Tanga offers 5 Pairs of Men's Moisture-Wicking Mesh Shorts for $29.99 with free shipping. At $6 per pair, that's tied with our mention from two weeks ago and a very low price for moisture-wicking shorts in general. (We've seen most stores charging at least $8 for a single pair of comparable shorts.) They're available in select sizes from S to XXL.
Note: These ship in random colors.
