Straight backs are happy backs! Kånken was created as early as 1978 to help prevent back problems among Swedish schoolchildren and quickly became commonplace in preschools and nature schools across the country. Today, 35 years later, Kånken has straightened millions of backs around the world and has become one of Fjällräven's most beloved products. This classic backpack is suitable for both trips to and from school or work, as well as hiking and traveling. The material is durable, lightweight F Vinyl fabric that is able to withstand dirt and moisture. The spacious main compartment has a large zipper opening, making it easy to load and unload the backpack. It has two flat side pockets and a zipper pocket on the front, perfect for those bits and bobs you want to keep close at hand. The included PE foam seat cushion stores in the interior back pocket, where it prevents the backpack's contents from banging against your back, and is always within reach for when you need to take a break and sit down, whether you're where you are. The carrying system is simple but practical and consists of handles on the top and thin, adjustable shoulder straps. The logo on the front is reflective. It also has an address label inside the main compartment.
