What to Consider

Materials & Construction

·Merino — Finer than standard wool with exceptional breathability. Naturally resists odor so you can wear it longer between washes — ideal for travel and everyday basics.
·Cashmere — Softer and lighter than wool but more delicate. Quality cashmere (look for long-fiber, 2-ply) pills less and can last a decade with care.
·Made by Calze GM Sport in Italy.

Longevity & Care

·Merino — Most merino is machine washable on gentle cycle. Lay flat to dry. Avoid fabric softener — it coats fibers and reduces performance.

·Cashmere — Hand wash cold or dry clean. Store folded, never hung — hangers stretch the shoulders. Pilling is normal early on — use a cashmere comb.

·⚠ Beware ultra-cheap cashmere — short fibers pill quickly and lose shape. Look for 2-ply construction and long-staple fibers.

Sustainability

·Merino — Renewable, biodegradable, and requires less washing — reducing water use over its lifetime.

Cost Per Use

·Merino — Merino basics cost more upfront but last 3-5x longer than cotton equivalents. Less frequent washing also reduces wear and saves on water and energy.
·Cashmere — A quality cashmere sweater at $200 worn weekly for 8 years costs about $0.50 per wear. Cheap cashmere ($50) often pills out within a season — making it more expensive per wear.
·Priced around $100 (midpoint of $50–$150 for Apparel). At ~8 uses/month, this hits the $1-per-use "worth it" mark in 1 years — and falls to roughly 21¢ per use across a 5-year lifespan.
