Incredibly lightweight and compressible, the Sea to Summit Spark SP III is made for ounce-counting backpackers and thru-hikers. It weighs just a pound-and-a-half, features weather-resistant treated down insulation, and has a temperature rating of 25 Degrees F.

Renowned for their efficiency in retaining heat and compressible properties, the feathers and fibers of down have an incredibly soft, comfortable feel and, despite advances in synthetic materials, continue to provide the best warmth-to-weight ratio of any insulation available. The one inherent weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet, but the bag’s premium 850+ fill Ultra-Dry Down performs differently. Ensuring consistent thermal performance, a hydrophobic treatment enables the insulation to stay dry longer and dry faster if it should become wet than traditional down insulation. Ultra-lightweight 10D nylon exterior shell fabric has a DWR treatment to further protect the interior from moisture. A 15D nylon interior has a soft-touch fabrication that provides next-to-skin comfort.

The bag uses baffled construction to keep the insulation from migrating and creating cold spots. A fully insulated, adjustable hood bolsters warmth and a 1/3-length zipper balances weight, provides access to the interior of the bag, and maximizes thermal efficiency. A tapered footbox also helps to save weight while increasing overall warmth.

The Sea to Summit Spark SP III sleeping bag is available in your choice of Regular (fits to 6’ 0”) and Large (fits to 6’ 5”) size options. An Ultra-Sil compression stuff sack and a size-adjustable storage cube are included with each bag.
