I work in a power plant, 7 days on/off rotating nights and days. My time is split between a control room and outside operator duties as a supervisor. I split 2 pair up between the 7 day/night period after which both pair are washed. I'm going to guess each pair of pants saw about 1,000-1,100 hours (2,000-2,000 total hours for both pair) of use and about 22-26 washings before first indications of failure at about 10 months on both pairs.
Bought 2 pair of these FRB13(11.75oz cotton denim) last March to replace 2 pair of FRB159 (8.5oz cotton canvas blend) after wearing those pairs out in the inner thigh/crotch after 11 months of use, expected these to last longer but they didn't. Worn and about to go in the same inner thigh/crotch area again after 10 months of use.
The rest of the pant is holding up very well, and my body shape may be to blame for where they are failing, but I expected better.
These were not too heavy for summers in Nevada and worked well with thermals in the winter.
The pants were very comfortable for their life, and the pockets work well for carrying phones, knives, tools, etc.
I will be upgrading to FRB229 and going a size larger, hopefully they last longer.
My working environment is tough. I've tried alot of work pants and these dungree's give me the versitility to take on what the day brings. Flexability with comfort even wnen I have to get into tight areas. Durable also, wash after wash...Finally a pair of pants that work as hard as I do!
They were suppose to be heavy. They were not. My return shipping label had no account number. I paid $17 plus to return. I tried calling a couple times only to be on hold for up to a half hour with no answer. Pretty sure I'm done with Carhartt.
