About this product

The Klymit KSB 0F/-18C is a mummy-style sleeping bag engineered for cold-weather camping, rated to 0 F (-18 C) and weighing 2 kg (4.5 lb) in the standard size. Its hybrid insulation system pairs 80/20 grey duck down on top, rated at 650 fill power, with synthetic fill on the bottom, striking a practical balance between warmth, weight, and moisture resistance. The 20D Nylon 400T shell with WRC6 water-resistant coating keeps the fill protected, while Flexible Stretch Baffles hold insulation close to the body and accommodate movement throughout the night. Length Locks allow users to customize the fit around the feet, and a built-out foot box adds comfort in that critical zone. A mummy hood with draft collar and drawcord seals out cold air, and an anti-snag two-way YKK zipper can be opened from either end for ventilation control. The bag packs into an included compression sack measuring 16 by 9.5 by 9.5 inches (41 by 24 by 24 cm), and an interior stash pocket keeps small essentials accessible. Backed by a 2-year warranty.

What people are saying

Reviewers consistently praise the Klymit KSB 0F for its exceptional warmth, frequently noting it performs reliably in temperatures well below freezing, including single-digit conditions. The stretch baffles and roomy interior are standout features, especially appreciated by restless sleepers and larger individuals, with many recommending the oversized version for a better fit. The adjustable length locks and built-out foot box also earn positive mentions. The most common criticism is the bag's bulk and weight when packed, making it a poor fit for ultralight backpacking and better suited to car camping or base camp use. Some users also report zipper issues and durability concerns with the shell fabric after limited use.
