I own 2 of these, 1 stoic 150 crew, and 1 stoic 150 zip neck (same as this without the side pocket). This is a more true to size fit than skin tight fit (I wear a M in most things and this, but a L in icebreaker bodyfit). I love the zip necks for the temperature regulation, so wear them more often than the crew neck shirt. The weight is great for runs, biking, workouts,lifting weights, etc. My favorite workout shirt (my old polypros are in the back of the gear closet now) because after I let them dry from all the sweat, they are good to go for a few more workouts! Also, when biking into work, they would be dry by the time I would change back to go home and not be stinky! The 150 weight is nice and light, 200 is heavier and not as high aerobic activity friendly unless it is pretty cold out.
The black/boysenberry color combo is stunning. I'd buy another one if a cool color combo came out, but I just can't justify more unless one falls apart :) So far, they have all held up over the past 9 months with regular washing and air drying, no snags, holes, or seams coming undone.
