Material disclosure
The supplier describes the material as polyurethane-coated split leather. The current maker page uses vegan, faux, and cruelty-free wording while also calling the material soft nubuck split leather. Those statements do not resolve whether the split-leather layer is animal-derived. The Stag Standard therefore does not represent this harness as animal-free, genuine full-grain leather, or any other exact leather grade. Check the label on the received product before relying on a material preference or restriction.
One-size guidance and fit
The maker’s current men’s one-size chart lists USA 28–40 and Europe 71–107, while the supplier calls 28–40 inches a waist range. The maker chart does not identify the body point being measured, so these figures are guidance rather than a chest measurement or fit guarantee.
Open or loosen the buckles before putting on the harness. Fit it over the clothing layer you intend to wear, then adjust the straps gradually and evenly. You should be able to take a full breath and move your shoulders and arms without pinching, numbness, tingling, unusual swelling, marked color change, or shortness of breath. Remove it promptly if any of those symptoms occur.
Hardware and use limits
No working-load, suspension, restraint, or fall-arrest rating was found for the rings, straps, buckles, or studs. Treat the hardware as decorative and suitable only for light, removable accessories. Do not support body weight, suspend, drag, forcefully pull, attach the harness to a fixed point, or use it in a way that compresses the neck or chest.
Keep a quick-release plan and make sure every buckle can be reached before use. Inspect the straps, coating, stitching, studs, buckles, and rings for cracks, sharp edges, looseness, tearing, peeling, deformation, or corrosion. Do not use the harness if any part is damaged or if removal cannot be done promptly.
Care and storage
Follow the product label first. The supplier directs hand washing separately in cold water, line or drip drying, and no bleach. Do not machine-wash, tumble-dry, use high heat, apply harsh solvents, or use an unverified leather conditioner. Spot-test any label-approved cleaner on a hidden area first.
Allow the harness to dry completely before storage. Store it unbuckled in a cool, dry place away from direct sunlight and heat so the coating and hardware are not held under unnecessary stress.
