I own two of these shirts (grey and coral) and have gifted a few as well. This is my favourite running top. I'm not normally a fan of crew necks but I find this one doesn't go up too high on the neck (like one of those cheap tshirts) so it's very flattering. It is made with silverescent technology that is the best for sweating. It prevents odour-creating bacteria from settling on and in the fabric so it never smells (unlike other workout wear that eventually needs to be thrown out because it gets too stinky). My favourite thing about this shirt is that it wicks sweat away from you so you always always feel dry, even during the most intense workouts (and also dries quickly which is great for travelling). It's light weight but acts as a great barrier to the wind, and has thumb holes to keep your hands warm. I have already decided my next lululemon purchase will be one of these shirts in the short sleeve style.
