I haven't used the Transformer but I have used the H.A.W.G. quite extensively and have been thouroughly impressed by the design and forthought put into this bag.<br><br>http://www.camelbak.com/mil/cb_prod.cfm?Product_ID=152&CATID=6<br><br>I have and use both the civillian and military models and would say that I prefer the military models even if they are more expensive. The extra tie downs hold ALICE compatible gear quite well.
