Carefree traveling: extremely lightweight trekking backpack for trips where every gram counts. Our lightest mid-volume backpack for trekkers and journeys weighs less than 900 g. It is made of lightweight, rip-stop siliconized 70D ripstop and a rugged 200D material at the bottom and the sides. The weight-optimized Tergolight suspension system can be adjusted individually to the back length and provides a good fit and high wearing comfort. Our smallest Zerum is best suited for shorter people to about 175cm. Side straps and a user-friendly packsack under the lid make it largely compressible. The front compartment with breathable mesh inserts is also particularly suitable for wet items like raincoat or rainfly because moisture can evaporate. Everything that should be easily accessible, can be stowed in the side, large-volume, stretch mesh pockets. Even a drink bottle or cap can be quickly accessed, without taking off the pack. A versatile, very strong cord serves as a functional option for attaching trekking poles and additional gear.
