For the minimalist adventurers after maximum warmth on their outdoor escapes, hit the ups and drops with the Sea to Summit Spark 1C Down Sleeping Bag for lightweight and compact comfort!

Featuring a Mummy Fit for thermal efficiency and minimal weight on those wildlife wanders, the Spark 1C boasts a 10D Nylon construction in the shell, lining, hood, and footbox for lightweight breathability and water resistance on every outdoor retreat.

A durable halflength #5 side zipper features a zip plow with two sliders – followed along the top by a downfilled draft tube – while the standard front collar draft helps to trap heat. A technical hood also offers a softtouch adjustment, sitting deep for a warmer wintercamping experience. Plus, to minimise cold spots, vertical and horizontal chest baffles are present in both the lowerhalf and base, while box wall baffles exist at the tophalf of the bag and run through the quilted construction of the lowerhalf.

For fast and light overnighters, keep as comfortable as your pack is compact with the Spark 1C Down Sleeping Bag by Sea to Summit.
