Fully taped roll-top dry bag which is shaped to fit into tapered spaces, such as our Koala seat pack or a kayak bulkhead.

Just like the rest of the Airlok XTra range there are attachment points either side of the bag. Extra utility comes from the sewn-in webbing strap which extends around the length of the bag opening up a multitude of additional attachment opportunities.

Note: This Airlok will fit perfectly inside one of our Koala seat packs. If you want the lightest possible set up it is also possible to attach it directly to the seat post as a lightweight saddle bag. However be aware of its limitations: sitting underneath your seat it will be exposed to constant abrasion, mud and grit which may eventually wear holes in the fabric. Other options include systems such as the WildCat Tiger padded harness.

Definitely fit for purpose!

I rode from Ireland to Cornwall with this bag and had no problems. I used a velcro strap to attach to the seat post and two straps, one to the top of the seat post and the other under the saddle rails....didn't budge and inch over a few hundred miles. Usual great built quality you expect from Alpkit....well done.

Great value

Amazing piece of kit for the price. I used whilst doing the Cairngorm Loop over 4 days. My recommendation is to get an extra strap or 2 to help eliminate the wobbles and to keep it wedge shaped just under the saddle.

Not fit for purpose

If you want a 'lightweight luggage solution' as the picture states don't waste your money on the airlok. I have yet to find a way to attach this bag to my bike in a way that is satisfactory. I have tried adding velcro straps, zip ties and bungees but all fail to stop the bag moving around. If you attach it to your bike as Alpkit have suggested the movement and instability is simply laughable. I think someone at Alpkit needs to reword the blurb on this bag and remove the misleading photos. Quite simply I now have two unwanted drybags and am £42 poorer for it!

Awesome lite low cost option, recommend

Was doing a 1000k Bikepacking Event in New Zealand, had a bigger seat bag but wanted to go smaller, lighter = faster. Know this isnt really promoted to have heavy use by itself but used it for the event and worked awesomely! Did leak a little but that was after 10hrs riding in the wet and by the end of the event did have a small tear on the daisy chain loop where sat between the seat rails but considering the use i'm happy. Will get it repaired and think will just run an extra webbing loop around the bag and seat rails but not the daisy chain just to give it a bit of extra support for next years 1100k mission. Oh yeah, i used it for training missions beforehand.
