Adjustable Height - the Kiss, Kodiak Cub, Hybrid, Classic, and Denali all have adjustable lids due to the hook and bungee closure design. The height listed for each style has flexibility up to 3/4" if your optics are borderline too tall or if you run your binoculars with the eyecups extended, but this will make for a tighter fit.
Measuring Your Binoculars - prior to measuring the length, width, and depth of your binoculars be sure to adjust them to the position you use them to fit your eyes, including extending the eyecups if that is how you run them in the field.
Length - Distance from the eyecups of the binoculars to the objective lens end.
Width - Distance from the widest edge of each objective lens to the other, or any spot on the optic that is wider than the end of the objective lenses.
Depth - Thickness of the binoculars at the largest location. It is best to measure this by laying your binoculars on a smooth surface and measuring from the surface to the highest point.

Max Pocket Option - The Max pocket option is available on all models besides the Denali.  This is an extra pocket at the bottom of the pack, but it does not increase the main compartment size that will hold your binoculars.
