You’re not going to let a spot of rain stop you from Going Nice Places and Doing Good Things, especially when the Airlok Dual is around.

Inspired by our Airlok range, the Airlok Dual drybag provides waterproof handlebar storage for your two-wheeled adventures, ideal for light and bulky items.

Waterproof TPU fabric and fully taped seams keep your gear protected from the elements, dual-ended roll top closure gives you convenient access to your gear whilst keeping out the rain.

Although designed for use with a harness, Airlok Dual can be attached directly to your handlebars for an ultralight set-up. However as the fabric is less abrasion resistant that VX21, this may wear holes in the bag.

Airlok Dual uses black 20 mm Stealth buckles which are incompatible with the 20 mm Duraflex S.J. buckles on the Roo Pouch or Kanga handlebar harness; new straps are available as Dual Straps.

Airlok Xtras have changed! Well, kind of…

Our Airlok Xtra, Dual, and Tapered dry bags are now lighter, with minimal sacrifice to durability. You'll find that they're more supple and less beefy than previous incarnations, but don’t panic! They’re still durable, protective, and as adaptable as they always have been: the same, but different!

Airlock XTra dry bag

Excellent personal service, delivery was prompt, dry bag works and fits brilliantly, easy to fit and doesn't move around, would use again. Thank you Alpkit.

very well made

This is a VERY well made bag, simple but you can feel and see the quality - it actually feels really good to touch! wink
I use it to carry my sleeping bag on my gravel bike, it fits very snugly.

20L Airlok Dual dry bag

very well made looking forward to putting it to use great size well done again alpkit.

Airlok Dual 20ldry bag

The quality of the materials is good and the bag it's really well made: i think it will last for a very long time.
The real capacity is not 20L because you must fold the ends, but it's not a big problem because you have about 15L usable.
For a offroad usage i recommend the alpkit support kanga or you can add a pair of straps in the correct points, so you will make the bag completely stable.
In the end, considering his price, I totally recommend to buy this bag!
Thanks Alpkit for this amazing product!

Great handle bar bag

I used this for my sleeping bag on a recent 5 week trip to Patagonia. I never had a problem with it. It remained water tight the whole time even in some heavy Patagonian down pours with gail force winds, totally bombproof! The only thing I realised while I was away, I probably didn't need the double end access because it was only my sleeping bag. I could have used a standard 20L dry bag from Alpkit. However it's good to have the option, as in summer my bag is smaller which would allow me to pack my down jacket in there as well. Always good to have options smile

A great handlebar bag.

It does exactly what it's supposed to.

Having the dual closure definitely makes it a lot easier than a normal dry bag where you may struggle to get all of the air out while packing and certainly helps you to pack more evenly, packing the sleeping bag in the middle and then balancing smaller bits in each side.

There's plenty of room within as well. I manage to fit a 3 season bag, hunka XL bivvy bag, Cloudbase mat, a pillow, head torch, tarp, long sleeved shirt and hat within mine, and I'm sure I could get a bit more in if needed.

This thing is huge!

The bag has more then enough carrying capacity when mounted to the handle bars, could fit loads of stuff in it
