Choose Merino Wool Base Layers when…
You want natural temperature regulation, are on multi-day trips (odour resistance), want comfort across variable conditions, or have sensitive skin (merino is soft).
Choose Synthetic Base Layers when…
You're doing high-output sweaty activity needing fast wicking, want maximum durability, are on a budget, or need the fastest-drying option.

FAQ
Is merino wool worth it for skiing?
For many skiers, yes — merino regulates temperature across the variable conditions of a ski day (cold lifts, warm exertion), resists odour so it can be worn for multiple days, and feels comfortable. The downsides are higher cost and lower durability. Synthetic layers are a solid, cheaper alternative, especially for high-output activity.
Does merino wool smell less than synthetic base layers?
Yes — this is one of merino's most consistently cited advantages. Merino's natural lanolin and fibre structure inhibit bacterial growth, which is the primary cause of odour in sportswear. A merino base layer typically remains odour-free for multiple days of use; synthetic materials tend to retain odour after a single session and require washing. For multi-day outdoor activities where laundry access is limited, merino is significantly more practical.
How do you wash merino wool base layers?
Machine wash on a wool or delicate cycle with cold water (30°C maximum) and wool-specific detergent. Do not tumble dry — heat causes merino to shrink. Air dry flat or on a hanger. Merino does not need to be washed after every use — its odour resistance means it can often be aired out and worn again. Washing too frequently accelerates pilling and reduces the garment's lifespan.
