17oz Selvedge Denim Slim Straight Cut Jeans IH-666N - Natural Indigo

The Iron Heart IH-666N Natural Indigo in 17oz Japanese selvedge denim is available at Rugged Gentlemen Shoppe with fast local shipping and easy returns. Due to limited production, certain sizes can be hard to find once they sell through. If your size is currently available, it may be worth securing it while stock lasts.

Our medium rise straight slim cut, constructed from 17oz natural indigo/organic cotton selvedge denim. Initially, this denim will be very reluctant to give up its indigo and takes a long time to start fading. However, once fade patterns do start to develop, they will do so with lots of contrast.

Our Fabric Notes

This 17oz natural indigo denim offers a substantial feel with a slightly different tone and aging character compared to standard rope-dyed indigo. The fabric balances durability with a more nuanced color evolution as it wears in.

Our Fit Notes

The 666 is one of Iron Heart’s more streamlined straight cuts, with a lower rise and a slimmer fit through the thigh and knee compared to classic models. It offers a clean, contemporary profile while still retaining a straight-leg look rather than a true taper.

Who This Is For

Well-suited for those who prefer a slimmer silhouette and are comfortable with a closer fit through the leg. A good option for those who want something slightly different from classic indigo while still retaining a mid-to-heavyweight denim feel.
