ZANE ARTS KUMO Goose Down Sleeping Bag

ZANE ARTS KUMO Goose Down Sleeping Bag

850FP high-quality goose down for lightweight warmth. Filled with high-spec 850-fill-power goose down, this sleeping bag provides excellent thermal insulation and comfort. Specifically designed for alpine environments, it balances lightweight performance with high cost-efficiency, making it ideal for mountaineering and camping enthusiasts who value gear efficiency.

Features

Spacious and Comfortable Cut

An overly tight fit not only makes for an uncomfortable night's sleep but can also deform the down chambers and compress the down, compromising thermal performance. Therefore, we intentionally avoided extreme, slim-fit designs in favor of a moderately loose and comfortable cut, ensuring the down can fully loft to provide optimal insulation.

850FP High-Quality Goose Down

Filled with rigorously washed 850-fill-power goose down to ensure superior warmth and comfort. White and gray goose down share identical performance characteristics; however, since white down is more expensive, we have selected high-value gray goose down for this product, allowing you to enjoy the same excellent thermal efficiency at a more reasonable price point.

Effectively Locks in Warm Air

For models with 450g or more of down fill, we have integrated a thick down-filled collar around the neck to prevent warm air from escaping, featuring a gap-free design to maintain interior warmth. (Left: 450g model / Right: 350g model)

Diagonal Upper Zipper Design

Placing the zipper at the bottom of the sleeping bag can often allow cold air from the ground to seep in, affecting thermal performance. This bag features a diagonal upper zipper design, which not only reduces cold air infiltration but also makes it easier to open and close, enhancing overall comfort during use.

Down Chamber Construction

Sleeping bag structures are generally divided into "sewn-through" and "box construction" types. To enhance thermal efficiency, models with 450g or more of fill utilize a 3D box construction, which effectively minimizes heat loss at the seams and further elevates overall insulation performance.

Compatible with Down Booties (Camp Shoes)

In extremely cold conditions, layering clothing is the most efficient way to stay warm. This sleeping bag is designed with a slightly roomier fit, allowing you to sleep comfortably even while wearing down pants or down booties, ensuring ease of movement and comfort.

Anti-Snag Zipper Design

Equipped with high-performance YKK zippers and a proven anti-snag strip design, the likelihood of fabric getting caught in the zipper is significantly reduced, improving smoothness and durability when entering or exiting the bag.

Non-Detachable Zipper Slider

Most sleeping bags feature a bottom slider that can fully detach, which often leads to the slider falling off during operation, causing unnecessary inconvenience. This product uses a non-detachable slider design that stays in place, eliminating the hassle of re-threading and ensuring smoother, more reliable use.

Non-Locking Zipper

While traditional locking zippers prevent accidental openings, they can hinder the fluidity of the zip. We have prioritized smooth operation in this product by selecting a non-locking zipper, allowing for effortless and intuitive opening and closing when getting in or out of the bag.

Lightweight × Efficient Storage

Using 850-fill-power high-quality goose down delivers outstanding insulation while maintaining lightweight, highly compressible properties for easy portability. This is a high-performance sleeping bag that perfectly blends the lightweight, warmth, and mobility required for alpine activities.

Includes Waterproof Storage Bag

Down loses its insulation power when damp. To mitigate this, our sleeping bag comes standard with a waterproof roll-top storage bag, effectively protecting the bag from moisture and providing peace of mind in outdoor conditions.

Includes Large Breathable Storage Mesh Bag

Storing a sleeping bag compressed in a waterproof bag for extended periods can cause the down to deform and lose its loft, affecting thermal performance. To extend the life of your bag and maintain its condition, we provide a large, breathable mesh bag for loose storage at home or during non-use periods, helping to preserve the loft of the down.
