Helium V5 is the latest generation in a backpack family that has ventured to all corners of the world (including the three poles) – a family that is the top choice for both experienced polar explorers and regular hikers. Helium V5 features an incredibly robust, ultra-lightweight, and durable material. The combination of adjustable back length, comfortable shoulder straps, and a contoured hip belt provides a pleasant carrying experience. If you want to carry really light, you can remove the hip belt and the lid and combine them into a waist pack. This is a versatile and highly functional outdoor backpack, just as it has been throughout its 20-year career.
