I've never had any type of enclosed system before so this was a night and day difference from just a regular bino harness. I spent the first week of the year on a hunt and it worked flawlessly for me. The only struggle that I had was keeping/getting the lower straps set in a range to adjust from me wearing light layers to heavy layers, but that was a personal issue and not a product issue.
The added features to the 2.0 make the best harness on the market even better. I absolutely love this thing!
