The MOJO 18 is an IP67 waterproof backpack designed for demanding sports outings. One goal: a bag that helps you finish the course and doesn't hinder your movement.

For cycling, mountain biking, gravel biking — an aerodynamic position without swinging
For long-distance riding, trail running, and day-long sports adventures, whatever the weather conditions
For water sports where you alternate between being in and out of the water
For outings where the bag needs to disappear during the activity

Description

The MOJO 18 was designed for bikepacking, sports adventure, and day trips where effort takes precedence over volume.

Its 500D high-tenacity polyester fabric, double-coated with PVC, is assembled using high-frequency welding: no exposed seams, no thread. The fabric forms an IP67-certified welded assembly. Special feature: the stitching points are rounded at the top, which prevents any right angles during compression — no tear points.

A fundamental ergonomic detail: the shoulder strap attachment points are offset towards the back of the bag, and positioned as low as possible. In practice, this keeps the bag glued to your back, even when you are leaning forward on your bike or running. Since the bag is narrow, it does not tilt sideways — whether you are in an aerodynamic position, running, or even swimming, the bag stays centered.

The back and shoulder straps are made of perforated EVA foam, with mesh on top. Air circulates (less sweat), water drains away (quick drying). No damp areas after immersion or intense exertion.

Roll-top closure at the top, with an option for side closure using buckles. If you close it at the top, the side straps turn into compression straps.

On the shoulder strap, an RCT buckle to attach the Phone Kit. The waist belt is removable (it slides into its pocket) and can be used separately — motorcycle tie-down strap, compression strap, emergency cord. The shoulder straps are detachable at the bottom: you can tuck them inside the bag to carry it in pure tube mode.

IP67 protection rating

IP67 certification and high-frequency welded construction: no seams, no threads, no weak points. Your bag can be submerged underwater for up to 30 minutes.

Stays stuck to your back, even in aero position

The shoulder straps do not attach to the top of the bag, but to an offset point towards the back and lower down. In practical terms: when leaning forward on a bike or while running, the bag follows your back. It does not tilt.

Perforated EVA foam — breathable back

The holes in the foam allow air to circulate — less sweat under the bag. And this foam doesn't absorb water: after immersion or exertion, it dries in a few minutes.

Hose with internal slide adjusters

You can tuck the straps inside the bag by sliding them in. Nothing sticks out anymore—useful on a bike rack, in an airplane hold, or for carrying the bag as a pure cylinder.

Rounded stitching points

At the top of the bag, the stitching is rounded. In practical terms: no sharp corners when you compress it. No stress points during use, even under repeated tension.

ZULUPACK Compatible Phone Kit

Integrated RCT loop on the strap. Your phone stays attached, accessible with one hand. Detach by rotating 180° and sliding down.

Pourquoi les bretelles sont-elles décentrées ?

Pour garder le sac collé au dos même quand vous êtes penché en avant à vélo. Le point d'ancrage des bretelles est positionné vers l'arrière et en bas du sac — cela empêche le sac de basculer latéralement et de tirer sur les épaules en position aéro.

Le MOJO 18 est-il vraiment submersible ?

Oui. Certification IP67 : immersion jusqu'à 30 minutes sans qu'une goutte ne rentre. Idéal pour les sports nautiques où l'on alterne dans et hors de l'eau.

18 litres, c'est suffisant pour quoi ?

Pour une sortie sportive d'une journée : bidon, outils, coupe-vent, téléphone, gel énergétique, snack. Pas plus — c'est un format calibré pour la performance, pas pour le transport. Pour un usage plus large, voir le TRITON 25.

Quelle différence avec le TRITON 25 ?

Le MOJO 18 est le petit frère du TRITON. Même ADN, mais plus compact (18L vs 25L), plus sportif (bretelles décentrées pour l'aéro), sans compartiment d'hydratation dédié. Le TRITON 25 prend le relais pour les sorties plus longues ou plus chargées.

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. "
