Katabatic Gear Alsek Quilt

The patented system uses elastic cords and clips to secure the quilt to your sleeping pad, creating a seal that prevents cold air from sneaking in when you move. It essentially wraps the quilt around you like a cocoon, mimicking the thermal efficiency of a mummy bag without the restrictive hood.

Yes, thanks to the continuous baffles, you can manually push the down from the bottom of the quilt to the top or sides. This allows you to customize the warmth distribution based on the ambient temperature or your personal sleeping preferences.

The 22°F rating is accurate for most users, provided you use a sleeping pad with an appropriate R-value to insulate you from the ground. Because quilts lack a hood, wearing a warm beanie or a down hood is recommended if you are sleeping near the lower limit of the temperature range.

The trapezoidal shape is designed to follow the natural contour of your feet when you are lying on your back or side. It prevents your feet from compressing the down against the shell, which maintains loft and keeps your toes warm throughout the night.

The ExpeDRY treated down is highly effective at resisting moisture absorption, which helps the quilt maintain its loft and thermal performance in humid or damp conditions. While it is not waterproof, it provides a crucial layer of protection against condensation inside your tent.

The Alsek is designed to accommodate users up to 78 inches tall. If you are near this height limit, you may want to consider your sleeping position, as side sleepers often have more flexibility than those who sleep strictly on their backs.
