My son is on a mission in Chile and these pacific shirts are his favorite! He wears the Atlantic long sleeve also. But he absolutely loves the Pacific short sleeve shirts. He has never complained one day in having to wear these all day every day. He has the slim size shirt and would tell anyone to buy them. It is humid and very warm where he is at and he said how comfortable and cooling the shirts are. We didn’t buy him any other type of shirts. He has all of these Pacific and Atlantic shirts. He got small pen marks on a few of them from a broken pen in the dryer and the pen marks started fading over the next few washes. They have been great stain resistant shirts. He eats in these shirts and no stains remain, they wash away. He also loves the ties from AndCollar. If you are hesitant to spend the money, they are worth every penny!
