Sub-Standard quality means that there is an imperfection in the thermal underwear and outdoor sportswear that does not allow us to sell the product for the full list price. It may be a fabric fault such as a pull, a dye/dirty mark, or a manufacture fault such as a missed stitch. Apart from that the product is produced exactly the same and will perform just as well as a first quality garment.
