Geigerrig Rig 500

Small, portable, capacity, maybe the air and water hoses are a bit "too cumbersome".

Notice:

Too small for day hikes, too big carry along a full mult-iday backpack (~45 Liters or more)

That plastic taste (and at the beginning, even odor) that comes with the water out of the hose. I have washed the bag, but most probably I will have to use food grade detergent to clean it once and for all. The manufacturer recommends to wash it thoroughly and to store for an entire night water with a whole lemon juice to remove the odor. The product (at least the water bag) claims to be BPA and PVC free and food grade material; however, the flavor tastes like a really strong plastic component (indeed, medical grade polyurethane). I haven't tried it, but seems to be a typical issue with this hydration packs from any other manufacturer (i. e. C@melb@k).

Fit: The straps are adjustable but for me (170 cm tall and not athletic) where always a bit short and hard to set and remove.

Comfort: Hip belt and shoulder and sternum straps are adjustable and comfortable. I didn't for too long, but even on hot weather it felt great.

Capacity: For water and some other stuff, it's more than enough. Just don't put too many things inside, once the water bag is full everyghing will be cramped.

Organization & Accessibility: Zippers are durable and secure.

Ride: For the small amount of cargo, it's evenly distributed and comfortable.

Compression: It adjusts well, however, to wear it and to remove, it could be a bit hard.

Ease of Use: Once you figure out how the Hydration Engine works, it's pretty straightforward.

Features: Fully pressured, it works as expected. 

Construction & Durability: Having seen many backpacks over time, I can compare it to the quality I would find in an Osprey brand equipment, made to last.

Conditions: I just used it for travels with the family, no more than one or three hours urban hiking around towns.
