The new Jolla hydration pack from Hydrapak is a comfortable pack, with great carrying capacity, excellent features, the best reservoir in the business and the nicest designed set of pockets I have used. The Jolla is part of Hydrapak’s new Pro Series. The Pro Series constitutes their best design philosophy, features, materials and construction.
The foremost new feature for me as a longtime Hydrapak user, is that they finally solved their heinously leaky bite valve! The updated Surge Valve doesn’t leak, has a twist shutoff, an adjustable angled elbow, which bites and draws well, and just plain rocks. It can be somewhat difficult to operate the valve with gloved hands, but it’s a pretty minor issue.
The drinking hose also attaches with an innovative system called the Quantum Clip (no more Velcro), which uses a magnet clip on the hose, and an adjoining metal piece on the chest compression strap. It takes a bit of practice to get used to the system, but you just drop the hose clip easily on the proper spot with a distinct snap. It also prevents the hose from flopping around when you are bouncing along on rough terrain, which I had always found a bit annoying with hydration packs, in fact, I used to tuck the bite valve under the compression strap to prevent that from happening. One of Hydrapak’s statements about the Quantum Clip is, “keep your hose in check”, I am not even going to touch that one!
