The P.I. sugar shorts have a 4 inch seam & the attack shorts have a 5 inch seam. The sugar shorts are 6 panels & don't look like the padding is all that great, but the attack shorts are 8 panels & more substantial. The best part - TE has the attack shorts on sale @ 20% off! The bad part -they only have L and XL left. If L or XL is your size - they are a great deal.
