Same here. Partly for cost issues, buying a nice bag and preparedness gear is expensive so getting use out of it helps ease the cost. Sure you can buy cheap stuff but it helps to justify more expensive stuff if I get more use of it.
I found a modular pack so when just going on a simple bike ride I can remove two layers and have just a hydration bladder and psk and the additional gear is in the truck where is supplemets the get home gear. Then if going on a hike I can add on a layer or two.
