According to Mountainsmith's own web site the strapettes are designed to be used on Day, Tour, Tour FX, Ether 20L and Travel Trunk packs. That said, I notice the Blaze has the same type buckle connections for the shoulder strap that are are needed to attach the top straps of the Strapettes. What I don't see is the buckle or strap needed to connect the other straps. I think the question would be best put to the people at Mountainsmith. They have always been helpful and courteous when I've spoken to them. They are also on Facebook so I'm sure the answer is out there.

It is not listed as compatible with the Blaze. This handy shoulder harness converts the Day, Tour, Tour FX, Ether 20L and Travel Trunks (L-XXL) into shoulder carry packs.
