prAna Flow Shirt - Short-Sleeve - Men's - 2007 BCS

Great climbing shirt for all sorts of climbing. Works well with a silk layer underneath if it is chilly, take it off when it gets warmer. Wash inside out to prevent pilling. Mine starting pilling after 2 years (I started washing it correctly after the 2 years), so probably not a huge deal.

This shirt breathes like it isn't there. It goes out of its way to stay out of your way whether you're bouldering or strapped into a harness. Even on the warmest days or in the stuffiest of gyms this shirt stays dry and wont cling like normal t-shirts do. A must-buy for any athlete.

I go a couple of these -- i use them to run in when it is moderately cool out and i really like them.

This shirt is an excellent addition to my collection of breathable shirts. I use this shirt primarly when climbing mountains in the Adirondacks. Its a great shirt for a good price. It keeps me dry and comfortable.

This shirt goes out of its way to stay out of your way. It feels like it's not even there, it's so comfortable and lightweight. When your workouts leave you drenched in sweat it doesn't cling to your body like a regular t-shirt would, leaving you as unhindered on your last bouldering problem as it did on your first. While it's ultra-breathable, keeping you comfortable in even the stuffiest of gyms, it's also not pierced by the breeze, allowing you to jog home from the gym in it or climb outdoors even on cool October days. A must-buy for any athlete!
