Spark SpIII Sleeping Bag: 18F Down by Sea To Summit
The ultralight Sea to Summit Spark SpIII Sleeping Bag compresses to the size of your palm for backpackers, climbers, and cyclists. Primarily focusing on giving you the lightest bag out there, Sea to Summit stuffed the Spark with 850-fill down for the best possible warmth-to-weight ratio. This bag's nylon shell is windproof and prevents the down from breaking through, and the smooth nylon lining adds some durability. Going beyond an ultralight design, Sea to Summit added its Ultra-Dry Down treatment to help this bag resist moisture and enhance your comfort regardless of the conditions. The Spark SpIII has a contoured mummy shape to closely fit your body while you sleep. Its full hood wraps around your head to eliminate the possibility of waking up with freezing ears, and the 1/3-length zipper on the left helps maximize warmth. The Spark compresses so small that Sea to Summit had to re-engineer a new compression sack for it. So when you get this bag, you might be able to stuff your pack with a few extras even if you are a minimalist.

The pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
