Pleeeeeese!!!!!! I am currently using an eBay Smart Alec. I’m able to clip my Thermarest sleeping pad: a featherweight travel essential -with the compression straps. (BTW-Thermarest=sleep in airports; adds structure to bad mattresses, seating pad, beach pad, etc.)
There is absolutely no good reason why a few lash loops can’t be conveniently included strategically around the bag. Even just at the bottom-anybody remember lashing a sleeping bag to the exterior bottom of a framed backpack? Plenty of uses: flip flops, tripod, walking poles, monopod, bulky jacket.
God forbid we should be able to rig a bungee chord on the outside of the bag! We’re talking about perfecting a minimalist, one bag travel tool. Come on guys.
