The Mezzo Loft 30 is the most technical bag in our test and represents the best blend of size, weight, and comfort. At 36 inches wide, it offers ample shoulder room, and at just 4 pounds 4 ounces, it’s reasonably light. This is due in part to a lack of padding on the underside; instead, it has a sewn-in sleeve that accepts a sleeping pad, sold separately. Since we tested the bags on a cot, we didn’t use the pad, but it should be considered mandatory for sleeping on the ground. The hood across the top adds warmth and can also work as a pillow. Two Mezzo Lofts can be zipped together to form a double bag.
