I don't think so - its weak, improperly welted, made of thin soft leather.
I have replaced all of my GB masks - every one has failed in use
Amongst my favourites is this system

This allows an axe to be carried in many ways - on a couple of trigger clips on the belt, on the pack

or on a baldric (my preferred method of axe carry without a pack)

Note that the carry method is poll first - allowing safe withdrawl without cutting off your fingers!
The same fit works on Wetterlings, Rosselli and GB

I even had to replace the masks on my working axe

It needs a very short axe (shorter than the SFA) to benefit from belt loops and stop you walking lopsided

With a very small axe you can get away with a single trigger hook

You can even carry an axe across your back with the system topknot devised

I claim no kudos for the execution of the leatherwork - that belongs to singteck (most), Dougster (working axe) and topknot (back carry system for the viking axe)
In any event, as you can see - there are many types of mask and carry, but, for me, the GB mask is simply a poor design, poorly pur together of inferior materials.
