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:
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
Insulated with RDS-certified, 850+ fillpower goose down with a non-PFAS Ultra-Dry Down treatment, the Ember quilt was designed for multi-season use with an excellent warmth to weight ratio. In warmer conditions, the ability to easily ventilate keeps you comfortable. As temperatures drop, the drawcord footbox helps you retain warmth and the light, breathable 10D nylon shell fabric is treated with a non-PFAS DWR finish to repel moisture, while the 10D nylon liner fabric is there to deliver pure comfort. The Ember is easy to secure to your sleeping mat with the attached straps or add it to your Sea to Summit sleeping bag using the integrated QuiltLock system for a thermal boost in colder weather.
Technical Features
850+ Fill Power indicates that one ounce (30g) of down will re-expand to over 850 cubic inches after compression.
The higher the Fill Power, the more the down will insulate for a given weight. This means that less down can be used to achieve the same temperature rating – important for compressible performance sleeping bags.
Every Sea to Summit down sleeping bag comes with a test report from the International Down and Feather Laboratory IDFL confirming the down loft and quality. All our down is RDS certified responsibly sourced, and hydrophobically treated with a non-PFAS Ultra-Dry Down finish
100% of the down used in our sleeping bags and quilts is independently certified to the Responsible Down Standard (RDS). The RDS certifies down against animal welfare requirements and tracks it from the source to the final product. The purchase of RDS certified products demonstrates demand for better animal welfare practices in the down and feather supply chain. Sea to Summit is certified to the RDS.

Sea to Summit sleeping bag fabrics and insulation are made without PFAS compounds. The non-PFAS DWR finish on the shell helps prevent the insulation from becoming damp if the bag comes into contact with mositure, such as tent wall condensation.
Ultra-Dry Down is a non-PFAS hydrophobic treatment that absorbs less moisture and dries more quickly. It does not affect the 'breathability' or the lifespan of the down and lasts through at least 20 washings. The down used in our sleeping bags is responsibly sourced.
Sea to Summit Dry Bags, Stuff Sacks and Compression Bags use a non-PFAS Durable Water Repellent finish to help shed water. Big River bags use a non-PFAS PU coating.
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.

Frequently Asked questions
Is the temperature rating EN or ISO tested?
No. There is no EN/ISO temperature test for quilts. The 'rating' is an estimate based on sleeping bags with similar materials/down fill weights
Is the Ember suitable for cold-weather use?
The Ember 2 is our warmest quilt. With the footbox drawcord cinched tightly, a sleeping mat with an R-Value of 3+ (and ideally a Reactor liner) you can get close to the freezing point. Quilts do not have hoods, so make sure to wear an insulating hat
Can the Ember be coupled to another quilt?
Yes - the press studs on the side (usually used for sleeping mat attachment straps) can couple two Embers together
