I'm not sure that I had many expectations for a leash other than to keep my pup nearby, but the thoughtful design of the Flat Out leash has amazed me.
I'll start at my hand and work to my dog's collar, pointing out notable features:
The webbing is light, but strong and looks great after its fair share of abuse on muddy hikes. The padded hand loop isn't bulky but provides some comfort that is much appreciated on long trips. The hand loop is adjustable for use as a waist leash (something I've yet to do), but also unclasps completely to quickly wrap around a tree, post, or that railing outside the local coffee shop. I was a little skeptical of the loop staying secure, but after seeing the design and using it, I feel confident that the loop will only come undone when I want it to. Near the dog-end, the traffic loop allows me to keep my pup nearby when we're waiting to cross the street or passing a less-than-friendly dog on the trail. Finally, the clasp quickly and easily attaches and detaches from a collar or harness (not that my dog has a problem patiently sitting, but...OK, we're both incredibly impatient). Even when the collar loop is hidden from sight by fur, I find it's easy to get the leash securely fastened.
There have been a few times when a leash of a different length (longer or shorter) may have been ideal, but I find that this is a good all-around length. Many parks actually require a leash that is 6' or shorter, so this fits the bill quite well. Friends and dog sitters who have used the leash have commented on how great it was, and despite my apprehension to get too excited about a dog leash, I must agree.
