We've taken Iron Heart's flagship product, the 634s straight leg selvedge jean, and given it the cold weather treatment.

We took their 21oz indigo selvedge denim and lined the entire jean with a heavy weight triple brushed black/gray flannel, but we didn't stop there. The jean is then completely coated in paraffin for repelling water. The jean has to be rinsed twice at the factory after the coating process so the entire thing is extremely comfortable and there is no break-in period whatsoever.

The warmest and driest pair of jeans you'll ever own.

We initially made these with cyclists and motorcyclists in mind, but once news of these leaked we had an overwhelming response from customers wanting to use them during snow sports. Whether you're just outside in colder weathers or actually tearing through roads on your motorcycle during the winter months, these will be the most versatile pair of jeans you'll ever own. There were only a total of 50 pairs of these made and they will not be restocked.

Notes: Due to the paraffin coating process these jeans are essentially rinsed and do NOT shrink at all when washed. These run one full size smaller than other IH jeans due to the shrinkage that occured during the coating process. With eventual normal wear and washing the water resistant nature of the jean will slowly go away, but will last quite a while with tests that we've done by washing the denim repeatedly. Best washed in cold water and line dried (as with all jeans).
