I/O Bio Merino Sizing Chart
5 out of 5
February 19, 2012
Of all the wool tops I own, the I/O Bio long sleeve crib is my favorite because it is the softest. It is quite thin and a little bit see-through, so I usually wear it as a base layer, unless I'm just sitting at home by myself. It's super lightweight and warm, and it rolls up very small when it comes to packing. I also appreciate that it doesn't look overly sporty (with neon stitching or the like), so I can wear it with normal work clothes, as well. I normally wear shirts in a size 6 (34B), and I bought the medium. It's form-fitting but not skin-tight, which I like.
Black, Carbon Melange and Coastal Green.
