I recently bought three more of the yellow Echo Tee shirts. I'm fortunate enough to ride my bike to work year round and I really don't want to get hit by a car. The yellow shirt is bright!...can't miss it! Sure it's not one of those body tight bike jersey shirts, but I'm not racing....I'm commuting. The Echo breaths extremely well. I actaully don't sweat in it...it breaths that well. I'm sure this shirt would be great for hiking and even travel. It's super light and can crunch up into the palm of your hand.
