Iron Mordant Foxfibre® Tsuriami Crewneck T-Shirt - Coyote 70

We’re thrilled to introduce the Iron Mordant - a natural next step as Wonder Looper continues to expand and refine its craft. This version features the extraordinary Foxfibre®, the only long-staple cotton organically grown here in the U.S., dyed with earth-derived hues. Sally Fox’s innovation is nothing short of groundbreaking - she’s created a fabric that’s truly one-of-a-kind, and it simply doesn’t exist elsewhere. For Iron Mordant, Wonder Looper chose the standout shade Coyote 70, a rich, naturally beautiful brown that looks and feels effortlessly elevated. Already, demand for these tees has been impressive, so that sentiment might just be universal.

Lightweight yet impactful, this crew neck clocks in at 228 gsm, a noticeable step down from its hefty predecessor - making it an ideal piece for year-round wear. But make no mistake: it still embodies that unmistakable Wonder Looper hand feel - soft, plush interior balanced by a pleasantly textured exterior. Woven on the brand’s beloved century-old Tsuriami loom, this tee develops a uniquely lived-in character after its first wash - a soft, airy interior juxtaposed with that delightfully rugged finish outside.

Fit Notes: Shop owner Tommy is wearing a size large this round. This is considered an athletic fit, which reads to us as a roomier, more American cut. It's not often we see Japanese brands with that sort of cut, but the Wonder Looper owners built this brand with specifically that in mind. He honestly prefers the large to the medium. Ultimately, these are easier to get on and off than the heavyweight, so if you like a more fitted look, you can go with your true size. Tommy would likely still size up to a size L if purchasing this piece. He is our standard fit model at 5'10," 161lbs with a 40" chest.
