## Long description

Buff Merino HW Over The Calf Socks HWO1 in Sea Green size S 39/41 are heavyweight merino wool socks designed to provide exceptional warmth, comfort, and moisture management during cold weather outdoor activities, hiking, and daily winter use.
Advantages
Constructed from heavyweight merino wool, these over-the-calf socks offer superior thermal insulation to keep feet warm in freezing temperatures. Natural moisture-management properties help keep feet dry by wicking away sweat, while the soft wool fibers ensure long-lasting comfort without irritation. The extended height provides extra coverage and warmth, making them ideal for winter boots and deep snow conditions.
Suitable for
Cold weather outdoor activities
Winter hiking and trekking
Daily winter use and commuting
Activities requiring extended boot coverage
When it may not be suitable
These heavyweight merino wool socks may be too warm for mild weather, indoor use, or intense summer activities where lightweight, highly breathable synthetic socks are preferred. They might also feel overly bulky in tight-fitting footwear designed for thin, low-profile socks.
Key specifications
Material: Heavyweight merino wool
Design: Over-the-calf height
Color: Sea Green
Size: S (39/41)
Intended season: Winter and cold weather
How to use
Pull the socks fully onto clean, dry feet, ensuring the heel sits properly in the designated heel pocket. Adjust the over-the-calf height so the fabric lies flat and smooth against the leg without bunching inside your footwear. Pair these socks with winter boots or hiking boots with sufficient internal volume to accommodate heavyweight wool.
What to consider before purchase
Verify that size S (39/41) matches your foot measurements
Ensure your footwear has enough room for heavyweight wool socks
Check care instructions for washing merino wool garments
Usage recommendations: Machine wash on a gentle wool cycle with a mild detergent and air dry flat to maintain the natural properties and lifespan of the merino wool fibers.
