Backpacking Background
I have done a lot of hiking over the years but now carry a hammock and gear for over night stays of one to two nights. I normally carry approximately 35 lb (16 kg) which includes food and water. My trips are usually between one to two days duration mainly over weekends. I hike all seasons with winter temperatures ranging from 39 F (4 C) to 64 F (18 C) including periods of heavy rain at times to summer conditions with the temperature ranging from 68 F (20 C) to 95 F (35 C) and very dry.
Testing Locations
Bibbulmun Track: Sea level to 1,920 ft (585 m). Within this region I backpack along old forestry roads, sandy tracks, and purpose built walking tracks. The south-west of Western Australia allows for hiking and backpacking from coastal plains to forested ranges. I hike in varying conditions from forestry tracks, to sandy tracks to single purpose walking trails, from rock hopping, to beach walking to completely off-track through open and dense bush country.
Testing Conditions
It is now toward the end of our winter. Though we are still experiencing some unseasonably warm days, and yet some mornings with lows of 50 F (10 C) and highs of 68 F (20 C). In another few months it will be middle of summer and the heat will set in. Daytime temperatures will range during the testing period, from a minimum of  57 F (14 C) to 100 F (38 C). The average rainfall for the next few months is, 1 3/8 in (35 mm).

Description
The Nano-7 is an extremely light weight hammock designed for hiking, camping or just lounging around. It is made from lightweight rip-stop nylon and stuffs down to the size of a softball.
The Nano is a typical gathered end hammock. At each end of the hammock there are channels sewn into the end and a carabineer passes through the channel. Rope is then attached to the carabineer and on to a tree or post.
The long sides of the hammock are rolled hemmed with very nice stitching all the way along. The ends with the channels have been folded over once and tripled stitched to add strength
.
Inside the stuff sack is a care label stating the safe weight limit of the Nano plus how to wash it. Hand wash and hang to dry. It has four warnings about not smoking in the hammock, do not wear shoes, no knives and don’t go over the weight load of 300 lb (136 kg)

Features
The Nano is a straight forward, light weight hammock. The stuff sack is sewn onto one of the side hems near the centre. This serves two purposes, one is to store items in while hanging and the other is to stuff the hammock into while not in use.
The stuff sack has a neat little knot or perhaps a wrap of cord that is around the cord coming from the sack. To open or close the sack I just have to slide this knot along the cord. It is like a plastic cord lock in use.

 



 

Instructions
The instructions for using the hammock are printed on a swing tag attached to the stuff sack and are very straight forward. The Nano does not come with any rope but it is available at the Grand Trunk website.
There I could buy a hammock hanging kit for US$10.00 but I had been to a boating store and bought myself some cord that I will use. I noticed that the carabineers are not stamped with a weight load rating on them as are the climbing carabineers I have, but the website states that they are “High-Strength Carabineers”. I will have to wait and see how they perform. The tag also tells how to use the hammock hanging kit.

First impressions
This hammock feels very light, very soft and looks like it will be nice to use. The stitching around the hammock is very good. I am a bit apprehensive about the carabineers but I hope they do not let me down. I set the Nano up along side one of my DIY hammocks to check the size difference and to setup the ridgeline. The ridgeline I will use on this hammock will run from one carabineer to the other over the top of the hammock. This is used to set the amount of sag in the hammock body and ensures that every time I set up the hammock the sag is the same.
I had to retie the ridgeline a few times to get it just as I like but now it is quite comfortable. I am able to lie on the diagonal in the hammock which means my back is nice and flat and not shaped like a banana. I have used the hammock overnight the other night and it felt nice, but you will have to come back in about two months to read more of that night and others in my field report.

Field Report
November 17th 2009

I have now used this hammock on three occasions where I have slept in it overnight. The first was at my home where I have a pole set into the ground and with the help of a nearby tree I can test any hammocks I have and any gear I have made. I am a firm believer in testing any critical gear at home before heading out to the bush. The last thing I want is a cord to break or a hammock to fail.
I used the hammock one night in the hills of Perth near Mundaring. I had seen a spot on Google Earth that looked interesting and was only about 1.25 miles (2 km) off the nearest track. I headed out along the track to a point where I had to turn East through the bush and then bush bash off track until I found the spot.
The third time was one weekend when I went down to the Bibbulmun track, I now volunteer to maintain the section of trail plus the shelter at White Horse Hills. I hiked in about about 9.5 miles (15 km) from the car and set up camp for the night, then hiked back out in the morning.

I found the hammock to be shorter and narrower than I am used to but this has not stopped me from having a good nights sleep in it. The main issue I have had is my feet coming out of the hammock at night when I am sleeping. The first night I set it up I had it set too level, setting the hammock too level causes the torso to slide down in the hammock. Because of the weight of a torso verses the legs gravity will pull the torso down and this causes the legs to slide up in the hammock.
A hammock should really be set with the leg end higher to help overcome this sliding. The first night I awoke and my feet were quite a way out and I had to reposition myself and go back to sleep. The next two times I made sure to get the foot end higher but it is still not enough as yet because I still had a little trouble at White Horse shelter.
Setup could not be easier. I am using a thin light weight cord now for a suspension system and the whole thing minus the tree webbing fits into the stuff sack. I was using a heavier cord but it was a pain to get it all in the sack. Now it is a lot better but I am going to change it again soon for a smaller, lighter cord.
To setup I just open the stuff sack and pull out one end of the cord, tie that off on one of the webbings. Then slowly pull the hammock out as I walk to the other tree, taking care not to let the hammock snag on anything. Packing away is just a reverse of the setup. Easy Peasy.

At White Horse Hills.
The hammock is working out just fine, I have another well known brand of hammock at home plus a couple of ones that I have made myself. This hammock is by far the best one for me. I am lucky that I live in a place where bugs are not a huge problem or maybe they just don't like me. Over the years I have never really been bothered by bugs, and so this hammock without a bug net is just right. I like to feel the breeze on my face and be able to look out at the sunrise.
A funny thing did happen one night in Mundaring and I put it down to the hammock being quite narrow. I had just woke and got up to take care of a nature call and got back into the left side of the hammock and promptly fell out of the right side. Lucky for me I was not too far up in the air. My DIY hammocks are very wide on the sides and I have never had this trouble before. So from that night on I am very careful getting into and out of it.

One other thing that I will change with it is the carabiner at each end. When setting up the hammock at White Horse Hills campsite and as I was putting my Yeti under quilt in place I had a problem. The Yeti has elastic bungee cords running the length of it and fixes to each end of the hammock by the suspension lines. So I had just clipped the Yeti on when one of the bungee cords slipped through the gate on the carabiner and went in next to the hammock fabric by the channel. I opened the gate to remove the cord but as I did the fabric unfurled from the carabiner and I ended up with a big mess. I was worried about the gate pinching the fabric and putting a hole in it, so there I was holding the hammock off the ground, the gate open and all the while fighting the tension of the Yeti. After that night I decided to do away with the carabiner and change my suspension system.

The hammock itself does not show any signs of wear at all and I must go back and check the care label and give it a wash before I head out again. I'll report back in my long term report about that. I have another couple of nights planned end of this month plus I have a friend who is new to hiking and I have promised to take him out for a day hike. I'll take a small hydration pack with me and use the hammock at lunch time to rest.

Likes:
The small pack size.
The very light weight.

Dislikes:
If I have to pick, it would be the carabiner.
The small stuff sack could also be a little bigger.
Please bookmark this page and come back in about two months for my long term report
