Randall H.wrote a review of Icebreaker BodyFit 200 Oasis Crewe - Long-Sleeve - Men's on January 24, 2012
I love icebreaker and for a botom layer his one can't be beat! I wear this shirt day and night and everything in between! ( dont worry I have another one to rotate in).
Sizing does seem to run small on this particular item as I ordered an xl to make sure -as they can shrink a tad over the years -and it fits me pretty snugly -more like what I feel a large would do. I'm 5'8" 175 and pretty sturdy /in shape but wouldnt usually buy xl for a base layer.
