The NEMO Strato Loft 25 sleeping bag is about as close to sleeping on a twin bed as you can get in a car camping sleeping bag. Weighing 3 pounds and 4 ounces, the Strato Loft is too heavy for use as a backpacking sleeping bag, but it’s ideal for three-season car camping, especially for side sleepers or anyone who moves around a lot at night and can’t sleep in a mummy-bag-style straight jacket.
Technically speaking, the Strato Loft 25 is more of a quilt than a sleeping bag since it’s not insulated underneath. Instead, you need to slip a 25 inch sleeping pad into a compartment under the bag to use it. The compartment closes at the end with a zipper and has an opening at the top so you can pull your pad into it. This works best with NEMO’s 25L Cosmo inflatable sleeping pad, but not all 25 inch pads fit. For example, my Therm-a-Rest NeoAir Dream sleeping pad is too thick to fit into the Strato Loft 25’s pad sleeve, even though it’s the same thickness (4″) as the NEMO Cosmo 25L on paper.
The Strato Loft 25 also doesn’t have a mummy style hood although it is insulated and you can drape it over your head for added warmth. I like to bring my pillow from home car camping and slip it inside the hood, which holds it in place, with plenty of space for my head underneath.
Insulation and Heat Management
The NEMO Strato Loft 25 is insulated with 700 fill power down which has been treated with Downtek’s waterproof technology to resist getting wet. The top of the bag is sewn using a a box stitch pattern which keeps the down in place and prevents it from shifting, just like a sleeping quilt that you’d use at home.
Like many of NEMO’s other sleeping bags, the Strato Loft 25 comes with a blanket fold, which you can position between the top of the sleeping bag and your chest to prevent hot air from escaping from your bag in cold weather. It’s very similar to a draft collar that you find cold weather mummy sleeping bags, except it’s optional whether you use it or not. In warm weather, you can fold it over so that it lies on top your sleeping bag instead of on your chest, so hot air can escape.
The Strato Loft 25 also has two side zippers one on the right and one on the left of the bag that you can open at night to cool off as well. The zippers are two-way, so you can just open them next to your feet, or from the top down to cool off your torso. Both zipper tracks have down filled draft tubes which prevent cold air from leaking through the zippers onto you, and they’re lined inside with an extra strip of fabric that prevents snagging on the sleeping bag lining.
Waterproof Foot Box
The Strato Loft 25 has a waterproof/breathable foot box that repels tent condensation from wetting the end of your sleeping bag at night. If you’ve ever woken up with a wet sleeping bag in the morning where it’s rubbed against a tent wall, you can understand what a great feature this is. The interior fabric of the foot box is a waterproof breathable nylon which prevents the down in the bag from getting wet. The outside of the foot box is nylon coated with a DWR layer that will resist getting wet and can be wiped off in the morning with a cloth to help it dry.
I’ve been using the NEMO Strato Loft 25 sleeping bag for nearly a year and love sleeping in it on car camping trips. I move around a lot of night and it’s wide enough that I can sleep in many different positions without feeling trapped like I do in a narrow mummy bag. I also really like the venting options which let me use it across a wide range of temperatures. If you want to get the most comfort out of your Strato Loft 25, I recommend you get a cushy sleeping pad with a high R-value, to go with it. Car camping is supposed to be decadent and that’s an unbeatable combination that will transform the way you sleep in a tent!
