I have 4 total Bottle holders.  I have two 20oz and two 32oz (Nalgene size) HMG bottle holders.  They are designed to attach to their Porter Packs, but they could work for other applications as well.

One of each are still in the wrapper and one of each has been removed from the wrapper, but is still as new.

These are $30 each from HMG plus shipping.  Send me a message if you are interested in buying any or all of them.

Thanks  Adam
