I have memorized the model number of 4693 - a bra built for human females. The wide straps are awesome... they are tapered in such a way that they don't look like industrial strength suspenders, but they stay in place and don't flip over or cut grooves into your shoulders.
These bras do not have underwires - which means they don't get mangled in the washing machine or poke through. I have been buying this model number for almost 10 years now. Each bra has lasted me for almost 5 years with weekly washings in the washing machine and clothes dryer.
During their productive life span, they do not falter in support or comfort. I've never had a problem with hooks or eyes coming off the fasteners, or loose threads coming off after a wash.
Like any elastic garment, however, it will not last forever when you wash and dry all the time. Some people hand wash their bras and line dry them - I'm sure they would last much longer if I did this - but I just don't make the time to go through that effort.
The straps have a tiny amount of tapered padding that also helps in the comfort arena. When they call this an 18-hour bra, they are not kidding. I have had a number of situations at work where I have had to stay late - sometimes stay at work for a 24-hour shift now and then. When I've had to do this in the past w/ other bras, I thought I was going to drop dead from the fatigue and neck aches - but even after 20+ hours with this Playtex 4693 18hr bra, I am barely aware that it's even there - because it does it's job without needing constant fiddling and re-adjusting.
I don't even try on other bras anymore - this is THE best bra there is for comfort and support.
