SIZE GUIDE — CORE ORGANIC REGULAR TEE


This CORE tee is a regular unisex fit crafted from organic ring-spun cotton. European sizing runs smaller — US movers should size up once for a standard fit.

Fit Philosophy

  • Regular unisex cut: straight body, balanced chest width.
  • Movement-led: enough ease for breath, rotation and upper-body pathways.
  • Medium-weight organic cotton: stable, soft, reliable for practice.
  • Details: clean neckline, structured sleeves, natural drape.

How to Choose Your Size

1 — Choose your vibe:

  • Balanced, everyday fit → choose your usual size.
  • Looser / more space for drills → size up.
  • Closer, form-following fit → size down if between sizes.

European sizing runs smaller for US movers — US customers should size up once. When in doubt, compare the chest width with a tee you already own.

  1. Lay your tee flat on a table.
  2. Body length: top of shoulder to bottom hem.
  3. Chest width: armpit to armpit ×2.
  4. Sleeve length: shoulder seam to cuff.

Option 2 — Measure your body

  1. Use a soft measuring tape.
  2. Chest: fullest area, tape parallel to the floor.
  3. Desired length: from shoulder down to preferred hem.
