About This Item

Temp Rating

35 Degrees or Higher

Insulation Type

Down

If you're counting grams, but still count on a great night's sleep, the Spark may be the right bag for you. Filled with RDS-certified 850+ fillpower goose down treated with a non-PFC Ultra-Dry Down treatment, the Spark is constructed with a technical hood and zipper draft tube to retain warmth. Comfort comes from a super-breathable 10 denier liner fabric, while a 10D shell with a non-PFC DWR plus a highly water repellent hood and footbox fabric shed wind and condensation. The full-length zipper model can be zipped to an equivalent Women's Spark for comfort that couples can share.

DESIGN & DETAILS:

  • RDS-certified, 850+ fillpower goose down with a non-PFC Ultra-Dry Down treatment for maximum thermal performance
  • Ultralight, breathable 10D nylon liner and a 10D shell with PFC-free DWR keeps the hood and footbox highly water resistant
  • YKK #5 zippers with zipper plow provide reliable, snag-free operation
  • Technical hood, anatomical footbox and an ergonomic mummy shape - ultralight doesn't have to mean ultratight
  • Sewn through for lighter weight (7°C|45°F), Hybrid box baffles in torso/sewn through in leg area (-1°C|30°F) or full box baffles for maximum warmth (-9°C|15°F)

TECHNOLOGY:

  • Ultra-Dry Down™ uses a non-PFC hydrophobic treatment to ensure it absorbs less moisture and dries more quickly
  • QuiltLock™ system uses the snap locks located at the shoulder and foot plus the quilt footbox / quilt straps to secure a quilt to the sleeping bag
  • Brand : Sea to Summit
  • Country of Origin : Imported

Took The Spark Down To

[This review was collected as part of a promotion.] Took the Spark Down to the woods on a Canada trip- loved the light weight, compaction of the bag. Stayed warm throughout the night. Had some rain get in the tent, the bag dried out extremely quick. The bag is soft and comfortable, really like how it's not overly heavy and still retains it's loft. I need equipment that is light, durable, and quality. I don't want to be out in wild, miles from anything and be wet, cold, and miserable with bad gear. Very happy with the product!

Perfect Summer Bag

[This review was collected as part of a promotion.] Had this bag with me on an 8-day bikepacking trip round the Pacific Northwest. Light, packs small, and functions as you’d expect (no zipper snags)!

Overall Great Warmth/weight Ratio

[This review was collected as part of a promotion.] Over three months I've taken this bag camping on the Alaska Marine Highway (ferry) and a couple 1-3 nighters in the Cascades. It's not the warmest bag you'll find, and on a cold night in the mountains (in a 3-season tent), I was a little bit cold -- though not uncomfortably so. However, it's a great compromise on warmth/weight -- and especially warmth/volume. It packs up so small, best part. The half zip is a little annoying, but I understand the compromise.

Spark Bag

[This review was collected as part of a promotion.] Do not like 3/4 zipper. Makes bag difficult to get in out. Do appreciate the lightness of the bag.
