[Hectic]

prety much any "stand alone" hydration can be rigged up to prety much any rig or pc, just need some zap straps/zip ties and or duct tape and yer gtg.
also i should note that a stand alone (like the condor one thats covered in webbing) has removeable straps and has the molle straps to attach it to a PC. And also the same condor one has super skiny straps and if u put it on under a chest rig youll hardly notice its there
