Sea to Summit Talus TsI 34ºF Ultra-Dry Down Sleeping Bag


Sea to Summit Talus TsI 34ºF Ultra-Dry Down Sleeping Bag

The Talus boasts many of the features seen in higher priced bags and is ideal for a wide range of activities – offering comfort, warmth, and moisture shedding capability.

Talus's hood is designed to cocoon your head completely in a way that maximizes the available loft without making it feel claustrophobic. There is an adjustable collar to help fine-tune the warmth and seal out drafts. A drawcord channel in the collar and hood are buried deep within the down so there are no annoying harsh edges to push into your neck or face. The discreet zippered pocket is perfect for your MP3 player or valuables, and the main zipper, which can be joined to other Sea to Summit® bags, has an anti-snag system that really works!

The cut of the bag and baffles are engineered to prevent down shift and allow the down to reach its maximum loft  - simple in theory but complex to execute. It involves using differentially cut, three dimensional side-walls and curved baffles. The relaxed mummy shape is designed to maximize thermal efficiency and minimize overall weight. It is cut with a larger hood, broader shoulder and chest area than many mummy bags: room to move comfortably without compressing the down and causing cold spots.

The Talus features an improved 2D NanoShell™ outer shell fabric, specially engineered for breathability (Moisture Vapor Transmission Rate: 7500 g/m2/24hr) and excellent water repellency (1000mm). This helps ensure that external moisture, such as condensation on the inner wall of a tent, doesn’t dampen your bag or your enthusiasm for venturing into the backcountry.

The lightweight Talus TsI, a great three-season bag for those wanting a more traditional bag that is light and compact. Doing a road trip with some overnight walks thrown in as well? Taking off on an extended overseas backpacking sojourn? This bag will give you peace of mind without weighing you down unnecessarily.

Following a successful 1984 climb up the north face of Mount Everest, one of the summiteers, Tim Macartney-Snape decided to return six years later so that he could do what no one else had done - climb it starting from sea level, that is from "sea to summit".

For this trip, in 1990, Tim swam in India's Bay of Bengal and then set off on foot across the Gangetic plain toward the distant Himalayan foothills and four months later, set foot once again on the highest point on earth. Tim's solo ascent of Mt. Everest was named the "Sea to Summit" expedition.

Back in Australia, he joined forces with friend Roland Tyson to build a business that could make use of their knowledge of the outdoors to create truly ingenious, well-made but affordable outdoor equipment. They named their company Sea to Summit® after Tim's expedition and the business prospered. Today the Sea to Summit brand continues to provide innovative gear and serves a growing band of outdoor enthusiasts all over the world.
