The TETON Sports Outfitter -35 Degree Sleeping Bag is designed for those who need serious warmth in extremely cold conditions, with a temperature rating down to -35°F. It uses SuperLoft Elite hollow fiber insulation in a double-layer design to trap heat effectively, making it suitable for winter camping, hunting, or any cold weather adventure. The sleeping bag has a rugged canvas shell that’s water-resistant and built to last through many trips, paired with a soft cotton flannel liner for comfort. Its rectangular shape offers plenty of room and is great for people who prefer extra space to move around while sleeping.

This construction comes with a trade-off in weight and packability—it weighs about 20 pounds and is bulkier than many modern lightweight sleeping bags, so it’s best suited for car camping or situations where carrying heavy gear is not a concern. The zipper is sturdy and placed on the right side, providing ease of use and durability. While the bag is compressible to an extent, it won’t pack down as small as lighter synthetic or down bags. For those who prioritize durability, warmth, and comfort over ultralight portability, this sleeping bag offers a solid choice with tough materials and a lifetime warranty that adds confidence for long-term use, although those looking for lightweight, highly packable options might want to consider other models.

The dual-direction zippers allow for easy access and ventilation, enhancing user comfort.

Some users might find the bag a bit tight, especially if they prefer more room to move around.

This sleeping bag is ideal for campers and backpackers who prioritize sustainability and decent performance without breaking the bank.
