CORE CREW
A three-axis fabric architecture: merino next to skin for moisture transport, a mid-knit synthetic for structural integrity, and a face-treated nylon shell for wind resistance. The seams are bonded, not sewn. The result is a garment that disappears at body temperature.

STRIDE TIGHT
Engineered for athletes who generate heat under load and need to keep it. A 4-way stretch chassis holds compression at pace without restricting gait. The knee panels are reinforced with a 280 GSM grid-knit that doubles as a kneeling surface on alpine terrain.

RIDGE BALACLAVA
The face opening is a variable geometry — cinch the cord and it seals to a 2cm aperture for summit conditions. Open to full face-frame for the approach. The crown is a single-piece merino knit with no seam at the pressure point of a helmet liner. Designed to disappear.

VISCERAL
Body heat rendered in thermal imaging. Magenta bloom represents retained heat at core and extremities after 90 minutes at −25°C.

"Pulled the Core Crew on at 3 a.m. in a headlamp cone on the Frendo Spur. Didn't think about it again until the summit."
"Stripped my shell at the trailhead and the Stride Tight held heat through 40km of skate skiing. Zero wind penetration at the thigh."

"Roads went black ice at 5 a.m. The Core Crew under my shell was the difference between turning back and finishing the century."

"The Ridge Balaclava sealed to 2cm at the Col. I couldn't feel my face. Then I could. That's the point."
"I wear this 8 hours a day, 5 days a week all winter. The merino doesn't stink. The seams don't move. That's all I need."

"WI5 in the amphitheater at 4 a.m. Core Crew Pro under a single shell. Hands were the problem. Everything else was fine."
