A first for Iron Heart, a slubby heavy flannel (SHF) shirt.  Constructed from a 12oz slub yarn cotton with a herringbone weave, the result is a more pronounced texture and uneven hand than our ultra heavy flannels (UHF).  Whilst the face of the fabric may appear slightly more rugged, we still double brush the reverse to create a very soft, comfortable flannel.  Substantial, warm and windproof  - seen here in a work shirt cut with grey slubby check.
