I purchased an Imago bag with the Absolute strap last weekend and I just wanted to say......if you are wondering if the strap is worth the extra money, it is well worth every cent!
I get neck and shoulder problems if my bag is too heavy - not that that stops me from carrying too much when doing errands! I loaded my new bag up to its volume capacity with books, then walked about a block to the library, wearing the bag across my body. I barely knew that I was carrying all that weight. The strap is like have a little pneumatic suspension system on the bag!
Thanks Tom Bihn crew - the bag is perfect and the strap is a miracle!
