Glow Synthetic Quilt (50°F)

Synthetic summer quilt that secures to your sleeping bag making a cold-weather sleep system

$149.95 – $169.95

Quilt Temperature Ratings Explained

Unlike sleeping bags, which can be tested using a European Norm (EN) or ISO test protocol, there is no standard for temperature testing of quilts.

All quilt temperature ‘ratings’ are therefore estimates.

Sea to Summit calculates temperature recommendations for quilts based on the weight of down or synthetic-fill used, compared to a similar Sea to Summit sleeping bags. This information is presented using the following icon:

Quilt Temperature Rating

The Lowest Comfort Temperature is the lowest temperature at which we believe an average sleeper will still sleep comfortably. The Functional Limit is the lowest temperature at which a quilt could be used – it is below the threshold of what most users would regard as comfortable.

These recommendations assume a sleeping mat with a tested R-Value appropriate for expected ground temperatures – without this, the quilt itself is unlikely to keep the sleeper warm enough.

A variety of factors impact the warmth of a sleeper - the above temperatures are merely guidelines, not guarantees. It’s important to think of a quilt, an appropriately insulating sleeping pad and a liner as a sleep system. For example - if you plan on sleeping in nighttime air temperatures of 37ºF / 3°C, you should use a quilt with a Lowest Comfort Temperature of 40°F / 4°C, plus a sleeping mat with an R-Value of 2 to 3 (or higher), and consider a Reactor thermal liner.

Description

The Glow quilt is a really lightweight summer quilt insulated with continuous-filament synthetic insulation – ideal for conditions where you might encounter moisture. A drawcord pulls the foot end together into a foot box for cooler nights, and three adjustable straps keep the quilt secured to your sleeping mat.

Quilts are not for everyone, but many weight-conscious backpackers choose a quilt over a sleeping bag for warmer-weather use. The lack of a zipper and hood reduces weight and packed volume, and the broad cut provides real freedom of movement. Sea to Summit quilts have an additional advantage: the QuiltLock system means that the Glow can be connected to a Sea to Summit sleeping bag adding a whole extra season’s warmth to your sleep system.

QuiltLock System

The QuiltLock™ system uses the snap locks located at the shoulder and foot end of Sea to Summit sleeping bags plus the quilt footbox / quilt straps to secure a quilt to the sleeping bag.

This adds thermal performance and versatility to your sleep system: your integrated quilt now works for ultralight summer adventures and turns your three-season bag into a four-season sleep system.
