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.

My husband swears by these hoodies! Rain, snow and below zero temps he wears these. These are heavyweight and heavy duty.

Great and basic for spring

Size: Large, Color: True Navy

Feels more expensive than it is. The inside is soft enough and warm for a PNW spring and early winter. A heavy rain will eventually soak through but light to medium exposure, like walking the campus is plenty fine. Very basic and “normal” looking. Fit is true to size.
