The demo gloves are the best work gloves I've ever bought.. I used to buy the "Industrial" mechanix gloves for $32/pr at lowes.. I'd be lucky if they lasted a month before the seems split ON EVERY PAIR I EVER BOUGHT.
made it 9 months on my first pair of demos before I lost them at work, and not one rip or split seem yet.. I'm on my second pair for work, and they have been exactly the same so far.. they will EVENTUALLY have some holes worn in them, but all the parts that take abuse have two layers or material and the stitching hasn't broke on any of mine..
These are my 9 month old gloves a few days before I lost them.. lol
Edit - I just happen to have these next to me.. these are the Mechanix Impact Pro's.. their most expensive model sold at lowes - and this is what you can expect from them. The index finger, thumb, and "crotch" between them are all ripped open from the stitching failing.. this ihas happened to every pair I've ever bought, and I've gone through a lot.. you can see they are not nearly as worn..
I wear a large in both models.. the Milwaukee largess stated out just slightly big on me, but they actually shrunk a little and are a perfect fit after they get worn in (if that makes any sense)
