Kuhl Men's The One Shirt-Jac

This style is designed as a do‑everything layer: light enough to wear indoors, warm enough for shoulder seasons, and rugged enough for active use. The outer fabric is wind‑ and water‑resistant, while the interior uses AERO™ KNIT insulation, a lightweight, thermoregulating fill that traps warmth without bulk. Underarm knit panels add breathability and stretch, making it ideal for hiking, travel, or everyday wear.
