Great for backpacking
I took a pair of these ExOfficio Give-N-Go shirts backpacking for three weeks across China, Thailand and Cambodia in the summertime. They are perfect for travelling light. They barely weigh anything, can be rolled up tightly. Easy to wash by hand and they dry quickly. I am 5'10, 160 lbs, and wear a 40R jacket, and the mediums fit perfectly. In the hot and humid weather, these keep you cool and dry. I only took two with me and washed them at night before I went to sleep and put the same shirt on the next day.
As usual, Ex-Officio products continue to deliver.
