Don't forget there are lots of different versions of X-pac. Different face fabric weights, different membrane thickness, different grid types, and with/without backing fabric. All with different prices.
Still relatively new to the whole myog way of life haha! I know of the vx21 but didn’t know of all the other variations that I’ve now looked up after reading your reply, great stuff!
Saw that aswell! Looks different to the other xpac I’ve seen, not sure where they’ve sourced it?
