Some of the swim brief reviews on swimoutlet get quite detailed and graphic
Several guys mention that the first thing they did was cut out the liner. Reading all the reviews gives a good idea of what is going on with guys when they pick a swim brief out and try on a specific brand, style, color and size for the first time
It appears that a lot of guys on HS and college swim teams are buying the inexpensive Sporti and iSwim briefs for practice wear, switching to a more expensive brand like Speedo or Tyr but only for the big meets.
And many guys have gotten hooked on the gather skimpy Sporti Euro brief as their go to swimwear for practice.
Sporti is selling black and navy spliced briefs with a contrasting splice color of red, yellow, gold, green, royal, red or purple. High schools often have one of these latter colors as one of their school colors, the idea being that HS swim teams will want a basic black or navy brief with the school color in the splice.
