no rocks sticking you in the back or roots laying on , under quilt is great got down to 47 was warm thank you . Made great time for us easy set up .

I’ve only used the hammock in 40 degree temps but it kept me incredibly warm. The UQ portion might be a little tight but it doesn’t seem to affect the performance. I only wish it came in a color other than teal.

I was looking to upgrade my hammock setup and this ticked all the boxes. Used it the last 3 weekends in single digit temps at night....was perfectly warm and didn't feel cramped...Hammock has plenty of room to lay flat and get a great sleep.

So long story short, the free international shipping took forever. Like 1 month forever. And import taxes were freaking expensive, like over 100$! But that is because of Norway.
The product is very much as described though! It feels like quality and I was positively surprised by the ability to sleep asymmetrical for a flat lay, that is awesome! Especially since I'm a really big guy. I've had it out two times since it arrives and both night got down to about -6*C. It wasn't overly warm but this was about pushing the product to its limit and it really delivered. I really had a good night sleep in this. I also purchased the siesta hammock pillow and that worked great with this hammock.

So thank you Grand Trunk for this great product and I hope I never have to use that lifetime guarantee.

Decided to bring this snow camping as a first trial. None of the people I was with believed me when I said I was going to spend the night in this without a sleeping bag. They all chose to sleep in their cars. It got to around -5*C over night and snowed 4inches. I ended up being the warmest out of anyone, without a single ache or pain.
I can't praise this hammock enough, it's the quiver killer for camping.
Ditch your ground mat, sleeping pad, sleeping bag and tent for this beauty and the abigo rainfall.

I love this hammock, but its not quite a 20⁰ rating like it says. The down version is (i have that as well) but I need to add a light sleeping bag inside this one if below 40⁰.

I camp a LOT, like 8 months of the year while I work seasonally. I got this hammock because its starting to get cold up here, & it came with the top/bottom quilt built in. From the first time I layed down in it I loved it. Its extremely comfortable, & warm, very easy to lay flat, spread out & stretch. I slept better in this thing than I do in a bed. I did have a defect in the sitching, which would have ripped at some point, but they honored their warranty with 0 hassle. I even got to keep the old hammock, which now is perfectly fine to use as a sleeping bag. Highly recommend this company! If I could give a higher rating I totally would!

Ive gotten to use it once, it was approx 30 to 28 degrees. It worked wonderful in my experience. Im looking forward to going out in most seasons with this

Awesome!! The all-in-one design of this hammock is a real game changer for me. No more bulky under/over quilts, just warm and cozy sways.

I camped in just a couple of nights so far. The range of tempreratures ranged from 32F to low 40's. Surprisingly, it felt much warmer with lower temps, because the himidity dropped. Which hight humidity in low 40's I had to use nalgine bottle, because my feet wouldn't keep warm on their own. I find there is too much space for feet that makes it harder to maitain the heat. Another minus is lack of any storage space. Even side pocket in the construction would be extemely helpful.

It’s not a terrible insulated sleeping bag, but it’s not a 20 degree bag. I had to use a 40 degree underquilt to be comfortable below 30 degrees. One star for a rating that could get you killed.

First things first, I tore open my package with glee at my fantastic new purchase, and pulled out this beautiful beast. I inspected it opened it, found a nice mesh carry bag that comes with it, all nicely made of course, whilst outside its a brisk 40 with cold wind gusts here and there. (I know what you're thinking, a perfect time to set up a hammock.) So I do. I crawl inside, zip it up and take a nap while the wind blows and whips and whirls. I slept like a baby. So I take it back inside and roll it up stuff it in its compression sack it comes in and to my dismay the compression sack immediately failed at the seams the second i put pressure on the straps. What a bummer.
Besides the compression sack, this item is without a doubt going to Change the way I camp. Would have given 5 stars, but i needed that compression bag to fit it nicely on the bottom of my pack, and I'm bummed to have to find another. And so close to my trip.

Grand trunk, I want to love you. Put some oomph in your compression sacks. The hammock is everything i wanted it to be and more. The bag should be too.

I've used other hammocks as camping bed many times in the past. Usually for our Alberta summers the temps get down to 10C, past that the lack of insulation from all sides makes them usually too chilly without an extensive set up that tents start looking preferred.

Two nights ago I trialled this one in -8C, light wind late November night and was very surprised. I'm 205lbs 5'11, with my insulated coveralls on I was just under those sweating warm temps. Perfectly cozy. Although there are no mosquitos I suspect zipped up with a bug net headpiece it would be completely bug proof as well for other seaons, the underquilt is too thick to be bitten through unlike a stand alone regular hammock.

Has enough room inside for a little angled flat laying, and a blanket but probably not for two people, although might be possible with two smaller folks than myself.

I was impressed enough I bought the down evo as well to keep in my truck full time as aside from anything past -10c I'd say this could handle it with clothes on in a worst case scenario.

Also, it's not stated but I see no reason this couldn't be used as a sleeping bag/blanket if a tent was around with open space.

Really just a versatile piece of gear that I have no regrets owning two of.

