Backpacks are getting a undeserved bad rap imo

In fairness your example is extreme and minority not average nor majority
My post was in reference to the masses riding bicycles. 

modern cycling specific backpacks allow more airflow for sweat to not accumulate than ever before   Add in lightweight - load and they are a pleasure   

Many things make one sweat before the backpack is to blame - outside temp , humidity, ones output how hard they are riding and for how long , the Jersey and helmet choice , what they consumed prior 

For me , my experiance the more and/or larger bike bags, racks etc  I add to my nice bicycle the uglier and worst handling , less sporty and fun it gets   Aside from my repair kit if I would like to bring 5 pounds of clothes or whatever I MUCH prefer a modern backpack and find it MUCH more useful , non specific than all the bike packing , touring bags   

if it’s hot and humid and I don’t want to sweat as much I slow down my output   

If I REALLY  didn’t want to sweat, reduce sweat  I would start with  not wearing  a shirt / jersey nor a helmet 
and have full airflow

btw - I remember not long ago when “ Gravel Grinding “ was more a culture activity rather than performance , race , event driven and “” Gravel Mutts “” was the common name for cycles used. 

sadly I seen MTB’ing go the same way especially in the early 90’s

Then comes blood doping to achieve ones best  

sad …..

Thanks for sharing your find Jack 1112

Nice Link ( above) looks good !

fwiw - it’s cool here in Va. March 1 and I am very much enjoying riding my bike locally , often , with my modest bicycle specific backpack and typically some soft goods in it - and just a tool/tube bag under the saddle & cage bottle holders. Occasionally I do pack my laptop ( hardgoods) but mostly I use my phone
