Somebody had to think of it, and inspired by crash-pad design, it was SNAP.The shoulder straps stay clean! They never come into contact with the ground ! Like the crash-pads! At the foot of the climbs a large opening gives easy access to the contents, and the double handles make it easy to move from climb to climb.Keep your climbing shoes and chalk bag separate in the two zipped lateral pockets, and keep your rope clean by using the separate ground sheet (1m40 by 1m). The base is in tarpaulin that can be sponged down, the sides are in polyester, the shoulder straps are ergonomic and padded with EVA foam, there is a chest strap, two carrying handles and the raised felt SNAP logo – to remind you of comfort, practicality and quality.
