Size Guide

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.



The Alpine™ eVent® Gaiters are perfect for mountainous, high altitude pursuits. They're trimmed down for speed and lightweight appeal and have an impressive fit and feature list, without the bulk. The upper section is constructed using an eVent laminate for ultimate breathability when you’re moving fast and light.

Gaiters aren’t just for winter sports. Use them in wet conditions to keep the mud out of your boots, or to prevent ticks from getting into your socks. Gaiters will also protect your lower legs from sharp vegetation if you are walking off-trail.

Is the Alpine eVent Gaiter...

  • Breathable? Yes! The eVent laminate allows moisture vapor to pass through while preventing external water from getting into the gaiter. Perfect for aerobic pursuits such as ski touring.

  • Really Rugged? Rugged enough for most backcountry sports. If you need an ever tougher gaiter, look at the Quagmire eVent Gaiter.

  • Fitted with a replaceable foot strap? Yes. The gaiter is secured underfoot using a Hypalon strap – if it should ever wear through, it can easily be replaced with the Gaiter Strap, which is almost indestructible. Read the blog How to Replace the Straps on Your Alpine or Quagmire Gaiter

Technical Features

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!
