One thing I forgot to mention: Be prepared to have several panic attacks at the base of your tree thinking you forgot your saddle. The Mantis is so light and wears so well, you will literally forget you have it on after about 30 seconds. During the prototyping phase I actually did this a few times at the house. I wore it around the house for about 4 hours after a test hang, not on purpose, until my 7 year old daughter asked what I was doing wearing a funny diaper. My closest call to public embarrassment though was when I actually wore it to the gas station to get lawn mower gas. Just saying, you're going to "lose" your Mantis several times before you realize you've been wearing it the whole time you were looking for it.
