ZPacks Sleeping Bag Review
Pam and I love cycle touring, and if you check out our gear list you know that we hate lugging extra weight. Our previous sleeping bags collectively were weighing in at around 4 lbs (1.8kg) each. Considering that our total gear weight was about 50 lbs, the bags accounted for almost 10% of the weight we were carrying. After some research I decided to try to reduce that weight and try out the Zpacks ultralight sleeping bags.
About the company: Zpacks is the brain child of an avid ultralightweight hiker, and they manufacture most of their products in Florida and are currently some of the leaders in the ultralight hiking market. Since Pam and I try to support people who provide good products and pay their employees well so it is easy to support Zpacks.
Spec: Zpacks sleeping bags are available in four temperature varieties: 40F, 30F, 20F, 10F. They come in 5 different sizes based on your height, and 2 widths based on your girth. Either 900 fill or 850 fill water resistant down is available. The outer and inner fabrics are Pertex GL, a durable, lightweight material.
About the bag: The fabric feels similar to other tech materials: smooth, slippery, and thin. This doesn’t bother me at all. Most of the time I do use a silk liner, but that is mainly to keep the bag clean or to sleep on top of the bag during warm nights. The bags are designed to be slept in with the zipper on the ground underneath your back to reduce drafts. While the zipper is small and doesn’t bother me laying on it, I tend to toss and turn all night so I added an optional draft tube to prevent drafts as I do my nightly roll overs.
The bag is shaped so that it is larger at the top of the bag and tapers down to a small foot area. The whole idea is to minimize the space inside the bag which you have to heat up; this will keep you warmer with less extra material and therefore less extra weight. The zipper extends to about ¾ down the length of the bag which is plenty for climbing in and out.
One of the most amazing things about this sleeping bag is how much you can compress it down. Fully compressed it is downright tiny and as soon as you pull it out of the bag it starts inflating back up to full size. With a little fluffing it is perfect every night. The second amazing thing is Matt’s bag only weighs ONE pound. A one pound, 20F rated bag has kept Matt plenty warm even on a 15F night.
Durability: Initially I was very concerned about how the bag would hold up to continuous use on a bicycle tour. In hindsight this is probably a silly worry as a bicycle tour is not any more taxing on equipment than 3 months of hiking which is what this bag was designed for. Through 45 days of bicycle touring on the southern tier, this bag performed like a champ, and continues to perform as expected.
Overview: The Zpacks sleeping bag comes highly recommended by me. The weight and comfort are amazing. This is a great place to spend a little extra money to ensure that you get a warm comfortable night’s sleep and slash a few pounds that you have to carry around on a tour.
