    I picked this up hoping it would help me keep cool last summer. It did an okay job, but I must have had my expectations too high. I wore it a few times, but turned to my merino wool time and time again over these undershorts. At times it seemed as though I was wearing plastic bag for all they breathed. Good in concept. Not so good in execution.
