Sea To Summit Spark Sp1 Regular Sleeping Bag 


The Spark I is the lightest and most compact sleeping bag Sea to Summit make. It's an excellent summer bag whether you're ultra-light through-hiking or cycle touring. It also works well as a booster bag, slipping inside another sleeping bag to add warmth.  Using the warmth of 850+ loft down, the amazing moisture protection of ULTRA-DRY Down™, and a micro-weight 10D Pertex® shell and 15D lining, Sea to Summit have created one of the best warmth for weight minimalist sleeping bags available.
