Initial Thoughts on the Sea to Summit Spark Down Sleeping Bag
A premium bag for those in need of a lightweight and packable sleeping bag. I loved the warmth this bag provided (850+ premium down!) while it still took up minimal space in my pack. Best suited as a 3-season bag providing versatility whether you are adventuring to the mountain, trails or doing some car camping.
While you might be thinking a 15-degree bag might be too warm for some during the summer months don’t worry, it also comes in 30 and 45 degrees as well. One of my favorite features of this bag is the unique zippered foot vent which allows for some temperature regulation on those warmer nights in the backcountry.
