This has some history. Was originally bought by Mike (@Filthy2123ozjunkie ). He lost some weight so we did an exchange with something I had in a smaller size.

Nice work @ Jercules. Mine have about a year of wear and 1 wash

They are very special to me. I am fortunate to have a few pairs from Mike. I got his 634 SR UHR and his PIH5dct the 25oz double indigo with the turquoise arcs. We had become really good friends. The Iron Heart forum brought us together. One of the reasons that this place is so special to me.

Here is mine, owned it since 2001

Here is my pair similar fades in the back pocket. Mine is the older v2 version but same fabric.

Lol this year. I just realized its 2026 the IH meeting so I will be good to go. I go to Greece every year. I am from Greece originally but have been living in the US since 1988

All an little ethical company really owes to their customers is transparency and good customer service which Iron Heart provides 10 fold. Loyalty should never be associated with money. If it does, the only think you are saying is,that the only thing you value is money.

All feel different and have very different Characteristics. The 16oz slb is the most breathable. The 19 is a left hand twill and unsanforized. Its stiffer and more rigit with great fade pottential. The 14 oz is a nice all year weight. Then you have the 25oz heavy but softens up beautifully with wear and fades very nicely. You have the 18 with vintage fades, the 17oz with natural indigo. They all feel different, fade different so at the end of the day it is a matter of preference and variety.

My daily tool watch.

@Matt yes is came in a straigh cut also and it appears closer to a 666. Kinda like a slim straight.

Thank you @Giles

@Jett129. Thanks!. I am not familiar with the 501's.There is a sample tag 40 on this thread and looking at the measurements the closest I can come to is the 777. I am obviously trying to see that IH cut that are they based on.

Question: is this cut closer to a 777 than any other cut?

He just like lose jeans. Its preference. If what you wearing feels good to you who gives a feck what everybody else thinks. There is no way you are wearing 25oz denim and its too tight and somehow you are not aware of it.

@hugothecowboy. It applies for the most part only to the models that are not pre washed at the factory. In the current lineup I think all 25oz and UHR need a soak before wearing. The 21oz, 19oz, 16oz and 14oz are all pretty washed. The 19L is unsanforized but washed.

Yes if you go to Iron Heart Japan you will see them. They have the 634s and the 634bk.
About 10 years ago or so IHUK had a 666s- bk that will fade to gray but I never remember seeing a 634bk

@hagerman8. Its possible that is a Japan only product. Obviously I am not sure but somebody will chime in

@michael.rose0107. Anytime my man!

If you want Ib sizing up on 634 maybe your play. The 25oz is will also feel structured. Its heavier and stiffer than the 21oz. The 888 will taper pretty meaningfully from mid thigh to knee so it will feel tighter from about 3 inches down the crotch to knee than the 634.
