Waterproof 48L trekking backpack for demanding hikes. Designed for long-distance walking, trekking, and travel, this unisex backpack offers a well-utilized 48L capacity, effective rain protection, and stable carrying for multi-day loads.

The bag's body is made of abrasion- and tear-resistant 420D ripstop nylon with a PU coating (3000 mm) and a polyester lining for enhanced durability. Exposed areas are reinforced, and zippers are protected by flaps to minimize water entry. The ergonomic back panel, featuring perforated foam and breathable mesh, creates airflow between the bag and your back, reducing heat buildup.

Measuring approximately 68 × 30 × 22 cm and with an expandable capacity (gusset collar and compression straps) of 45 to 52 liters, this bag easily accommodates a sleeping bag, clothing, cooking gear, and camping equipment. The main compartment is complemented by a separate bottom compartment for wet clothes or shoes, quick-access hip belt pockets, and a stretch front pocket. Despite its comprehensive features, the bag remains lightweight at approximately 1.25 kg, ensuring efficient carrying over extended periods.

Technical specifications and advantages

48L trekking volume: sufficient capacity for 2 to 5 days of trekking with optimized volume management thanks to the side compression straps.
Waterproof 420D ripstop nylon: lightweight fabric, resistant to snags, 3000 mm PU coating limiting infiltration in rain or sea spray.
Robust polyester lining: maintains the shape of the bag, provides better glide for packing and protects belongings from friction with equipment.
Ergonomic ventilated back: 3D foam panels and central channel promoting air circulation, reducing pressure points on the spine.
Air-cushion shoulder straps: dense padding, breathable mesh lining, high-placed load lifters to bring the center of gravity closer to the back.
Wrap-around waist belt: wide padded belt with zipped pockets for snacks, GPS or phone, better weight distribution on the pelvis.
Internal organization and dry/wet separation: top-loading main compartment with zipped bottom divider for wet clothes, shoes or sleeping bag.
Convenient external storage: side mesh pockets for water bottles, front stretch pocket for jacket or map, zipped top flap for small items.
Technical attachment points: loops and straps for walking poles or ice axe, lower straps for sleeping mat or compact tent.
Safety and night visibility: reflective elements placed on the front and shoulder straps to remain visible with a headlamp or headlights, SOS whistle integrated into the chest strap.
Adjustable carrying: height-adjustable chest strap, stabilizing straps on the waist belt, quick adjustments to adapt the bag to different body shapes.
Usage characteristics: suitable for hiking, trekking, backpacking trips and multi-day raids thanks to its combination of volume/weight/comfort.
Available colours: several understated outdoor shades visible in the photos: dark grey, brick red, dark green, black.
Dimensions and weight: approximately 68 × 30 × 22 cm, capacity 48 l expandable, mass of approximately 1.25 kg for a full bag.

Great but...

Delivery was fast, but the package arrived two days late due to a problem with the Post Office. The packaging arrived intact. We'll get a second one, which is very convenient.

Rather impressed

I'm impressed! Excellent outer material, with inner lining and separation between the upper and lower parts. On the semi-rigid side, the belt is not structured, but the weight distribution is effective and comfortable!

Alright

The backpack is great. It's large, has multiple compartments, and back support. The only downside is that the zippers were all open. Otherwise, nothing to report. Thank you, Antoine T.

Very good quality.

Very good quality. I am very satisfied with this sleeping bag. It contains a good amount of down and the zippers are of good quality. Perfect size. I am 1.89 meters tall and it is very comfortable for me.
