Comments about Camelbak FlashFlo 50 oz. Hydration Lumbar Pack:

When full this pack can begin to get top-heavy almost to the point of potentially toppling over. This is remedied by rearranging the contents of the pack and making sure that the bladder/water is in the bottom of the pack. Easier said than done once this thing is strapped on, though (I strap the bag on my back with the strap on my stomach, and cannot easily access the contents in this configuration). My main beef is that if you wear it this way, the strap can be uncomfortable...I just put a towel inbetween it and me, which looks a little dorky but does the job. Otherwise I am thrilled with the product. ALSO note that the tube can be extended (seems a bit short) by rerouting the tube to the opening on the other side (same side as how it comes out of the bladder). When you first get it the tube is routed out the opposite side of the pack, making it shorter.

Love the lumbar hydration packs. This one is too bulky. The Alterra is the perfect size,I assume it is no longer available as I have been unable to find one.
