Version 2.0 of the Support Belt allows you to choose from ANY Milliskin color, and has more comfortable branded elastic!
The Support Belt gives support and don't show underwear lines under tights.  
I took inspiration from support jocks, dance belts, tech fabrics and my own experience when designing this utility garment.  
The Support Belt was designed specifically for men to wear under tights, leggings or cosplay costumes.  It gives support for all activities and full range of motion.  It virtually disappears within the natural contours of your body.  You don't have to announce your thong to the world, you won't be made fun of for wearing boxers, and you don't have to worry about the line of your briefs or jock.
