Cut and sewn in California
Seeing is believing. These photos confirm our theory: the Japan Red Fire is one of those denims that sounds incredible in theory and looks even cooler in reality. An indigo warp and brilliant, fiery red weft make this limited run selvedge from Japan stand apart from anything else in your denim collection.
Note: We recommend going up one size in this fabric.
Gustin jeans made from sanforized raw selvedge denim from one of the finest mills in Japan. This one makes use of a unique weft to spectacular result. It starts out nicely with a deep navy warp, creating a dark top surface. The weft takes things in a totally new direction. Its fiery red poly yarn is woven into the weft yarn, and this changes the entire character of the fabric. Obviously, if you cuff this denim, you'll see a bright flash of red, but what we enjoy more is how the red weft makes its presence known by showing through the top surface of the fabric. It gives the entire fabric surface a subtle red tint and shadow. If you're ready for indigo denim like no other, act fast, as this is a limited run.

"Measured myself as instructed, but missed the "order one size up" instruction as these have a red poly weft thread and I should have ordered a slim 35" waist. They were snug out of the package (kudos on minimal packaging), and tight after washing and letting hang dry. Washed them twice now, but pulled them from the dryer after 10 minutes and wore them damp. They've stretched perfectly, and I love the fit and unique color. So now I've ordered three more pairs of jeans from stock, and will be ordering more on campaign."
-Leslie F. | Verified Buyer
"These are gorgeous and other worldly. They have a slight shimmer that makes them look like a very sapphire blue. Very bold and striking, but unique. Highly recommended.
May not stretch as much since the (horizontal) red weft is poly and doesn't stretch like cotton. Consider sizing up.
I usually get 33 slim from Gustin, but I got these in 33 straight, and they're snug through the thigh after 5 wears, and I think it's quite flattering."
-Ash M. | Verified Buyer
"I like the fabric a lot. Important to note when ordering a Gustin: their sizing is NOT like other manufacturers -- I had to go up TWO waist sizes to eventually get a pair that fit. I'm a 29 in all other jeans; needed a 31 for Gustin."
-David K. | Verified Buyer
"Stunning in person, particularly in sunlight where the red seems to glow through the denim. They fit perfectly when following the sizing guide and arrived without any issues."
