Camping doesn’t have to mean choosing between expensive or bulky gear. Whether you’re heading to a campground for the weekend, backpacking, or planning a road trip with some overnight stops, a lightweight mid-weather sleeping bag can provide comfort without overheating or being too chilly. Finding that balance between comfort, packability, and practicality without sacrificing cost or durability can seem daunting with so many options, but thankfully REI makes it easy. 

Designed for light backpacking or camping, the Kelty Mistral 40 Sleeping Bag is great for long trips or quick weekend getaways. Shoppers can get it for just $45 right now at REI, offering a great price for what you need, without spending extra for what you don’t.

Why do shoppers love it?

Designed for mild-weather trips, this bag focuses on the essentials with a lightweight design and synthetic insulation that helps keep you comfortable in 40-degree weather and above. A durable, 68-denier polyester taffeta shell and liner offer comfort, while the Cloudloft synthetic insulation provides warmth without adding unnecessary bulk. The mummy shape helps retain heat, making it a practical option for cooler weather, while it can also be unzipped to help let heat out on warmer nights. The built-in hood also keeps you comfortable on cooler nights, and adds a plush place to lay your head without a pillow. The natural-fit footbox offers extra room to move your feet, preventing the feeling of being overly restricted.

This sleeping bag also includes features that make camping easier. The anti-snag zippers make it easier to zip and unzip during the night, while the draft-locked zippers help block cool air from entering, and the offset quilted pattern reduces cold spots and lumps in the sleeping bag, helping the insulation stay evenly distributed throughout the night. Weighing just 2 pounds 12 ounces, it’s light enough to bring on backpacking trips without adding tons of excessive weight, and the included stuff sack helps compress it down for easier transport and packing.
