Description

The TUBE 45 is designed as a high-capacity waterproof bag, intended for demanding marine and outdoor environments.

Its high-tenacity 500D polyester fabric, double-coated with PVC, is assembled using high-frequency welding. In practical terms, there are no exposed seams, no threads, and no weak points. The fabric forms a welded unit: water has nowhere to infiltrate.

Its cylindrical structure is self-supporting. The bag stands upright even when empty, which makes loading and unloading easy. The reinforced base allows it to be placed without caution on a boat deck, sand, or rock.

Carrying is handled by two ergonomic shoulder straps, an adjustable chest strap, a front handle, and a top handle integrated into the roll-top. The bag can be worn on the back for occasional walks, or secured directly to a motorcycle, kayak, or luggage rack.

Le TUBE 45 flotte-t-il ?

Oui, s'il est correctement fermé et contient de l'air. C'est une sécurité utile en bateau ou en kayak — votre matériel ne coule pas.

Est-il confortable chargé à 10–15 kg ?

Oui pour des marches occasionnelles, grâce à ses bretelles ergonomiques et à sa sangle pectorale. Ce n'est pas un sac conçu pour le trek longue distance : il est avant tout pensé pour le transport étanche.

Y a-t-il une poche pour ordinateur ?

Non. Le TUBE 45 est conçu pour le milieu marin et outdoor : un grand compartiment principal, étanche, optimisé pour le volume et le chargement rapide.

Comment se fixe-t-il sur une moto ou un kayak ?

Le sac dispose de points d'attache latéraux compatibles avec des sangles ou des tendeurs. Les bretelles ne gênent pas une fois le sac fixé : il devient un cylindre étanche stable.

Excellent quality

The products are exactly what I expected. They arrived perfectly packaged and on time. Excellent quality, and they meet the waterproofing specifications. An excellent experience for a first purchase; I highly recommend them.

Very comfortable on the back.

"I bought my 25L waterproof hiking backpack to withstand the weather conditions at the 2024 24 Hours of Le Mans, and I wasn't disappointed. None of my clothes or electronic devices were affected by the rain, and it was very comfortable to wear. I highly recommend it."

Really very strong.

"Really great bags. I have the Rackham 60, which I use all year round as a gym bag, and in the summer as my bag for carrying my wetsuit and triathlon gear. Very good quality and really sturdy. Lots of space. I can fit my wetsuit, shoes, and bike helmet in it without any problem. "
