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!

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.
