Because the ring doesn’t create a complete costume. As a Green Lantern, you wield a ring capable of forming solid-light constructs with the slightest application of willpower, including your very stylish costume. Unfortunately, the ring is incapable of manifesting underwear, so the Guardians of the Universe hand out a pair of  Green Lantern Symbol Men’s Underwear Fashion Briefs to each and every new recruit.

• Our high-fashion, EXCLUSIVE Green Lantern briefs for men are a pair of soft, breathable, stretchy and comfortable underwear that offers full support and additional comfort while wrangling unseemly space criminals vandalizing the living moons of Space Sector 2814.
• Wide and green elastic waistband adorned with black and embroidered Green Lantern symbols.
• A front and center, screen-printed Green Lantern symbol.
• Bright green borders and a black and green color scheme.
