This is a pretty nice tool roll. I think "Legacy" means the color, the material is synthetic. Speced at 26 x 13 inches, I just measured one of mine at about 610 x 350 mm. Made somewhere in Asia IIRC.
These are not as sturdy as the Knipex rolls but bigger and still good quality. Some of the reviews comment that the pockets are designed wrong, because if you put small items in the small pockets they are on the "outside" of the roll and could fall out. I could see that if you didn't do it up tight.
They hold quite a lot, I have one that took two full sets of long handled SAE and metric combination spanners and a handful of ratchet spanners. And another for pliers and cutters.
Not expired or sold out, don't know why someone reported it as such. 4% claimed as of my comment.
