- Familiarity: I've put it through the wringer
For travel and unpredictable conditions, the long sleeved Polarized T-Shirt is a go to. It is heavy enough for cool days in the sun, but light enough for the warmer days. I would for sure recommend sizing up if you are in between sizes. The fit is slim. I wear a Large in this, but usually a Medium in other Patagonia shirts. Check the sizing chart, as its measurements are accurate for this shirt.
