I've worn POC's trail tee on every MTB ride in the past year and I can recommend it without hesitation. At 6 foot 5 I have a hard time finding cycling jerseys that fit me well. I wear baggy shorts as most of us do and wanted a looser fitting top to compliment the look. As I ride with a backpack on most rides, I do not need pockets on my jerseys.
The fit of the Trail T is exceptional, which is partially due to the elasticity of the fabric. On hot muggy VT days the shirt kept me surprisingly cool but I would imagine there are lighter jerseys out there that will do a better job of wicking sweat. With that said it dries quickly and stays odor free longer than other, more technical-looking jerseys I have had in the past.
You can't go wrong with the colors either. The blue is phenomenally vivid in real life and I'll probably purchase the orange at some point. Otherwise it's all black all the time for me. Pics forthcoming.
