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.

Great for men who work outside!

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.
