Klymit KSB 20 Oversized Down Sleeping Bag Review

A little extra empty space inside your sleeping bag becomes a trap for cold air to gather and can adversely affect you in colder conditions. Klymit’s redesigned KSB 20 Oversized bag is very comfortable and engineered with a flexing baffle design that provides some extra volume without the extra dead space.

Specs

The KSB 20 Oversized weighs 3.1 lbs (1.4 kg) and measures 82″ x 40″ (208 cm x 102 cm). It is rated down to 20 F (-7 C). The material used is a hydrophobic 20D super soft rip stop nylon that is silky soft and won’t absorb moisture.

The exterior is treated with durable water repellent or DWR.  A 650 fill-power White Duck Down insulates the bag for excellent 3-season warmth. The Down is lofty and the bag compresses down very well, small enough to chuck onto a hiking pack. At 3.1lbs it’s worthy of any car camping trips but not impossible to hump out for shorter hikes to set up camp.

Design Features

Klymit’s new KSB 20 bag features a flexing baffle design that allows you a bit of freedom to move without creating dead air space inside your bag. The baffle design does very well to keep the Down from bunching up and keeps it evenly spread out.

The Chest area of the KSB 20 is oversized while the foot box is designed with a half-moon shape to retain warmth tweaking out the comfort level. Additionally the bag incorporates a mummy hood for maximum warmth when the temps drop at night.

Klymit KSB20 Oversized snag-Free Zipper Head

A 3/4″ full length zipper has a little oversized head on it which is supposed to make the zipper snag-free. It does seem to work a little better than a traditional zipper but try to do it quickly and it will still get caught on the full length zipper guard layer.
