design and durability


The Hyke and Byke Snowmass 0 Degree Down Sleeping Bag sleeping bag is a mummy shaped one. These Hyke and Byke bags help in maintaining body heat and will keep you warm through the night. Mummy shaped bags tend to be a little snug, though, so some people might not find them to be very comfortable. However, for hiking in freezing temperature, they are usually a good option.

This one also has a wide foot box, so you can move your feet around and not feel like they are stuck in a tiny space.

The outer shell is made of 400T 20 D ripstop nylon. The shell is water-resistant and quite durable. The filling is of duck down, and thus is very lightweight. The down feathers present in the filling form air clusters which help to retain heat. It has great insulation properties and you won’t find yourself freezing, even in low temperature.

To keep your head warm, the Hyke and Byke Snowmass comes with a hood which frames your face. The hood closes with drawstrings, so you can adjust it according to your own preference and comfort level. There are horizontal baffles as well, which prevent cold air from getting inside. The zipper is secured with a horizontal draft tube as well as Velcro.

The one negative point of this sleeping bag is that the zipper is not as excellent as the rest of the bag. It tends to get snagged in the nylon fabric, even if you are really careful.



size and dimension of hyke & byke

The sleeping bag comes in two sizes – regular and large. The regular one fits a person up to 6 feet one inch long, while the tall one can fit people who are up to 6 feet 6 inches in height. The regular one is 78 inches long. Its width is 2 inches at the level of the shoulders, 22 inches at the hips and 11 inches in the region of the toes.



The normal size sleeping bag weighs just 3.86 pounds, while the long weighs 4.24 pounds. So you can see that this sleeping bag is very lightweight and backpackers can take it with them with ease.

Considering that it is a winter bag and has a very adequate insulation, the weight becomes even more impressive. Not many winter sleeping bags are easy. The weight to warmth ratio, therefore, is very good.

My Test

buying hyke and byke

My first impression of the Hyke and Byke Snowmass bag: It’s really lightweight! The material seems really thin and light, but at the same time strangely strong. The sinch pocket also seems extremely thin, but I think it is accounts for easy.
My first night in my normal bed: The bag was warm, I did not sleep too hot in my room at room temperature.
I was curious to see how this bag would do in the open, considering that I did not overheat at room temperature.
My first night outdoors: It was 30 degrees Fahrenheit, a slight windchill, and I slept in my hammock. I had a Klymit V2 sleeping bag under me. During the night, the only reason that I would be cold was when my sleeping bag fell out of place, so what led to Windschauer from below. Now I’ve found out that it’s best to put your sleeping bag in your Hyke and Byke sleeping bag to prevent the pad from fiddling sideways in the hammock.



This Hyke and Byke price is at $ 149.99 on Amazon. They can find cheaper varieties on the market, but they are usually not as light or as high quality. Winter sleeping bags are usually priced higher than summer because they have more insulation and filling. They often cost more than $ 100.

This sleeping bag has the highest warmth-to-weight ratio, and hence has quite good value for money.




  • Very warm
  • Lightweight
  • Can be packed to a small size in its compression sack
  • Water-resistant, durable outer shell
  • Adequately distributed filling, so there will be no cold spots
  • Two sizes means that you can choose one which suits your height


  • Cheaper sleeping bags are available in the market
  • Cold can seep inside through the base of the sleeping bag, unless you use a sleeping pad. If you do decide to use a pad, it has to be bought separately.
  • Zipper tends to snag in the nylon fabric
  • It may get a little difficult to stuff the sleeping bag inside its compression sack.

This Hyke and Byke sleeping bag is designed for 0 degrees Fahrenheit. This is a mummy bag with a downward insulation. The outer shell is nylon ripstop and is water repellent. The inner lining is quite comfortable, although a sleeping bag is needed to make you perfect.

The Hyke and Byke sleeping bag weighs only 3.86 pounds. while the long weighs 4.14 lbs. This makes the sleeping bag very light, especially since it is a winter bag and therefore has a lot of filling. The bag can be compressed to a small size and fits into its own compression bag. You can then pack this compression bag with the sleeping bag in the backpack.

The bag is very durable, even if the zipper is not. The zipper tends to catch the fabric. The bag keeps you very warm, and there will be no cold spots all night long.

I would highly recommend this product. It is extremely lightweight, it folds down to a small easy to manage size, and it is exceptionally warm. I was worried at first i would tear the bag because the material is very thin, however, this sleeping bag is very durable.
