REI Garage offers the ExOfficio Men's Give-N-Go V T-Shirt in several colors (Charcoal pictured) for $11.73. (Amazon charges the same in white in select sizes with free shipping for Prime members.) Opt for in-store pickup to dodge the $5.99 shipping fee. That's tied with last month's mention and the lowest price we could find by $8. It's available in select sizes from S to L.
