The KSB 20s 650 fill power down top and synthetic fill bottom provides an exceptional warmth-to-weight ratio. Flexible Stretch Baffles keep fill next to your body and stretch when you move, while Length Locks™ allow you to adjust the bag to your height, creating a comfortable cocoon of fill around your feet. Additionally, anti-snag, two-way YKK zipper opens from the bottom or top to easily control the flow of air.
The size of this product is XL.
Gear Institue's Opinion:
"The Klymit KSB 20 is a light-weight, comfortable and super stretchy backcountry three season sleeping bag. The stretch baffle system allows for amazing movement inside the bag and the fair price tag for a down, three-season bag is something to rave about. One of the best parts of this sleeping bag is the stretch baffle system, as the horizontal sections are sewn with elastic thread making this bag “Super Stretchy.” An oversized foot box added to this comfort and allowed me to actually stretch tired muscles inside the sleeping bag. To say this bag allows you to move around easily is an understatement. The breathable shell fabric helped reduce condensation and dried quickly when condensation was present on the shell. The KSB 20 has more stretch than any bag I have tested. This really added a lot of comfort to the bag, allowing me to stretch out, move around and never feel encumbered. The 650 fill down is fluffy and comfortable."
