Great! What color are you looking at? I really wanted the "anaconda" (forest) green, but it never seemed to be in. So I got "foliage" instead. It will be my new BOB, so the old one can stay permanently packed and ready for DMAT deployments
If you are tall like me (6'3"), you will need to really let the shoulder straps out to get the belt to hip level for proper load transfer to your pelvis with heavier loads. The pack bag ends up riding lower than a typical day pack, but it really works. Fortunately, the shoulder straps adjust from both top and bottom ends, so you can place the padding just where you need it. The stays can be adjusted by bending, if needed, and there are adjusting straps on the belt to cinch the load in tight.
I'm pretty sure you will find it makes a fine SAR pack, if that's what you intend.
