>>2625188>I'd much rather have something like this in between my backpack / straps and my shirtare you retarded or something?
what psi do you think the air in there is?
probably atmospheric pressure
your pack is just going to squish it against your back, then its just a bunch of material to insulate and collect sweat. nasty.
>>2625137>>2625138fucking retarded beyond belief those fans probably move nearly 0 cfm and there's no way in hell they provide more cooling than the insulation of the vest itself.
just wear your clothes baggy and periodically grab your shirt and wave it back and forth to create a billows effect airflow.
keep it simple STUPID.
