Product Description

The Big River Dry Bag Keeps Your Gear Safe and Dry

With the Sea to Summit Big River Dry Bag, your gear stays dry on every adventure – whether on water or land. Made from durable, abrasion-resistant 420D nylon fabric, the Big River Dry Bags reliably protect your equipment from water. Perfect for kayaking, canoeing, rafting, or land activities like bikepacking and motorcycle trips, these bags are your ideal companion.

The white inner laminate improves visibility, while attachment loops allow secure stacking or fastening to vehicles and gear. The Hypalon roll-top keeps moisture out, and the Field Repair Buckles can be quickly replaced with a Phillips screwdriver if needed. The oval bottom saves packing space and prevents the bag from rolling away.

Product Features:

  • 100% waterproof, double-stitched, reinforced, and taped seams
  • Multiple attachment points allow versatile mounting on kayaks, bikes, motorcycles, and off-road vehicles
  • Improved visibility of your gear thanks to the white inner laminate
  • Attachment loops for stacking or securing to vehicles and gear
  • Hypalon roll-top: waterproof and reliable, keeps moisture out
  • Practical Field Repair Buckles (buckles on the roll-top that can be quickly replaced with a Phillips screwdriver)
  • Oval bottom: saves space when packing and prevents rolling
  • PFC-free

Review with rating of 4 out of 5 stars

Robust, aber ohne Ventil etwas unhandlich

Die Haltbarkeit ist top, Material super stabil und für Gravel-Touren bestens geeignet. Einziger Minuspunkt: Ohne Ventil lässt sich die Luft nicht rausdrücken, dadurch manchmal sperrig.

Sehr robust, aber etwas schwer

Im Vergleich zu anderen Dry Bags ist der Big River kein Leichtgewicht. Dafür hat er schon einige Stürze und unsanfte Bodenberührungen überlebt – hält also wirklich was aus.

Unverzichtbar fürs Bikepacking

Ich nutze den Big River seit über einem Jahr auf Radreisen. Egal ob Regen oder Flussdurchfahrt – alles bleibt trocken. Besonders praktisch finde ich die Befestigungsschlaufen für den Gepäckträger.

Mein Favorit für längere Touren

Ich transportiere darin Schlafsack und Ersatzkleidung. Der Sack sitzt sicher oben auf meinem Gepäckträger und hat auch bei Dauerregen dichtgehalten. Absolute Empfehlung für Bikepacker!

Hält bombensicher dicht

Ich habe mehrere Größen im Einsatz. Ideal, um Ausrüstung an der Gabel oder am Gepäckträger zu verstauen. Das Material ist nahezu unkaputtbar.
