For sale are two small camelbaks in pristine condition (smallish, 1-2L size) and two bladders in good-used condition.

The packs ($20 each or $35 for both):
I am unsure of the model names here but both are roughly comparable to something like the Hydrapak. The slightly smaller one is in a “hers” color palette — gray on the front and pink on the back. The larger one is more of a unisex palette (red).

Bladders:

Both are a few years old, but have very little wear, and have always been cleaned after use. No strange stuff growing inside.

1. Smaller one (50 oz / 1.5L) is Camelbak brand, older “Omega” style but comparable to this 50 oz model. Hose is insulated and bite valve has a lock mechanism. [$10]
2. Larger one (100 oz / 3L) is the first gen. “Hydraform” model from Osprey which has an integral framesheet for rigidity, and a magnetized bitevalve which sticks to your sternum strap (if you have some metal there). Bitevalve also locks and rotates. A little bit heavier than e.g. Platypus, but a nice bladder. [$15]
