Our relaxed tapered cut jeans, constructed from 21oz overdyed indigo selvedge denim. To create this darkened variation, we take a pair of standard IH-888S-21 jeans and steep the entire garment in black dye using a direct dyeing process. This stains the indigo denim and stitching, with the added bonus of removing all shrinkage from the fabric. A unique middle ground between our traditional indigo and black denims, over time the fabric will gradually fade with blue-tinged hues in high-wear areas.
Please note that previous versions of these jeans were overdyed using sulphur dye. Due to the environmental impact of sulphur dyes, we have decided to switch to a direct dyeing process when overdyeing our heavyweight denims. The only noticeable difference is that this new process does not oxidise the brass hardware as previously. You can still expect these jeans to age and fade similarly to older models.
Our Fit Notes
The 888 has a higher rise with more room in the top block, tapering gradually from the knee to the hem. This creates a balanced silhouette that feels comfortable in the seat and thigh while still offering a cleaner leg opening.
Who This Is For
A good choice for those who want comfort in the top block with a more refined, tapered shape below the knee.

Sanforized, One-Washed & Overdyed
- Sanforization is a post-weave mechanical process which removes most potential shrinkage from a fabric before garment construction
- To further reduce the risk of shrinkage, we wash the completed garment in an aggressive industrial washing machine.
- Following this, a high-temperature overdyeing process removes any remaining potential shrinkage
- This garment may fit slightly smaller than its non-overdyed counterpart. Please refer to our measurement charts carefully
- No further shrinkage is expected if washed in accordance with our guidelines
Stretch Details
- The waist will stretch out approximately 1" with wear. All other dimensions that are put under pressure will stretch proportionally to the waist
