Just a tiny warning to those consider Billingham and Brady rubberized canvas as somehow better than the other types of canvas available elsewhere. I have handled older Billinghams and they do show delamination. Billingham has acknowledged this in the past (circa 2011?) that the rubber will delaminate in older bags, and will harden/crack/deteriorate over time. In our climate, this process is likely to be more accelerated. Once you see delamination, it is likely that the bags will not be waterproof (or stormproof as Billingham calls it). Also, if you do buy Billingham camera bags, the warranty is on the bag itself and not on the foam inserts. The foam inserts will disintegrate and you will need to replace them on your dime.
Here is the new Hadley One. The Hadley now has a carrying handle. The shoulder strap comes with a shoulder pad. The laptop sleeve is now fixed but still lightly padded. The camera inserts can be fastened down. The rear zipper is a YKK rainproof one. Importantly, it now has a luggage pass through for luggage handles so that one can have brief moment of respite for those aching shoulders while trying to look cool jetsetting. I hope I resist the temptation to go to the store to see it.
