The outer shell uses a 30-denier polyester shell with an inner liner made from 20-denier recycled polyester taffeta. It does a good job of keeping out the moisture that is usually trapped inside the tent, which I discovered after one very rough night of testing. The filling is what Nemo calls Zerofiber insulation, which is made from 100 percent postconsumer recycled fiber content. Zerofiber is extremely compact – this is the most compact and compact bag I’ve tried in a while – and still retains warmth even when wet.
What I love about this bag, and almost all of Nemo’s bags, is the high cut through the gut to the knees. Like the Therm-a-Rest Questar above, this bag is almost a hybrid of a mom’s bag and your dad’s old 1970s square sleeping bag. Meaning that this bag is bulky. The downside is that there is more room for your body to heat up, but as someone who sleeps warm, I’ll take the extra room.

How to Choose the Best Sleeping Bag
A sleeping bag is one of the most expensive camping items you can buy. If none of your choices appeal to you, here are some tips.
How Can You Use Your Sleeping Bag?
Are you car camping? Hiking the PCT? Did you go out all night in the August heat? Planning a winter ski trip to the Karakoram Himalayas? Which sleeping bag is right for you depends on how you will use it, especially the temperature you want to camp or backpack, and how you sleep—hot, cold, in between.
Unfortunately, there is no good sleeping bag that works for all seasons. If you are going through a lot of conditions on your camping trip, I would consider two bags. Find one that’s great for keeping cool and an inexpensive, lightweight backpack for summer use.
As with most outdoor products, you’ll pay more for the lighter stuff, so if you don’t need it because, for example, you’re camping, don’t pay extra for a lighter bag. Maybe don’t even pay for the low price. Synthetic bags are often the best budget sleeping option for those camping in the heat.
Likewise, if you’re a summer hiker, doing the Appalachian Trail in sections, you don’t need a 0-degree bag. Find out how to use it and find the sleeping bag that’s right for you. Also, take the heat level with a grain of salt. Everyone sleeps differently. I always sleep warm, which means I don’t need a 0 degree bag in any way but the worst. My friend Adrienne So is very different and uses a 0-degree bag in 40-degree weather. None of us are “right,” we’ve just learned to buy the way we sleep.
Types of Sleeping Bag Insulation
There are two types of padding used in today’s sleeping bags, down and synthetic fibers. The floor is coming especially geese and ducks. Synthetics range from nylon to polyester. Melting works by creating air pockets, either through a feather design or a synthetic fiber design. These layers of air trap your body’s heat, keep it close, and warm. The higher the altitude – the more air pockets – the hotter you are and the lower the temperature of the sleeping bag.
In most cases, a sleeping bag is the best choice. It’s lighter for its weight, packs smaller, and is lighter. Where it fails is when it is wet. Moisture is often useless – all the bags that trap heat are gone. Synthetics, on the other hand, retain more heat when wet. No one wants to sleep in a wet sleeping bag, but if you think it’s possible, the synthetic method is the way to go.
