Like most pouches from other manufacturers - you'd think it would take a bit of effort to mold the pouch to fit the saw or it would be a little too small or a little too big. I can tell you that it is a PERFECT fit for the Silky Big Boy. It is extremely well make and is low profile enough to strap it to the side of my pack and still be out of the way. Like every other product I've had from CenterLine - it's just perfect. You could always find a cheaper ouch but when it dies you'll be back here to buy the best once and have it for life.
