Outdoor Vitals Summit Mummy Sleeping Bag Product Review

Made from RDS sourced down, these sleeping bags from Outdoor Vitals are designed to keep you as warm as possible, with each one tested to be within 5 degrees Fahrenheit of its temperature rating. We’ll focus on the 0 degree one as we are looking at the best sleeping bag for survival, but it is also available as a 20- and 30-degree bag.

Weighing an ultra-lightweight 2.15lbs, the 0-degree sleeping bag doesn’t lack in quality despite its compact size. It features 800 fill power down, giving it a high warmth-to-weight ratio, along with compressible insulation. It is easy to pack up and take anywhere, and can fit comfortably in a survival backpack if stored correctly.

Its outer shell is built from tough nylon ripstop material, so it is designed to withstand harsh conditions. This design is ideal for any survival environment, while remaining lightweight with only a 20-denier thickness.

It’s also a roomy sleeping bag, despite being mummy-style, as it is made to be large enough not to press against the sides and reduce any loft.

One notable issue that some customers have highlighted is the zipper quality. It may be prone to getting stuck, which could be a serious issue when you need to preserve heat.
