Ok, I've had some time with it. The Tahr is a great pack bag, if your looking for a bag to stretch from day use to around 5 days. This of course is a no frills pack, and that is what I love about it. No need for a lid, no organization (we put everything in stuff sacks after all) very light weight for how robust it is, straight purpose built. With the ability to add and subtract pockets, this may supplant my MW.
I'm not sure how much I will use the meat shelf, but I can see how useful it is when needed. I think the meat shelf will work great for the first load, then empty your bag and haul the rest inside.
Not much else to say, it is simple. The comfort is all in the frame and this is a bag attached to the frame. If your looking for a daypack size, that has some extended trip tendencies, with the ability to grow with pockets, then give this pack a good long look.
