Product description Sea To Summit Spark SP IV Sleeping Bag
Ultra-light and technical, our Spark™ Series bags are designed to keep you as warm as possible while minimising packed weight and size.
- The Spark™ Series spans everything from an ultralight liner to an expedition weight mid-winter bag. While the end usage is very different, they reflect a design ethos of matching weather conditions to the lightest bag possible.
- The secret to the impressive performance is a combination of premium materials and careful design. The RDS 850+ Loft premium goose down, light-gauge #3 YKK zip and high performance 10D Nylon shell and 7D lining fabrics, set the stage for superior performance. These materials are combined with a contoured mummy design for efficient insulation, and that mummy design is then tweaked for each model to best fit the use scenario.
- Our ULTRA-DRY Down™ water-repellent treatment protects the down from external moisture and condensation from the inside of the bag, virtually eliminating the negative effects moisture has on down. All Sea to Summit Down Sleeping Bags use Responsible Down Standard (RDS) certified down. The ULTRADRY Down™ protection also makes the Spark™ an impressive hard-alpine or adventure racing bag, where every gram is counted and down has never been a viable option.
Features:
- Ultralight 7D and 10D fabrics for minimal weight and packed size
- RDS 850+ Loft Premium Goose ULTRA-DRY Down™ for maximum insulation value
- Contoured mummy shape for comfort and efficient insulation
- Vertical chest baffles prevent down migration and cold spots
- Vertical box baffles in the torso area accommodates extra down and boosts warmth around the core, vertical baffles on chest optimises positions of down to prevent it moving during use
- Lower part of the bag uses a sewn through horizontal baffle construction to minimise weight ½ zip with two sliders aids access and allows ventilation from mid-section of bag
- Draft tube prevents heat loss through the zipper
- Includes hood draft collar
- Includes lightweight Ultra-Sil™ Nano compression bag for compact storage
Specifications:
- Overall weight: 880 G
- Stuffing weight: 620 g
- Shell: 100% Nylon, Lining: 100% Nylon, Primary Filling Material: GOOSE DOWN (Min. 90% Down), Stuffsack: 100% Nylon excluding Trims

There was a delay in delivery but due to delivery from Brazil, I was charged. The sleeping bag is comfortable, the regular size is even bigger than I imagined (I'm 1.60 m). Product arrived well packaged with all brand authenticity. Pay attention to comfort temperature -8 degrees (fem). I haven't taken it to the mountain yet but I'm sure I'll be comfortable and the weight in my backpack will be much lighter.

I am a motorcyclist and sometimes I lacked 2-3 degrees in my old sleeping bag. Chose a lot of options. Seatosummit Spark4 is what I need. Compact, lightweight, warm, and most importantly inexpensive for decent quality. I recommend!
Just what light walkers need!

The Regular model is a perfect fit for an 184cm tall Large clothing size man. The bag actually weighs less than 900g and packs into a really small one just as advertised. Also included were comprehensive instructions on how to maintain the bag. I really appreciate this because the general instructions may not be the best, especially for such a technical bag! Will definitely keep me warm from late autumn in Lapland :)

Info temperatures sea to summit spark IV

Kind staff Trekkin, I'd like buy in your shop a Spark IV spleeping bag regular. I sew on your web site limit temperatures confort = -5 °C /-10°C, but on official web site sea to summit said -15°C. What's the real temperature limit confort in this sleepingbag? Best regards. Ivano
Answer of Daniel
The spark spIV comfort temp is -8ºC, limit -15ºC and extreme -36ºC. I think it is a low rating though! I’ve used it as a quilt down to -20ºC and been very comfortable.
