I would not use these for international travel. I got flagged for explosives at an airport and the seams of the bag tested positive for a compound that is commonly used in plastic explosives. Almost made me miss a flight, and if I wasn't a fairly harmless looking white guy, I'm sure it would have been much less fun...
To elaborate the bag was brand new, and I was using it as my "personal item" on a flight. There was nothing in it but my camera, phone, book, and a couple random snacks. They dumped the whole thing out and after swabbing all the items determined that the bag itself was what was alerting the systems, and advised me not to use it anymore.
JoeweeHi Joewee - I'm not sure what to say other than that your experience appears to be isolated. I've heard from dozens if not hundreds of customers who use their Bindle for international travel and have never had this happen. I can't even begin to take a guess as to what could have caused the test to fail (or whether it was a false positive) but I do know that there's nothing used in the construction that should cause any issues and I've flown with my bag personally many, many times. We stand behind all of our gear so if you'd like to send it in and have us send you a replacement I'd be happy to do that for you - just drop us a line at hey@treklightgear.com and we'll help you out.
