  1. Had to have it


    from the minute i saw this I was sold, such a smart design. I was sick of using shoulder slings as inevitably one side of your body starts to hurt. I originally worried about the storage in the shifting pack, but it actually has a ton of space and can easily fit 4+ tacky collabs in there, plus all my tools tippets etc. The ability to also attach a rod to the side or middle part (if you dont take a net) is excellent. Well done simms.
  2. Great design


    I don't have this specific pack, but do have a Mindshift photography pack that this is based on. It has been fantastic the last few years. Easy access, good storage, smart design. With Simms' quality, this will only get better.
  3. Great pack


    Love the pack from the first moment. Really thought through. Only thing I have not figured out is how to put the tippets on the tippet holder on the right side of the pack
