This looks like it only carries a board...
This looks like it only carries a board horizonaly. How are the vertical carry straps set up?
Where it shows the four buckles in the picture, the left side has male buckles, and the right side has female straps. The four buckles are unclipped from the configuration shown, and they are clipped together to carry the board. Does that make sense?
That's correct, they un-clip and then re-clip across each other to hold the board directly on the outside back of the pack vertically! YEAH lyric, I understood, but that's a hard one to explain!
p.s. By far the sickest hiking and sledding pack... I even use my as a daily backpack.
