First off, i dont ever rate anything perfect because nothing is ever perfect and thats why i rated this a 4 instead of 5 stars. To start with, the quality is excellent and it does whats its suppose to, holds a water source or equipment. My only complaint is that it can be a little pain to get into your chest rig with this attached due to the fact most of TAGs chest rigs are not open front. Its even harder with a full armor carrier on then without. Another thing is the buckles that are on TAG's chest rigs. They are not fully removable and you end up with buckles dangling on your shoulders when your not using the H20 carrier. If tag wishes to incorporate this product for their chest rigs they need to remake their line of chest rigs and h20 carriers. What i would like to see in the future is the chest rigs waist straps be ambidex to make it easier for don/doffing the chest rig when using h20 carrier. also, Change the h20 carrier waist strap as well to match the newer waist straps. But as far as the product goes, its good to go if you really dont mind the chest rig as is and you want a h20 carrier to go with it. it all works decent, but if tag wants it to be better and excel they should take this review into consideration.
