What shoppers need to know

- Style: Mother
- temperature rating: 49 degrees Fahrenheit
- to fill: Spirafil
- Best use case: Camping and backpacking trips from summer to early fall
Lots of sleeping bags from the big brands are designed to keep you warm in some harsh conditions, but this is of little use to summer campers, who are probably going to be fine apart from a few sweltering nights here and there.
This sleep bag was designed for those who get cold easily, keeping them comfortable up to about 49 degrees, and for those who feel hot at night, up to 56 degrees. The sleeping bag is made with Marmot’s premium Spirafoil insulation, making it soft enough to keep on top of, and has a long zipper on the left side to trap some extra warmth in high temperatures.
Note that this is also a lightweight sleeping bag, so it’s easy to pack and take with you, making it a must-have for backpacking.

what shoppers are saying
One user, who said the bag has accompanied them on several backpacking trips, said, “Sure it’s not the warmest bag, but it’s perfect for the hot summer months.” And it’s exactly the kind of review you’d expect from someone who has probably tried this bag beyond the ideal year, but can still see its value in summer.
Another said it more simply. “It’s all you need in a warm-weather sleeping bag: light, compact and warm.”
Marmot Nanowave 45 Sleeping Bag It’s on sale right now for $75 as part of the REI 4th of July Deals event, running through July 6.
