Hiking Hydration Running Backpack Men 5L Camping With Water Bottle MTB Cycling Backpacks Men's Breathable Marathon Bag Equipment

I have had one of these for about 3 years. The front strap pockets are super convenient for carrying a phone on one side and a couple snacks/plug kit in the other. Its not obnoxiously large but it carries a pretty good amount of stuff and you can fold up discarded layers or pick up trail finds in the mesh net that folds up into the hideaway pocket on the back bottom.
