Decathlon’s Quechua Forclaz 50 Speed is a lightweight backpack with an internal frame and a fixed suspension. The backpack weighs 1080 grams, that is 700 grams less as compared with backpacks of similar capacity. Despite the lightweight construction the backpack is robust and comfortable over long distances. We have tested this backpack for 7 months and its comfort and robust build quality is impressive. This is one of the best backpack available in India for a multi day trek with a pack weight of under 15 kilos.
