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 3°C, you should use a quilt with a Lowest Comfort Temperature of 4°C, plus a sleeping mat with an R-Value of 2 to 3 (or higher), and consider a Reactor thermal liner.

TECHNICAL FEATURES

The second highest-lofting down used in any of Sea to Summit’s sleeping bags. 750+ Fill Power indicates that one ounce (30g) of down will re-expand to over 750 cubic inches after compression. Higher loft means that less down can be used to achieve the same temperature rating – important for performance sleeping bags. The loft and down quality/composition are independently tested by the International Down and Feather Laboratory (IDFL) – a copy of the certification is supplied with every Sea to Summit sleeping bag. The down is responsibly sourced and RDS certified and treated with the environmentally-friendly Ultra-Dry Down treatment.

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.

Ultra-Dry Down is a non-PFC treatment hydrophobic treatment applied to the down during down processing. It is not a coating (which would reduce the ability of the down to loft), it comprises of very small particles of a polymer that cause the down clusters / feathers to repel water. Ultra-Dry Down is PFC and PFAS-free. Hydrophobic down is not waterproof; but it absorbs less water than untreated down and dries much more quickly.
Ultra-Dry Down does not affect the loft or lifespan of the down, or its breathability. The treatment will last through at least 20 washings.

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
What is the difference between the Tanami Tm I and Tm II?
The Tanami Tm I has 350g of down in sewn-through chambers. The Tm II has 700g of down in fully-baffled chambers.
Will the foot-end drawcord system fit over the Comfort Deluxe SI Double Mat?
Yes. The Tanami can be snugged down to prevent drafts or the quilt shifting.
Is the temperature rating EN or ISO tested?
No. There is no EN/ISO test for quilts (we quote a lowest comfort temperature of 50°F based on similar sleeping bags).
