Split Short 3" — Split-hem running short with a bonded, seam-free inner gusset.

Split Short 3"

4 / 5 from 1 review read them

A 3-inch split short cut for stride clearance. The inner brief is bonded rather than stitched through the gusset, so the only seams left on the inseam sit on the outer thigh where they are not loaded during a running gait. Rear zip pocket holds a key and a card.

What this piece does not do

  • We publish where the reflective trim is and what it is made of. Whether you are seen depends on lighting, angle, weather and the other party, so we make no visibility or safety claim.
  • No antibacterial, antimicrobial or anti-odour treatment is applied to this piece, and we make no claim of that kind. It is a knit that can be machine washed.
  • It will not make you faster, stronger or fitter. It is clothing. What we do and do not claim.

4.0

The gusset is the difference

Nine miles and no rubbing on the inside of the leg, which has not been true for me in a 3-inch short before. Marking down one star because the rear pocket is tight with a large phone case.
