Athleta (from Athleta.com) focuses on inclusive, comfort-first sizing.

Key Fit Characteristics

Who benefits?

Fabric Differences That Affect Fit

Fit is deeply connected to fabric engineering:

Athleta Fabrics

• brushed-soft surfaces
• 20–30% spandex in many lines
• more stretch recovery
• thicker “hug but not squeeze” textures

Lululemon Fabrics

• Nulu → buttery soft, very stretchy
• Luxtreme → compression + performance
• Nulux → ultra-light, fast-dry

Lululemon fabrics tend to hold shape tighter, while Athleta fabrics feel more relaxed.

Key industry observations:
