The Hydro 3 has been designed specifically as an active riding pack with Kriega's unique Quadloc harness system. Providing a level of fit and comfort unequalled by any other hydration system, with a fully adjustable back-length and unrestricted underarm movement. Once set, the pack is exceptionally convenient to use, with none of the harness strap re-adjustment necessary on conventional harness systems. The adjustable back also allows the pack position to be moved up to allow large waistpacks to be also worn. Hydro 3 can be worn with or without a waiststrap - Kriega recommends using the waiststrap for maximum stability, when carrying the full 3 litre (100 oz) water capacity.
1-litre side access zip pocket
Shock-cord for external storage
Removable waist strap
Unique QUADLOC harness: adjustable back length with total arm freedom

Jason K:Yes, the bladder from the Hydro 3 is 100% compatible with the R25. The exact location of the hydration bladder depends on which R25 you have. From the Kriega website: "When installing in a pre-May 2013 Kriega R25 motorcycle backpack, the reservoir fits in the outer pocket with the drinking tube being routed out of the top of the zip and over the shoulder. On the current R25, the tube has a dedicated, covered duct in the top center of the main compartment that the tube can be fed through."Jan 25, 2014
Rhett V:The r25 backpack does have a space for the hydration bladder which can be purchased separately. I have this hydro 3 backpack for trail riding and use an r20 for commuting. When I go on a long ride I just swap the bladder into my r20 so I have hydration as well. You could do the same with the r25.Jan 25, 2014
Daniel H:Mostly. I use it in mine throughout the summer. It fits in the back, side-opening pocket just fine. The only issue is the hose could be a few inches longer to work better. It works, but would be a lot better if the hose were longer. It gets better as the bladder empties too.Jan 26, 2014
Eric C:No, it has its own harness. The bladder is very nice, 3 liter, and can be used in the R25. I guess you could strap it on to the outside of the R25 or R30. The quality and design is the best.Jan 25, 2014
