Why We Like The Spark SpII 28 Down Sleeping Bag
Experience ultimate comfort and convenience with the Spark SpII 28 Down Sleeping Bag by Sea to Summit. Perfect for backpackers, racers, cyclists, and alpine climbers, this ultralight and compact sleeping bag offers a minimalist design without compromising on a good night's sleep outdoors.
Featuring 850-fill down, this sleeping bag provides exceptional warmth-to-weight ratio, making it one of the lightest options available. The durable nylon shell is not only windproof but also prevents the down from breaking through, ensuring long-lasting performance. Meanwhile, the smooth nylon lining adds an extra layer of durability.
What sets this sleeping bag apart is the Ultra-Dry Down treatment, which enhances its resistance to moisture. So, regardless of the conditions, you can rely on this bag to keep you warm and comfortable throughout the night.
