Very lightweight pack designed for high intensity mountain activities such as mountain biking could also be used for trail running.
Vaude says:
Double protection! This lightweight bike pack with 16 liters of carrying capacity protects your back and the environment. The eco-friendly manufactured material of this minimalist backpack consists of lightweight, siliconized 40D Rip-Stop while the outer mesh pockets consist of thin mesh material; even the shoulder straps, hipbelt and buckles were specifically designed to be extremely light in construction.
The outer multi-function drawcord system has a three-fold function: for compression, as a helmet holder and as additional attachment possibility, for a jacket, for example. The body-contact suspension system provides close-fitting carrying comfort on longer bike tours. You can stow an energy bar or gel in the shoulder strap pocket for a quick energy boost. With hydration system port and raincover in a pack sack. Green Shape is your VAUDE guarantee for eco-friendly products – made from sustainable materials and resource-conserving production.
Vaude's Uphill Rucksacks have a lot of room inside them for such lightweight packs, then you've also got external pockets and the compression cord for storing more things. Don't overload it however, as it is a very lightweight pack and it is not designed for very heavy loads.
You get a good quality elasticated pack cover with a loop for a light. It weighs 38g and is supplied loose in the pack so you don't have to cut it out like a lot of other packs do.
The Uphill packs are all certified Fair Wear Foundation goods, this means that you can be reassured you are choosing a pack that has been manufactured in an ethically sound, fair & supportive process.
