Technical Features
850+ LOFT ULTRA-DRY DOWN
850+ LOFT ULTRA-DRY DOWN
The second highest-lofting down used in any of Sea to Summit’s sleeping bags or quilts. 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 our non-PFC Ultra-Dry Down™ treatment.
QUILTLOCK 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.
RESPONSIBLE DOWN STANDARD (RDS)
RESPONSIBLE DOWN STANDARD (RDS)
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. To learn more about RDS visit https://textileexchange.org/standards/responsible-down/
Non-PFC
Non-PFC
Sea to Summit sleeping bags do not contain PFCs.
Ultra-Dry Down™ uses a non-PFC hydrophobic treatment to ensure it absorbs less moisture and dries more quickly. The treatment 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 RDS-certified responsibly sourced.
Down and synthetic-insulated sleeping bags utilize a non-PFC DWR treatment on the shell fabric for external moisture repellency. This helps prevent the insulation from becoming damp if the sleeping bag comes into contact with condensation on a tent wall, for instance.

Frequently Asked questions
Can I open a Spark flat for use as a quilt?
No - the ultralight Spark does not have a footbox zipper. For this feature, see the Spark Pro or Ascent sleeping bags
Can two Sparks be zipped together?
Any of the Spark/Women's Spark models with full-length zippers can be zipped together
How much room is there in a Spark?
The Spark is designed to be ultralight, so the fit is a little more snug than a comfort-sleeping bag like the Ascent. But - it is still cut to provide room to move.
