Founded 2003 in Tokyo for the motorcycle community, Iron Heart makes the heaviest production denim on the market (21-25oz) with Bartack-reinforced copper rivets; a genuine buy-it-for-life jean at ~27 cents per wear over 15 years.
Strength
- Heaviest production denim in the modern market (21oz, 23oz, 25oz)
- Japanese selvedge on vintage shuttle looms, rope-dyed indigo, chain-stitched hem
- Copper rivets reinforced with Bartack stitching at every stress point
- Buy-it-for-life reputation — jeans enter their second decade with fabric still intact
Weakness
- Very long break-in — denim is so heavy it stands up on its own out of the box
- High price ($425-475 on the 25oz references)
