“I was skeptical at first, but after two weeks of use, I am enjoying and appreciating the form and function of the Bommer 3.5" short! They are excellent in temperatures below 60 degrees (above that, and they feel hot). The exterior is durable and holds up in the rough terrain where I live. The pockets are also helpful for carrying treats for my four-legged running partner. Note, that I purchased a small, and the fit was perfect.”
