Familiarity: I returned this product before using it
Fit: Runs large
Full length zippers are uncommon and heavenly. Premium materials, minimalist design, and flawless assembly. The hook system at the waist holds well, doesn't rub, and allows a very small amount of adjustment in fit. The waistband is not lined for bare skin. On the inside, the ankle cuff lacks the burly reinforcement of the rest of the instep.
The fit is very generous in the seat, regular/slightly-trim in the thigh.
