Ferrino X-Dry 15+3 is a trail running rucksack that is perfect for running in all weather conditions. Thanks in fact to the HDry membrane, this backpack is completely waterproof with 10000 mm of water column even at the seams. It is very comfortable to wear thanks to the height-adjustable shoulder straps and the HBS "Hollow Back System", which combines padding with ventilation channels and quick-drying 3D mesh to promote breathability and heat dissipation. There are several pockets inside which you can organise all your equipment: two elasticated front pockets, two for water bottles on the shoulder straps, one front pocket with zip fastening, one rear tunnel pocket with double access, one on the back with external access for storing your hydration system, one on the waistband, and one internal mesh pocket for small items. The roll-top closure is also completely waterproof, allowing you to increase the volume of your new backpack by 3 litres. You can also easily carry your poles thanks to the set of elastic bands.
