Sleeping Bag Temperature Ratings Explained

The EN Rating scale is a scientific test to determine the warmth of a sleeping bag. The test produces a Lower rating (for male sleepers) and a Comfort rating (for female sleepers). Both are listed in the features table on the product page.

A unisex sleeping bag with a Lower limit of 14ºF means a man should be comfortable down to air temperatures of 14ºF. The same bag will also have a Comfort limit, in the realm of 27°F, so a woman would be comfortable down to an air temperature of 27ºF. These ratings require a sleeping mat with an R-Value appropriate for expected ground temperatures – without this, the sleeping bag itself is unlikely to keep the sleeper warm enough.

A variety of factors impact sleeping bag warmth - the above temperatures are merely guidelines, not guarantees. It’s important to think of a sleeping bag, an appropriately insulating sleeping pad and a liner as a sleep system. For example - if you plan on sleeping in nighttime air temperatures of 27ºF / -3°C, choose a bag with a gender-appropriate rating of 23°F / -5°C, plus a sleeping mat with an R-Value of 2.5 to 3, and consider a Reactor thermal liner.

Description

The eVac™ Dry Sack utilizes 70D lightweight nylon fabric for strength and eVent® waterproof fabric on the base to allow eVac-uation of air for compression. It's an excellent option for storing and compressing clothes and sleeping bags without the use of straps. Just pack the items in, roll the sack down and push the air out to save valuable packing space within your backpack. They're an oval shape, making them perfect for sliding into the contours of your pack and all seams are double stitched and tape-sealed.

Technical Features

70D Waterproof Fabric - High Performance

Super tough, super pliable, high thread-count 70 Denier fabrics. The PU coating is highly waterproof (rated to 10,000mm hydrostatic head), and is colored bright white to make it easy to find your gear inside these bags.

eVent™ Fabric

eVent™ fabric is an air-permeable, waterproof laminate used in two different functional areas in Sea to Summit products:

In the base of our best-selling eVent Compression Dry Sacks, Evac Dry Sacks and Ultra-Sil™ Compression Dry Sacks. In this application, the laminate utilizes a 40 denier nylon face fabric: the material allows air to be pushed out of the dry sack/compression dry sack but prevents water from entering. This means you can compress the air out of a dry sack without needing a purge valve!.

In the upper section of our Quagmire and Alpine Gaiters. In this application, the laminate utilizes a 70 denier nylon face fabric. The material allows perspiration to pass through easily but prevents external water from entering. The result: waterproof protection and superior breathability!
