Hand felted from a responsibly sourced New Zealand Merino Wool blend, our men's house slipper in Heather is not your average boiled wool slipper. The heather color uses no dyes giving you the comfort of knowing your slippers are all natural. With unfussy styling and minimalist appeal, this slipper was designed with the modern man in mind. Wool insulates, breathes and wicks away moisture while naturally preventing odors from setting in. See Fit Guide below.
