Game changer

Evolution 20 Down
I have done a lot of camping, both tent and hammock camping. I have been searching for the perfect sleep while camping and until now everything has been coming up short. I was just in Hico, West Virginia for 4 nights of camping. It was in the 50s the 1st night and then down into the low 30s last three of the nights. This hammock was perfect. Unzipped I was comfortable the first night and zipped up I never felt the cold the other 3 nights. I was as comfortable as sleeping in a bed in a climate controlled house. I am so happy I found out about this hammock, it is the best piece of camping gear I have ever had.

Grand Trunk service and quality

I frost heard about Grand Trunk from my brother who camps with a hammock constantly. Always telling me how great it is. I’ve done it this spring and absolutely love it. So when he told me about the quality of Grand Trunk I decided to go on their website to check out their gear. I was impressed. I bought the Evo 20 which not only did the send it fast it got to my house faster than expected. I only got to look at the hammock for a bit and will be using it the first time very soon and I’m excited. After just looking at it and feeling the hammock it definitely is quality. Not only that, they had a great discount for military members like myself that really shows this company cares for its military. They were great with updates too with emails and seemed very confident on all products. Not only that, but their lifetime warranties are worth the money. I even ended up buying three more products and plan to buy more. I’ve been nothing but impressed by Grand Trunk and will be using their products for my YouTube videos and talking about how great they are even though I’m not sponsored. Love this company!

I’ve been a hammock camper for over a decade. I’ve tried all manner of hammocks, bags, over quilts, under quilts, etc…The Evolution 20 is just a massive leap forward in hammock camping. Its so compact, and simple. No more struggle with orienting your bag, or getting in and out in the middle of the night. The bag doesnt move! Just a fantastic piece of kit, and worth every penny.

I took this hammock to Havasupi and during my trip it rained, my rain cover had gotten blown over and even though it had gotten a slightly wet it kept most of the rain out and I had no issues sleeping in it, it kept me very warm. 10/10 would recommend the only test left is the test of time to see how long it will hold up but if you want a warm, sturdy hammock that makes it look like no one’s in it and stays dry even if a little rain gets on it, this is the one for you. Little bonus, I didn’t need netting to keep the bugs out because the flaps covered my face and it wasn’t suffocating although that was because I forgot it not so much because I didn’t want it. Use it however you want but you won’t be disappointed if you get it.
