Let’s take a closer look at this synthetic sleeping bag:
The Slumberjack Latitude 40 Degree Synthetic Sleeping Bag features a temperature rating of 40 degrees Fahrenheit. Although it’s rated as a warm weather sleeping bag, it still works well in 30-degree temperatures. When you first jump in, you might feel a bit chilly in colder temperatures, however once your body warms this puppy up, you’ll be just fine. Just don’t take it to bag Mt. Everest.
Warm and Comfortable
A high-quality sleeping bag has to be warm and comfortable, right? This one is the perfect cozy balance of comfy and toasty—there’s even a reversible, adjustable hood for extra comfort and warmth.
Ok, it does feature a zipper, which is usually a no-no for the anti-drafters, but this Slumberjack bag keeps the drafties out nicely anyways, with a draft tube that prevents heat loss and otherwise keeps cold weather out. The zipper is a high-quality design to keep it functioning for the life of the bag, with a coveted anti-snag feature sewn along the zipper as well as the draft tube.
(I noticed zipper complaints in other customer reviews, but so far the zipper works smoothly for me each time I’ve taken it for a spin.)
Velcro Flap Issue
One of the few negatives about this mummy sleeping bag is the semi-rigid Velcro flap found at the top of the zipper. The flap is meant to keep the bag tightly closed when fully zipped for additional warmth and comfort, which is fine and dandy. However, if keeping the bag partially open at the top, the seam at the flap edge proves rough and irritating, even against clothing. Cutting the irritating portion of the flap off the bag is the best way around this issue.
Mummy Shape: Either You Love It Or You Don’t
This and other mummy bags present issues for those who don’t like to feel confined as they sleep. Mummy-shaped bags are generally detested by side sleepers for this reason, as well as by tummy-snoozers. Whether you use the hood or you don’t, a good night’s rest in your bag often comes down to shape preference. There’s a little bit of middle ground here, as the bag’s trapezoidal foot-box feature allows the feet to remain in a natural position, so you’re not feeling like you’re back in grade-school with your shoelaces tied together by the class bully.
Recommendation: The “Non-Extreme Camper”
For the camper who likes to toss stuff in the pickup, head out, and enjoy the summery outdoors, the Slumberjack Latitude 40 Degree Synthetic bag is great, especially for the price. If camping in 30-degree and lower weather, or long backpacking trips are your thing, there are warmer and lighter options out there. Overall, feel confident snagging this bag for casual, infrequent use. It holds up, provides a warm and comfortable night of rest, and keeps those pesky drafts at bay.
