Midweight interlock. It's thicker, soft, luxurious, and warmer. You won't wear it above about 70-degrees, but it's the best choice when it's cooler and you don't necessarily want to layer over it.
Thermo Fleece, 100% pure Australian Merino wool, interlock knit, 18.5 microns, 200 gsm.
FIT: On the snug side. They stretch a lot, but if you wear a large T-shirt or dress shirt and you want one of these to cut you a little slack, buy up a size. Machine washable and dryable, but we always suggest air-drying.
I/Grant wear a large T-shirt and go for XL or even 2X in these. But I like real loose clothes. Order this in your normal t-shirt size and this'll fit fine.
NOTE: these crew-neck, Dark Navy tops are one time time deal. Can't get more once we're out.
