What materials should I look for (or avoid) if I want sustainable clothing in Ireland's climate?

Ireland's climate rewards layering, breathability, and resilience.

Best-fit recommendation (materials that work):

• Wool/merino: warmth + temperature regulation (great for damp cold).
• Linen: breathable for indoor heat + summer; layers well.
• Cotton (higher weight): good for tees/sweats; check durability.
• Tencel/Lyocell: soft drape; verify source and blending.

What to be cautious with:

• 100% acrylic knits (pilling, static, microplastics)
• Very thin synthetics marketed as "technical" but worn as daily basics
• "Vegan leather" that's just plastic (unless the tradeoff is explicit)

Next step: Build a 3-layer system: base (comfort), mid (warmth), shell (wind/rain).
