Arc'teryx Stonecat Hat
The Arc'teryx Stonecat Hat (Model #11820) weighs 54-56g and uses a 50% wool, 50% acrylic blend in a fine-ribbed knit construction. Released around 2012, this low-profile beanie features a fleece-lined headband, subtle four-stripe detail, and five-dart shaping that creates one of the cleanest silhouettes in Arc'teryx's discontinued lineup.
The wool-acrylic blend balances natural warmth with synthetic durability. Wool regulates temperature and resists odor, while acrylic maintains shape and dries faster than pure wool. The fine-ribbed texture gives the Stonecat a refined look that works equally well on the mountain and around town.
What Are the Arc'teryx Stonecat Hat Specs?
The Stonecat weighs 54-56g, depending on colorway, placing it in the lightweight category alongside the Geometric Beanie at 54g. The five-dart construction differs from the more common four- and six-dart designs, resulting in a slightly different crown shape. The fleece-lined headband sits against your forehead and ears for itch prevention and moisture wicking.
Arc'teryx produced the Stonecat in limited colorways, including Blue Moon and Wolfram. The four horizontal stripes near the brim add subtle visual interest without the bold patterns of models like the Charlie Toque or Nordiq Hat. The embroidered logo keeps branding minimal.
How Does the Arc'teryx Stonecat Hat Fit?
The five-dart construction creates a close, contoured fit that hugs your head without excessive material. At just over 6 feet and 165 pounds, I find the one-size design works well for my head shape. The fit runs snug like most Arc'teryx toques, so larger heads (60cm+) may find it tight.
The low-profile shape sits close to your skull, making this one of the better options for wearing under helmets. No bunching or pressure points when you strap on a ski helmet. The fleece headband adds comfort without adding bulk around your ears.
How Warm Is the Stonecat Hat?
The 50/50 wool-acrylic blend handles temperatures from 20 to 40 ° F during moderate activity. The single-layer construction with fleece headband provides enough insulation for resort skiing and fall hiking, but won't cut it for stationary use in deep cold. For standing around in sub-20°F temps, you'd want something heavier like the Castlegar Toque at 110g.
The wool content provides natural temperature regulation that pure acrylic lacks. When you're working hard on an uphill skin track, the Stonecat breathes well enough to prevent overheating. When you stop for a break, the wool traps warmth better than synthetic materials.
How Does the Stonecat Compare to Similar Models?
The Geometric Beanie shares the same 54g weight and wool-acrylic construction, but features bold geometric patterns rather than subtle stripes. The Stonecat's cleaner aesthetic works better for everyday wear.
The Diplomat Toque at 40g offers similar refined styling in pure merino wool, but weighs less and resells for more. The Stonecat's wool-acrylic blend is more durable for daily use.
The Bird Head Toque at 57g uses a similar 50/50 merino-polyester blend but with the massive jacquard logo that makes it instantly recognizable. The Stonecat's understated design appeals to people who want Arc'teryx quality without obvious branding.
Is the Arc'teryx Stonecat Hat Worth Buying?
For a refined, low-profile beanie with solid construction, yes. The five-dart shaping and fine-ribbed knit give the Stonecat a cleaner look than most Arc'teryx toques. The 54-56g weight and helmet-compatible fit make it practical for skiing and hiking.
The Stonecat is discontinued and uncommon on resale platforms. The Smartwool Merino 250 Cuffed Beanie offers a similar wool-blend construction and is currently available if you can't find a Stonecat. Expect to pay $30-50 when one appears on resale. Check interior tags for the 50% wool, 50% acrylic content and Model #11820 to confirm authenticity.
