Review summary

5L Reservoir is a handheld / soft flask (1500; 0 flasks). 5L Osprey Hydraulics LT reservoir — lightweight bladder for Duro/Dyna packs when you want continuous hydration without stacking front flasks. I'd shortlist it for designed for Osprey Duro/Dyna sleeve geometry.

5L Reservoir is the cleaner compare when that is most of your week. It fits buyers who actually need a handheld / soft flask (1500; 0 flasks), not a one-product rotation.
