Our fabrics combinations are tested by an independent lab verifying criteria levels before being offered in our line of products. We continuously research existing products to meet our performance standards. Throughout our traditional field testing, we have found a performance level that allows hunters to gain an advantage in keeping deer and other big game from detecting human scent. We’ve taken this level and engineered our fabrics to perform well above this level in order to give hunters the most effective system for scent-eliminating performance throughout the life of the garment.
