Kelty Mistral 40 Deg Sleeping Bag Review

Let’s Talk About Kelty Mistral 40 Deg Sleeping Bag

As an outdoor gear specialist, I’ve field-tested countless sleeping bags, from ultralight backpacking models to expedition-grade behemoths. The Kelty Mistral 40 Deg Sleeping Bag immediately caught my eye as a budget-friendly option that promises decent performance for warm-weather camping. Kelty, a brand synonymous with quality outdoor gear, aims to deliver comfort and packability in this sleeping bag, making it an attractive option for casual campers and budget-conscious adventurers.

I needed a lightweight and packable sleeping bag for summer camping trips where temperatures rarely dip below 50 degrees Fahrenheit. My old bag was bulky and overkill for such conditions, taking up valuable space in my pack. I was searching for a balance between comfort, portability, and affordability.

Upon unboxing, the Kelty Mistral 40 Deg Sleeping Bag felt surprisingly soft thanks to its polyester taffeta liner. The CloudLoft insulation felt reasonably lofty for a synthetic fill, and the overall construction seemed sturdy, although not as robust as higher-end models. The included stuff sack felt a bit flimsy, but functional.

Compared to the Marmot Nanowave 55 and the Coleman Sun Ridge 40, the Kelty Mistral 40 Deg Sleeping Bag felt slightly more comfortable and packable than the Coleman, but not quite as refined as the Marmot. I chose the Kelty primarily for its balance of features and price, hoping it would offer adequate warmth and comfort without breaking the bank.

Initially, I was cautiously optimistic about the Kelty Mistral 40 Deg Sleeping Bag. It seemed like a good value for the money, but I was eager to put it to the test in real-world conditions to see if it lived up to its claims.

Real-World Testing: Putting Kelty Mistral 40 Deg Sleeping Bag to the Test

First Use Experience

I tested the Kelty Mistral 40 Deg Sleeping Bag during a weekend camping trip in the Shenandoah National Park in late spring. Nighttime temperatures hovered around 45-50 degrees Fahrenheit with relatively low humidity. I slept in a tent on a standard sleeping pad.

The bag performed admirably in these conditions. It kept me comfortably warm throughout the night, and I didn’t experience any cold spots. The comfort hood was a welcome addition, providing extra warmth around my head and neck.

The bag was easy to get in and out of, and the anti-snag zipper design worked flawlessly. Packing it back into the stuff sack was a bit of a struggle, but manageable.

Extended Use & Reliability

After several weeks of use on various camping trips, the Kelty Mistral 40 Deg Sleeping Bag has held up well. There are no noticeable signs of wear and tear, and the insulation has retained its loft. The polyester taffeta shell and liner seem durable enough for casual use.

Cleaning the bag is relatively easy. A quick wipe-down with a damp cloth is usually sufficient to remove any dirt or stains. I’ve also machine-washed it on a gentle cycle and air-dried it without any issues.

Compared to my previous sleeping bag (a bulky down-filled model), the Kelty Mistral 40 Deg Sleeping Bag is significantly more convenient for warm-weather camping. It packs down smaller, dries faster, and requires less maintenance.
