The Air-Tight Technical Duffel
The Kukuna® 40L Duffel is a high-performance waterproof bag (IPX6-rated) featuring an air-tight waterproof zipper and an integrated air-release valve. This valve allows users to expel air for compact packing or trap air to fine-tune buoyancy - a critical feature for sailing and boat-to-shore transits. It includes an integrated bottle opener for post-session utility.

Frequently Asked Question
Q: Does the 40L bag have a zipper or a roll-top?
A: The 40L model uses a 100% waterproof, air-tight zipper for faster access and a sleeker profile than traditional roll-tops
Q: How does the air-release valve help with packing?
A: The integrated air-release valve allows you to "burp" the bag after it is zipped shut. By expelling trapped air, you can compress the duffel to fit into tight spaces like boat lockers or airplane overhead bins.
Q: How do I maintain the airtight waterproof zipper?
A: The 40L Duffel features a specialised pressure-sealed zip. To keep it sliding smoothly and maintaining its airtight seal, we recommend rinsing it with water or a damp sponge after a day near salt and sea.
Q: How do I clean the recycled PVC fabric?
A: The PVC surface is non-porous and easy to wipe down. Use a soft sponge and fresh water to remove mud, salt, or fish scales after a trip on the water.
