Spark Pro Sleeping Bag: 30F Down

Best for ultralight backpacking, the Sea to Summit Spark Pro Sleeping Bag features responsibly sourced, 950+ fill power down for an extremely lightweight and packable sleep system. The 10-denier nylon shell also minimizes our weight while the down itself is treated with a durable water repellent to make it safer to use in humid climates, wet environments, and tents with condensation issues. The Spark Pro adds a foot box zipper and short right-side zipper to add ventilation or let us open up the bag to use as a quilt.
