Sea to Summit Spark Sleeping Bag
Features & how to pack away
Details & Specs
Technical, super compact and ultra-lightweight – the Spark Sp0 is the summer adventure bag that doubles a liner when the weather cools down.
This bag features a contoured mummy shape to maximise insulation and has a 14°C comfort rating and 10°C lower limit making it ideal for summer conditions. The Spark has a 10D nylon shell with a 7D lining and a light-gauge #3 YKK zip to keep the packed size and weight as minimal as possible.
It’s filled with RDS certified 850+ Loft premium goose down which has an ULTRA-DRY down water-repellent treatment to protect it from moisture and ensure performance in technical conditions. This bag has a sewn through quilted construction to keep the down positioned and can be used as a liner to add more warmth to an existing bag.
With an integrated stuff sack included for storing it compactly when you’re out in the field, the Spark Sp0 is the streamlined sleeping solution for fast-paced warm expeditions.

You could probably make it work if you're desperate, but its not a great match up. The Spark Male/Unisex bag is quite a different size and shape to the womens specific Flame series. Given the investment, we'd recommend you go with the Flame Fm0 instead.

Liner for Other Spark Bags1 answer
This is marketed as a sleeping bag liner. Will this fit as a liner inside the other spark range? For example could it be used to boost the rating of an Sp2? Or are the dimensions too tight for it to loft enough inside another minimalist mummy bag like the other spark bags.
Jack - North Perth, WA (1 year ago)
The SP0 can be used as a liner in the SP3 or SP4, as they are 'expedition width' bags to allow for an extra liner or clothes to be warn inside them. The SP2 is the same size as the SP0, so while you can make it fit if you're on the smaller side, it won't allow the bag to fully loft.

Will this quilt lock to a ember III?1 answer
Hi guys - will this quilt lock to the Ember Quilts? Is this the same w the Spark 1 also?
Jared - Wyoming, NSW(1 year ago)
It wont, but compared to other quilt options the Ember has comprehensive mat straps. These are obviously designed to wrap the quilt around a sleeping pad, however, they also allow you to cocoon the quilt around your existing sleeping bag as an alternative.

How much extra warmth would this add to another sleeping bag? Would it be more than a S2S thermolite reactor extreme?1 answer
I’m looking at the most versatile use for this bag or spark 1
Paul - Doreen(3 years ago)
The Spark SP0 has a comfort temperature of 10C, so when used as a liner it should add about the same to another bag. Based on the construction and materials if it has space to loft then it should add more warmth than the Thermolite Reactor Extreme.
