These are great tops, I have a lot of icebreaker, ibex and smartwool. I am new to Woolx. So far my experience is great, I love the athletic fit, skims your body but isn't too tight/revealing. I think they are true to size (both size chart and my "normal" size). I have broad shoulders/long arms and honestly wouldn't mind a bit more length in the sleeves (I'm inclined to believe the models are much more on the average/petite side). But the sleeves are definitely not too short and I think for most people will be generous in length. The fabric is nice and color is as advertised. The Mocha is a beautiful neutral. I've always purchased 100% wool prior, but the blend was pleasantly surprising. When the funds are available I will definitely be getting more and trying different styles.
