Create an original 2026 t-shirt graphic for the hiking and outdoor niche called "Out of Breath Hiking Society." Use a vintage outdoor badge style with a mountain silhouette, trail lines, and bold readable typography. Keep the design clean, minimal, and print-on-demand friendly with earthy green, tan, black, and cream tones. Transparent background, no mockup, no realistic photo elements, no copyrighted content, no clutter.
