Caving Kit Bag Aventure Verticale 40L PVC

The tube format is not an aesthetic choice — it is a functional response to the geometry of vertical caving. The bag is fabricated in Cholet (Maine-et-Loire, France) from 1100 dTex varnished PVC canvas at 900 g/m², the most abrasion-resistant fabric in the AV range, designed to scrape limestone and sandstone walls without wearing through.

Recommended uses

Designed primarily for caving expeditions in Britain's classic systems — Yorkshire Dales, Peak District, South Wales karst — where vertical pitches and tight meanders demand gear that moves with the caver, not against them. The 40 L capacity suits full-day rigging carries, while the Hypalon-reinforced base handles the scraping that any kit bag accumulates on a long wet pitch. Also suited to rope access (material transport), underground dive operations (oxygen cylinder transport) and technical canyoning in wet environments.

AV range positioning: the 30 L tube (AVSP35) is the lightweight prospecting companion; the 40 L (AVSP36) targets full-day expeditions with rope and rigging kit; the 45 L (AVSP32) covers multi-day stays and group equipment carries.

Key strengths

• Cylindrical tube format: 75 cm height and round cross-section thread through low passage and rebelay points that stop rectangular bags dead
• 1100 dTex PVC canvas: heavy-duty fabric weight resists abrasion against rough limestone, sandstone and volcanic rock — outlasting lighter-canvas alternatives
• Hypalon base reinforcement: maintains oval floor geometry under load and absorbs repetitive contact damage on cave floors
• 60 mm padded shoulder straps: wide load distribution across shoulders during haul and scramble sections
• Included lanyard + base rings: clip directly to a belay point at the head of a pitch; link two bags with a carabiner for large group equipment carries
