“I didn't have any hi-vis cycling clothes so I decided to get this in lava to go with my alt road bibs. I love ls tee! I wear it mountain biking too. I sweat a lot and so far it is super breathable and hasn't retained any odor. According to the size chart I'm a small but I like my tops on the looser end and ordered a medium. It is exactly how I like it, though I could have probably gone with a small. My only worry is that I won't be able to get the mud stains out that I acquired on the very wet gravel of Denali National Park last weekend.”
