Very nice & heavy sweater.
Size: X-Large, Color: Grey
Very nice and heavy sweater. Im 220lbs and ordered an X-tra large, which is very snug/tight as this is form fitting. Depending on your build, if youre around 220LB with a little bit of stomach maybe order up to get a better fit.

Superb hoodie for mechanics
Size: Large, Color: Dark Green
The #1 favorite hoodie of mechanics. Nice and thick which makes it very warm and durable, and a great fit. My mechanic son gets one of these every year for his birthday, and never wants any other brand.

Love them!
Size: Large, Color: Dark Green
Love these heavy weight hoodies! I work as a mechanic and put these through a lot. They run true to size in my opinion. Very warm and durable as well! They do shrink after several wash and dry cycles so I would advise either hang drying and not drying with a machine or maybe consider one size larger if you are on the fence.

Great quality
Size: 3X-Large, Color: Graphite Heather
The hoodie is thicker and good for cooler weather. The sides stretch making it very comfortable. I have one from 8 years ago and it has held up very well taking through all types of extreme terrains and conditions. I’m glad they remained the same quality for a good price.
