ENGINEERED FOR ULTRALIGHT WOMEN BACKPACKERS

$99.95 – $109.95

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 Women’s Delta Core-V™ concept is simple: remove enough foam to cut down weight, leave enough foam to ensure comfort and warmth. The Women’s UltraLight Self-Inflating Sleeping Mat is constructed with Comfort Warmth Zones in the hip foot and torso areas to provide extra support and insulation for the woman backpacker who wants to keep her load light.

Silicone prints on the upper surface prevent your sleeping bag slipping, and the flip-over multi-function valve makes rolling up the self-inflating mat really easy.

Our blog post "Which Mat to Choose" has some helpful tips on picking the perfect air sleeping mat (or reasons why you might prefer a Self-Inflating sleeping mat)

Technical Features

SI Multi-Function Valve

We have literally put a new twist on our very successful multi-function valve so it specifically addresses the inherent characteristic of self-inflating mats - that is, the problem of the foam trying to re-inflate as you're packing up. We've engineered the "one-way" inflation valve to be reversed and used to prevent the mat from drawing air back in. This allows you to roll the mat up as small as possible without fighting re-inflation as you go. This patent-pending valve design has the same slim profile, faster inflation than traditional screw valves, easy pressure fine tuning, and super fast deflation rate as our air mattresses and pillows.

Pillow Lock™ System

The Pillow Lock™ System comprises of self-adhesive hook-and-loop patches which are supplied with all Sea to Summit sleeping mats (as of Spring 2019),

Attached to your sleeping mat, these patches secure your pillow and prevent it slipping – yet they will not snag on clothing or other lightweight fabrics.

All Sea to Summit Pillows (as of Spring 2019) are compatible with this system. Existing pillows can be made Pillow Lock™ compatible by adding an Aeros Pillow Case.

Women's Delta Core-V­™

The Women’s Delta Core-V™ system uses a revised pattern of Delta-shaped vertical cores to leave foam intact in the hip, foot and torso areas to create extra-comfort / extra warmth zones.

The coring technology results in a smaller packed size and lighter weight than conventional self-inflating mats while providing extra support and insulation where women need it most.

The Women’s Delta Core-V™ technique is used in our Women’s UltraLight SI models.
