Selected construction detail
Crew neck: A close, clean crew neck keeps the base layer secure under a collar or hood without adding visual noise. Rib depth, recovery, and final collar measurements require final detail review.
The Obsidian and Frost views are clean product assets for this colorway. They communicate the garment design and visible construction intent; the Performance compression blend, 4-way stretch, moisture-wicking, flatlock seam, and fit claims require final detail review before being treated as verified performance specifications.
