Athletic Works ButterCore Tee vs Athletic Works ButterCore Long Sleeve Tee

These are the same ButterCore tee in two sleeve lengths, so the fabric, relaxed fit and size range (XS-4X) are identical. The short-sleeve version suits warm rooms, lounging and low-impact workouts; the long-sleeve version adds coverage for cooler days and layering. Owners of ButterCore pieces consistently praise the soft, stretchy feel and moisture wicking, and the main complaints are thin fabric and light colors showing wear. Pick by climate and coverage, not by quality.

• Choose the short-sleeve ButterCore tee if you want a cool, breathable layer for lounging, warm weather or low-impact workouts.
• Choose the long-sleeve ButterCore tee if you want the same soft fabric with arm coverage for cooler days, layering or sleeping.
