The S series is a range of medium-capacity rucksacks offering generous volume at a sub-kilo weight. The S series employs an ultralight frame unique to Lightwave (but which has flatteringly spawned several lesser imitations!). Combined with a generous wrap-around hip belt, it provides a comfortable and stable carry for loads of 12-15 kilograms.
Even though the S-series rucksacks weigh in at less than one kilogram, they are constructed with robust fabrics and retain a functional range of features.
The S series is available in three sizes, 42, 48 and 54 litres, with each size available in three back lengths
