I've used about every type of Bino harness on the market and the Marsupial enclosed is top notch. I've been using the Large model for my Swarovski 15x56 SLC for the last 3 years and it keeps my optic protected well from the elements along with allowing quick and simple access. The accessory pockets are equally awesome and accessible. The harness portion is comfortable and features robust buckles. I'm able to store all my necessities in the pockets. I keep extra rangefinder batteries, d-loop cord, a mini Bic lighter, and more in the front zippered kangaroo pouch. In the back mesh pocket I usually keep my tags, and sometimes a handgun. I highly recommend this product!
