0F vs 20F Sleeping Bag Specs

Temperature Rating

Edge: TETON Sports Deer Hunter 0°F Canvas Bag

The TETON Sports Deer Hunter is rated for 0°F, making it suitable for cold weather and winter camping conditions. The Kelty Doublewide carries a 20°F rating, which is better for three-season use in milder climates. If you plan to camp in freezing temperatures or high-altitude environments, the 0°F rating provides a necessary safety margin. For spring or fall trips where nights are cool but not freezing, the 20°F option is sufficient. Your choice depends entirely on the lowest temperatures you expect to encounter during your outdoor adventures.

Capacity and Size

Edge: Kelty Doublewide 20F Sleeping Bag

The TETON Sports Deer Hunter is a single-person bag measuring 90 inches long and 39 inches wide. In contrast, the Kelty Doublewide is designed for two people, offering 64 inches of shoulder width and an 84-inch length. This makes the Kelty significantly wider, allowing two adults to sleep comfortably side by side. The TETON bag is narrower, intended for one person who needs extra length. If you are camping with a partner, the doublewide saves space and weight by combining two sleepers into one unit. For solo travelers, the single bag offers a more snug fit.

Weight

Edge: TETON Sports Deer Hunter 0°F Canvas Bag

Portability matters when you are hiking to a remote campsite. The TETON Sports Deer Hunter weighs 8.5 pounds. The Kelty Doublewide is slightly heavier at 9 pounds. Both bags are quite heavy for backpacking, but the difference is minimal. You will carry nearly the same load regardless of which you choose. The TETON bag is lighter by half a pound, which might be a small advantage if every ounce counts. However, the Kelty bag supports two people, so the weight per person is lower. For car camping, neither weight is a significant burden.

Shell and Lining Materials

Edge: TETON Sports Deer Hunter 0°F Canvas Bag

Durability and comfort vary by material. The TETON bag features a tough canvas shell and a poly-flannel lining. Canvas is known for its ruggedness and resistance to wear, making it ideal for rough outdoor use. The Kelty bag uses a synthetic insulation with a 75D poly Taffeta lining. This fabric is often smoother and softer against the skin. The canvas shell on the TETON bag may feel stiffer but offers superior protection against abrasion. Your preference depends on whether you prioritize long-term durability or immediate softness and comfort.

Intended Use

Edge: Tie

The TETON Sports Deer Hunter is explicitly labeled for hunting and camping, with a focus on cold weather performance. Its design supports stationary activities where staying warm in freezing conditions is critical. The Kelty Doublewide is marketed for couples and frequent campers, emphasizing comfort and social sleeping. It is designed for shared use in car camping scenarios. If your primary activity is hunting in cold environments, the TETON bag is the specialized tool. If you are camping with a partner in mild weather, the Kelty bag offers better social utility and space.
