Pre-order
If we don't have a specific item in stock, you can still place your order. Pre-order items will generally ship within 3-4 weeks, provided that we have your selected fabric choices in stock for manufacture.
In stock items will generally ship within 3-5 working days.
Special Edition Items
If you have selected a special edition item, you'll be able to choose a unique combination of colours for a completely custom look. Mix and match any available colour swatches to any panel of the bag - the shape remains the same, but the colours are up to you! We'll communicate with you via email as to your specific requirements. Due to the extra work involved, it may take us longer to complete your order.

Made with lightweight, waterproof 30D Ultra-Sil fabric featuring CORDURA® yarns, it's the perfect choice to organize your gear inside your backpack or duffle like a pro.

Which dry bag is right for me?
This depends a lot on what you intend to use the dry bag for. The Sea to Summit Big River Dry Bag is well suited as an all round versatile dry bag for particularly wet conditions, overland expeditions or when your adventure includes water/paddle sports. It will fit comfortably in our ROBO-KIWI harnesses, but is shorter, wider and heavier for its volume compared with ROBO-KIWI dry bags. For the best bikepacking-specific dry bag, we recommend using ROBO-KIWI double-ended dry bags as they have been specifically designed for fitting on bike handlebars.

For internal organisation and modular packing inside your front bag or saddle bag, we recommend using Sea to Summit Ultra-Sil Compression Sacks and Sea to Summit Ultra-Sil Dry Sacks.
For temporary extra storage on longer multi-day rides, brevets or bikepacking races where you need to periodically resupply or a lightweight summit day, we recommend the extremely compact and ultralight Sea to Summit Ultra-Sil Nano Day Pack.
Waterproof?
Yes, in situations where the dry bag will not be submerged.
