    Finntrail EXPEDITION 40L Black 1730 Backpack

    A hermetic 40-litre backpack with welded construction and a roll-top closure that keeps water fully out and protects your gear on expeditions, travel and bad weather. The maker calls it hermetic: welded seams and a roll-top closure form a sealed interior, so water, mud and moisture stay outside. The durable 350 g/m² material withstands rough outdoor use, while the roomy 40 l main compartment and practical pockets hold all your travel kit. Ergonomic shoulder straps let you carry it long and comfortably, and the material works down to −10 °C, so the pack serves in every season.

    Who it is for

    Made for expeditions and travel in any weather, when your gear has to stay dry and clean while the pack takes on mud, rain and cold.

    • •For anglers and outdoor enthusiasts travelling through wet and mud.
    • •For expeditions and hikes where keeping gear dry matters.
    • •For all-season use, including cold conditions down to −10 °C.

    When it shines

    Best in wet and bad weather, when keeping your gear dry matters most: the roll-top closure and welded construction keep water out, the durable 350 g/m² material takes rough use, and the 40 l capacity holds your expedition kit.

    Materials & technology

    Hermetic roll-top construction

    Welded seams and a roll-top closure form a sealed interior, so your gear stays dry in rain and mud. The maker calls it a hermetic backpack. Rolling the top correctly keeps the inside dry.

    Durable 350 g/m² material

    The dense 350 g/m² material withstands rough outdoor use: abrasion, mud and moisture. It works down to −10 °C, so the pack serves in every season.

    Capacity and comfortable carrying

    The roomy 40 l main compartment and practical pockets hold your expedition kit, while ergonomic shoulder straps let you carry it long and comfortably.

    How it differs from a cheap bag

    A cheap bag or sack

    • Stitched seams let water seep through
    • The inside gets wet in rain or mud
    • Thin material tears quickly
    • Straps dig in and wear out fast

    Finntrail EXPEDITION

    • Welded seams, sealed construction
    • Roll-top closure keeps the inside dry
    • Durable 350 g/m² material
    • Ergonomic straps for comfortable carrying

    Care

    Wipe clean with a damp cloth, rinse caked-on mud with clean water and do not machine wash. Dry it open at room temperature. Restore the water repellency with an impregnator (Mountval Textile Shield), especially on the bottom and the seams. Do not store it folded while damp, so the material and the seams last longer.

    Frequently asked questions

    Is it really waterproof?

    The maker calls it a hermetic backpack: welded seams and a roll-top closure form a sealed interior, so your gear stays dry in rain and mud. As with any dry-bag design, you need to roll and clip the top correctly.

    What is the capacity?

    The main compartment holds 40 litres, plus there are practical pockets for smaller items. That is enough for expedition or travel kit.

    Does it suit cold weather?

    Yes. The material works down to −10 °C, so the pack serves in every season, including cold winter weather.

    Is it comfortable to carry far?

    Yes. The shoulder straps are ergonomic, so the pack is comfortable to carry for long stretches, even with a full 40 l load.

    Is this the same as the 1719 model?

    No. This is EXPEDITION 40L 1730 with a hermetic roll-top construction. The 1719 is a separate model with an IP66 rating. If unsure which fits your use, message us and we will help.
