The original performance underwear that rendered everything else obsolete.
"O" is for "original". The O-series boxer from Under Armour is the OG of performance underwear. Under Armour was first to the game with synthetic, wicking underwear, meant for the most extreme of sports. Super moisture transportation and quick-drying fabrics make these underwear ideal for day-in, day-out wear.
Under Armour has already compensated in the design of its apparel to be consistent with normal (S – XXXL) sizing. Please order the size you would wear in a non-performance T-shirt or pant. All numbers are in inches, except when noted otherwise.
S | M | L | XL | XXL | |
---|---|---|---|---|---|
Chest | 35 – 37 | 38 – 40 | 41 – 43 | 44 – 47 | 48 – 51 |
Waist | 27 – 29 | 30 – 32 | 33 – 35 | 36 – 39 | 40 – 44 |
Hip | 35 – 37 | 38 – 40 | 41 – 43 | 44 – 46 | 47 – 49 |
