Therm-a-rest Antares HD 15

EN comfort rating: 27 degrees F. Fill: 750 drydown. 34.4oz ($500, cascadedesigns.com)

The 2 pound, 2 ounce Therm-a-Rest Antares HD is the smallest-packing bag in our test. Filled with 750 power drydown the Antares is EN rated at 27 degrees for comfort. It’s similar to the Lost Ranger in that the Antares HD has less insulation on the bottom and relies on the pad for warmth. Instead of a full sleeve, the Anteres HD uses two elastic “SynergyLink™ Connectors” to keep the pad in place. Unfortunately the matching Neo Air pad‘s material is slippery, especially when combined with the Antares HD. It’s nearly impossible to stay on the pad, and the “SynergyLink” connectors are too stretchy. In testing we liked this bag a lot more used on other sleeping pads, which made slipping off less of an issue.

It’s fully durable water repellent coated which is great for sleeping under the stars. There is a nice external gadget pocket, but it’s across from the main zipper and hard to find in the dark. We’d gladly trade it for a zipper latch as the zipper is prone opening up during the night. Despite the EN rating of 27 for comfort, we found the bag cool even in the mid 30’s due sliding off the pad and the caveats below. In the end, the Antares is high on the tech factor but low on sleepability.

Caveats: A large part of the warmth comes from heat-reflecting lining, which has a crunchy sound and poor tactile feel. The cord used for the draft collar and mummy hood is too thin; the friction stop does not work and the hood and collar open with any movement.

Best for: Immobile sleepers who need the smallest-packing bag that can handle damp conditions.
