guide

Our kit runs a slim, true-to-size fit. Between two sizes? Size up for a relaxed look. Numbers below are body measurements — real garment-flat charts drop in once we’ve measured stock.

How each piece fits

Pick by the cut

  • Tracksuit — Slim, athletic fit. Cut close to flatter a trained frame and tapered to the ankle. True to size; size up if you’d like a roomier feel.
  • Short & t-shirt set — Regular athletic fit. True to size.
  • Core T-shirt — Relaxed fit, wider neck. True to size.
  • Performance T-shirt — Athletic fit, closer through the chest and arms. Size up for more room.
  • Vest — Fitted. Size up for a looser feel.
  • Hat — One size, adjustable.
