Ember™ Down Quilt (40°F, 30°F & 20°F)

THINK OUTSIDE THE BAG

$269.00 – $419.00

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 23ºF means a man should be comfortable down to air temperatures of 23ºF. The same bag will also have a Comfort limit, in the realm of 32°F, so a woman would be comfortable down to an air temperature of 32ºF. 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

An Ember quilt can be an ideal option for bikepackers, ultralight hikers and travelers.

A well-constructed quilt means freedom: Freedom from the weight of a sleeping bag zipper; freedom from the constrictive shape that comes with some sleeping bags.

The Ember™ Series takes the simplicity of the quilt concept a step further. The high quality 850+ loft Ultra-Dry Down and 10 D outer / 7D inner shell material mean incredibly lightweight and tiny packed size. The snap-on attachment straps keep your quilt located on your sleeping mat, while the drawcord base of the 40°F and 30°F give the Ember a ‘shape-shifter’ function: wider at the base for more freedom of movement when it’s warm, snugged down when it’s cooler.

Is the Ember Quilt…?

  • Suitable for cold-weather use? The warmest Ember 20°F has a sewn-in foot box, and is designed for temperatures a little under freezing (with an appropriate sleeping mat). Quilts do not have hoods – you will need a warm hat on chilly nights.

  • Rated using the EN temperature test protocol? No. The EN test does not apply to quilts; so not quilt on the market will have an EN rating. We refer instead to a ‘lowest comfortable temperature based on comparable Sea to Summit sleeping bags.

  • Able to be coupled with another Ember Quilt? Yes. The press-studs along the edge of the quilt (usually used for the sleeping mat attachment straps) can be used to join two Embers together.

Technical Features

850+ Loft Ultra-Dry Down™

The highest-lofting down used in any of Sea to Summit’s sleeping bags. 850+ Fill Power indicates that one ounce (30g) of down will re-expand to over 850 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.

 

All of which means you can rest easy.

Responsible Down Standard (RDS)

All Sea to Summit sleeping bags use only down which is certified according to the Responsible Down Standard. The RDS is helping shift the entire down and feather industry towards more humane animal rearing and handling practices. Overseen by the industry leading Textile Exchange, the RDS requires independent, third-party assessments of all aspects of animal rearing and handling throughout the entire supply chain. By using only down that meets the audited requirements of the RDS, we can have confidence that each phase of the collection process has been completed with the welfare and ethical treatment of waterfowl in mind.

UL 10 Denier Nylon

Despite being incredibly lightweight, the 10 Denier UL Nylon is down-proof and surprisingly durable. A DWR finish helps to shed external moisture. This fabric is part of the secret to making the Spark and Flame Down Sleeping Bag Series some of the lightest, most packable sleeping bags available today.
