Product Tested: Sea to Summit Reactor Liner
Web site: http://www.ems.com/products/product_...50582646#specs
Price paid: $50.00, Eastern Mountain Sports (price may vary)
Similar products tried: none
How long/where tested: one overnight in southern Adirondacks, zero degrees or below.
Dimensions: 35 x 82 inches
Weight: 8.1 oz.
Rating: 4
Summary: This was my first use of a sleeping bag liner. My sleeping bag was rated zero, but may have lost some of it's warming capacity over the years. The liner product material, made of Dupont's Thermolite, is a black mesh "sack" with a drawstring. Advertisement says product is "washable and quick drying" (not tested). Also claims to keep sleeping bag clean, and to be odor resistant. In summer, manufacturer claims the liner can be used as a "very light warm weather bag." It appeared that this last claim would hold true only on the warmest of nights (not tested).
Pros: very light and compact (my stuffed sleeping bag included the liner inside with no problem; no need for the liner manufacturer's separate stuff sack). Definite temperature rating improvement, though 15 degree improvement seemed optimistic.
Cons: difficult to get in and out of, in the middle of the night. In spite of stated dimensions, it appeared difficult to cover the entire body without maximum stretching/cinching (awkward). Liner must be cinched tightly to avoid loosing it in the bag during the night (probably varies according to sleeping habits).
Rating: 3.5
N.B. This is my first use of a liner. Rating is extremely subjective, and based on one night's use.
