Backpacking Background
I am an semi ultra-light backpacker, but I do not go to the extremes. I always attempt bring the necessities but cut down on weight in other ways. I also feel strongly that backpackers should always have good food. I have camped all my life and backpacked regularly for 3 years. I backpack year round but not so often in the winter months with snow. I also participate in other activities such as adventure racing, kayaking, and caving.

Field Report

I have used this compression sack on 4 trips with a total 10 nights in the past 2 months. This included a 4 night trip.  On these trips I was able to use the stuff sack to compress my tent (not the poles) and sleeping bag, clothes, and my food. I used the sack to compress my sleeping bag and tent during the 4 night hike. I compressed both my tent and sleeping bag together because I have the large compression sack which is rather big and just putting my sleeping bag in the stuff sack the sack would compress as much as it can (the straps on the sides were pulled all the way) and the sleeping bag was still not as compressed as it could have been, so I added my tent in there also so I could compress more. I could have added even more stuff such as my clothes because the large has that much room. I did wish that the bag was smaller so I didn't need to add so much to the bag to make it so it would compress contents more; however, this is not the a problem with the sack, I should have asked for a medium. The compression sack compressed my sleeping bag and tent together so that the sack was about 5in (13 cm) high with a diameter of 9.5 in (24cm). What I didn't like is that it got the sack flat it was still big across the diameter. This made it fairly awkward to pack at the bottom of my backpack. Again this might be a problem with just the large and the smaller sizes having smaller diameters making them more efficient to pack. However, if I was to change the dimensions of the large to keep the same volume I would make it taller with a shorter diameter.

I also carried my clothes in this stuff sack on a couple of my trips, one being a 3 night 4 day trip. There was chance of rain and cold nights on this trip so I packed rain gear and long underwear along with the rest of my clothes. I folded the clothes and stacked them in the stuff sack. This was again very little for the stuff sack to hold and compress fully. If the diameter was smaller and was taller instead I think that the clothes could have been able to be compress the clothes better. I also used this stuff sack as a pillow on these trips. It worked quite well and I am sure I will always use it as a pillow. This is when the larger diameter was better as it made the pillow flatter but bigger.

I also used this stuff sack to store my food in while backpacking in bear country. Food doesn't compress much at all so this compression sack was just being used as a sack on this trip; however, I did tighten the straps down so that there was no spare room in the bag for the food to move around in. This was helpful so that I could put dinner on the top in the morning and it was still on top in the evening when I wanted to get to it. However, the last day when there wasn't much food in it the bag couldn't get small enough to hold the food together tightly, but this wasn't a problem for me since it was the last day. The bag also was easily bear hanged using the strap on the bottom of the sack to tie the rope (parachute cord) to.

My stuff sack has yet to see the rain yet; however, it has seen my shower. When this stuff sack has enough stuff in it so it can be compressed tightly it is very waterproof. It didn't leak through the top nor at the seams something. This is something I liked very much.

Operating this bag takes some getting used to. The straps (being attached to the lid) can easily get tangled. In daylight it only takes a minute to untangle them; however, I found it nearly impossible to do it without a night light when it was really dark (I could barely see the bag, it was all by feel). With a light they it can be untangled quickly. If the bags straps are not tangled then it can easily be opened and closed in the dark

I also used the bag while traveling to compress a week's worth of underwear and socks. This was very helpful in packing and I will use the stuff sack again like this.
