What to Consider

Materials & Construction

·Wool — Naturally temperature-regulating, odor-resistant, and moisture-wicking. Wool fibers bounce back to shape and can last years — making it ideal for garments worn frequently.
·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.
·Made by Allbirds in New Zealand.

Longevity & Care

·Wool — Hand wash cold or dry clean. Avoid high heat — wool can felt and shrink. Store folded with cedar to prevent moths.

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

Sustainability

·Wool — Renewable and biodegradable. Wool is one of the most sustainable natural fibers — it decomposes in soil and requires no synthetic inputs when responsibly sourced.
·Merino — Renewable, biodegradable, and requires less washing — reducing water use over its lifetime.

Cost Per Use

·Wool — A wool garment worn twice a week for 5 years can cost as little as $0.15 per wear. Wool's natural odor resistance means fewer washes, extending its life further.
·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.
·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.
