Excellent quality product, this is the norm for ALPS OutdoorZ! I use this with my chase kit which is also a new purchase. I have an older (5+ year old) Big Bear. The buckles have since been updated so the new items no longer fit the old ones. No problem, I contacted ALPS and they sent me new buckles for a fee that I attached to an old backpack. The Bino case is therefore suitable for both cases. On the other hand, as others have said. It's a small thing! An extra half inch in length and height, or a wing about an inch longer, solves this one disadvantage. For reference I use the Vortex Crossfire 10x42 binoculars. The fit is good in every way EXCEPT the valve can be secured.
