Some say these bestsellers are softer than morning mist rolling off the Three Sisters. Grayer says their jaspé weave and rich color depth make these 8.7 0z, 3-ply heather flannels a mid-season must have for any serious wardrobe. Jas-huh? Jaspé is a mottled weave of yarns, each of which is twisted from separate colors to create beautiful heathered highs and lows that run through a garment to give it texture. The way salt and pepper keep your steak from falling flat? Jaspé does that for your shirts.
