The KAIPAK 38 from Fjll Raven is a simple, lightweight and rugged backpack for day or two trips.

It's made from durable G-1000 HeavyDuty Eco fabric in recycled polyester and organic cotton, which can be coated with Greenland Wax for even greater resistance to moisture and wear. The backpack is fitted with a fixed, stable , rear-length carrying device adapted to the dimensions of the backpack. As a result, the backpack adjusts perfectly to the athlete's back, especially as the waist belt and shoulder straps wrap perfectly around the body's contours. The waist belt even includes two pockets to keep important belongings close at hand. Featuring a top opening with top flap, this bag has a spacious main compartment and a snow protection system.

There's plenty of functionality, too, with an attachment loop for ice axes and trekking poles, a front zippered pocket for rain gear, two side pockets, compression straps on the sides, a whistle on the chest strap and waterproof protection in high-visibility color, not to mention compatibility with water pouch systems.
