Royal Robbins Ketchum Long Sleeve
Here's what other sites are saying:
Sometime a ?secret weapon? can hide in plain sight. The Men's Ketchum Long Sleeve Trek/Travel Shirt from Royal Robbins (which is code for long sleeve), has so many amazing features built in you wouldnt be believed if you escaped with it and shared the 411! But if you did and were running about in the wilderness, or, say, across the Brooklyn Bridge in the dead of winter at midnight, youd be AOK all the way.
