Smartwool Men's Beanies

Frequently Asked Questions

• How does the Active Beanie compare to the NTS Micro 150 Pattern Beanie for high-output activities like running and fast hiking?

  The Active Beanie is a lightweight, breathable option designed for runs and hikes with a slightly more structured jersey knit and moisture-wicking blends to shed sweat during higher output. The NTS Micro 150 Pattern Beanie is an ultralight, microweight base-layer option built from fine merino that excels when you need minimal bulk under a helmet or when layering for cold-weather workouts.
• Which Smartwool beanie is best for winter alpine use: the Merino Sport POW Beanie or the double-layer Smartwool Beanie?

  The Merino Sport POW Beanie pairs a warm merino interior with a more durable polyester exterior for added protection and insulation on cold, abrasive alpine days. The double-layer Smartwool Beanie (rib-knit) provides a snug, insulating fit with recycled-poly blends for everyday winter warmth and slightly more stretch for casual wear.
• How should I choose a Smartwool beanie based on activity—running, skiing, or casual wear?

  For running and high-output hiking choose the Active Beanie or NTS Micro 150 for low bulk, breathability, and quick-drying merino blends; the NTS is best when you want a true ultralight base layer. For skiing and colder conditions, the Merino Sport POW Beanie or the double-layer Smartwool Beanie offer more insulation and wind resistance. For casual and all-day use look for merino/Tencel blends that prioritize odor resistance and temperature regulation.
• Are Smartwool men's beanies compatible with helmets and how does fit typically run?

  Smartwool beanies are designed as unisex, stretchy, low-bulk hats and the jersey or double-layer rib knit construction allows easy helmet layering for most adult head sizes. The snug but flexible fit of models like the Active Beanie and NTS Micro 150 minimizes bulk under helmets while double-layer rib styles give a closer, warm fit for non-helmet use.
