Summary

Lululemon Scuba Oversized Full-Zip is intentionally oversized with dual letter sizes (XS/S, M/L, XL/XXL). Many shoppers who wear a numeric 6–8 find M/L huge and prefer XS/S. Treat ‘oversized’ as the cut — size toward the smaller dual band if between. Not the same sizing as classic Scuba or Align.