Did an overnight camp in the Pacific Northwest it rained hard I had my hammock tarp over my new Grand Trunk .I was so surprised how warm I was when temperatures got down to round 36°.. Plus, this hammock is very easy to set up, to get in and out of. I'm very happy with this hammock.

I bought the synthetic 20 mostly to save cost and evaluate the quality of product before spending more on the lighter down version.

I’m very impressed. I have hammocks and under quilts and even other hammocks with built in under quilts that I have spent thousands of dollars on. This hammock will now be my simple go to hammock for anything over freezing weather.

What I really like is that I can point friends to this to get into hammock camping. It’s a small price and a single item that doesn’t take research and a learning curve to figure out under quilts and top quilts and have lengthy shopping list from many different companies.

I would also recommend this to anyone that just needs a decent sleeping bag. I tried it on the ground and it works great for that, too! That really simplifies a packout and a one for all situations for a really good price!

I only gave it four stars because every hammock of any quality should include a structural ridge line especially an introductory hammock like this one. Even an option for one would be better. I put one on and set it to around 88% and it takes this setup from great to awesome.

I recently had the pleasure of using a synthetic sleeping bag hammock for the first time during a cool October weekend, and I couldn't be happier with the experience.
This synthetic sleeping bag hammock exceeded my expectations in every way. The moment I set it up, I was impressed with its build quality and design. It was easy to hang, I have my own tree saver straps.

As I settled into the hammock, I immediately noticed how comfortable and cozy it was. The synthetic insulation provided excellent warmth, keeping me snug on those chilly October nights. I didn't need an additional sleeping bag; this hammock was enough to keep me warm.

The quality of the materials used is evident in every aspect of this hammock. It withstood a weekend of use without any signs of wear and tear. It's clear that this product is built to last.

Overall, my first experience with this synthetic sleeping bag hammock was exceptional. It kept me warm, comfortable, and provided hours of relaxation. If you're looking for a versatile and high-quality sleeping solution for your outdoor adventures, I highly recommend this hammock. It's worth every penny, and I can't wait to use it again on my next camping trip.

Comfortable, warm, not small but definitely worth packing if you’re not hiking too far. I have only used this around 40 degrees, but it kept me warm. I would definitely recommend.

I am happy with my "combo" hammock kit and will do my best to wear it out.

I recently took this bag/Hammock on a pack in trip to cloud Peak in the Wyoming Big Horn Mountains. The bag kept me warm at night and was actually really comfortable especially once I added a pad. I would recommend the set up.

Having purchased two Grand Trunk hammocks and hammock frame, I found them to all work perfectly, however, the East coast of Scotland is notorious for its cool onshore breezes even in "summer", making additional insulation essential. After five years of using travel rugs, travel cushions and sleeping bags with my GT hammocks, I discovered that Grand Trunk had designed a sleeping bag hammock and hammock pillow so I ordered both. After paying £112 in duty, due to the lack of a USA-UK trade agreement, the box was duly delivered after a transit of about 14 days which was pretty good. The items were safely packaged in the transit box and the sleeping bag hammock was in its own transit pack with cinch-able plastic buckles but there was also a mesh bag to allow the item to breathe when not on the move - a very useful inclusion. Furthermore, the item came with two snap carabineers which could have been clipped directly to my GT hammock frame, but I used some GT hammock straps from an earlier purchase. The hammock pillow also arrived in an integral transit pouch and was easy to deploy to the correct position inside the hammock's hood. The sleeping bag hammock when opened out has a 'head end' and 'foot end' so work out which way you want to face before deploying the hammock. That done, I just sat inside the edge of the hammock and slid my legs into the zipped open sleeping bag, after a couple minutes I was toasty in ambient temperature of 15C, which is quite typical for a Scottish "summer" hereabouts! This sleeping bag hammock is perfect for daytime hammocking in cool temperate latitudes where sunny days are often accompanied by chilling winds; consequently, I can Highly Recommended this item for this type of location and purpose.

Love this hammock. Camped in 37 degree temperatures. Brought a blanket for extra warmth but didn’t need it at all. This hammock is warm and comfortable.

So first it was a Christmas present that got lost in the mail. Grand trunk pulled their magic and a replacement arrived before Christmas. The cold snap that came through ended up making me give it as an early present for my six year old. In his excitement I left my hammock and my five year olds hammock. So me, a six year old son and five year old daughter all slept in the hammock together. Was it a little I’m comfortable? Yes. But were we miserable? No. I was really impressed. The next night I went home and got the missing hammocks and under quilts. Much better sleep for one. It was a great purchase. Literally no complaints. Except I miss the attached stuff sack. The one it would need would be huge. But I miss the smaller normal on one some brands so I can put things in it for bed. Water battle. Glasses. Chapstick. Random stuff. That was the only thing I really wish would be added. I sew so I’ll sew one if my son lets me use it again. He loves it!

Here’s the 5th star!! I’ve hammock camped for years and always hated packing my 15-20° bag, underquilt, hammock, and straps. With this bad boy here I’ve been able to pack lighter AND be more comfortable. I can’t recommend this enough!! It’s absolutely wonderful and a must have, in my opinion. You will NOT be disappointed!!
