I'm Abigail Scott, an author, adventurer, and mother of three. When I'm not navigating the beautiful chaos of motherhood, you can find me tackling the turbulent waters as a professional whitewater kayaker or scaling impressive rock faces as a climbing guide. The rush of adrenaline, whether from kayaking or climbing, is a feeling I cherish deeply. But the thrill doesn't stop there; I capture the breathtaking allure of nature through my lens as a professional photographer. And when I'm not submerged in the wild, my software engineering skills amplify my outdoor pursuits, allowing me to harness technology in unique ways. Through my writings, whether articles or blog posts, I share not just my adventures but my heart, hoping to spark a flame of inspiration in others to break boundaries and experience the world's wonders.

Description

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.
