Does this have 3 pockets on the back? If not which colored ones do?
Yes, this jersey does have 3 separate back pockets. If you enlarge the photos you can see there are seams separating them. Also, even in the description it states as having 3 pockets. Sometimes, too, you can get better or different pics. on Competitivecyclist.com (which is a 'sister' to backcountry.com.
And, don't forget, if you don't like something (fit, etc.) you can always return it. Backcountry is great about returns!
Hope this helps.
