>>2010201He doesn't have it on his back all the time, I think the pic from
>>2009858 is an old setup and now he has it on the rear rack like pic attached and put it on his back when he feels like it's more optimal.
>In my case, even if I were using a seatpack I would still want to bring along a backpack anyway, as I like to do side-hikes when off the bike, and a hiking backpack is simply such a useful thing to have that I'd never want to travel without one. As a result, the weight difference is completely cancelled out for me. Having a backpack on the rack is super convenient as I can easily take it off and wear it during hike-a-bike sections. For the REALLY tough hike-a-bikes I can move almost all of the heavy stuff into the pack and onto my shoulders, making hike-a-bikes vastly more comfortable.
