Loring Pack Baskets are 100% handcrafted and will last a lifetime—guaranteed. The top rim, bottom runner skid, and inside solid bottom plate are made of synthetic polymers, which are impact, wear, UV, and chemical resistant, but still flexible. The weavers are also made of synthetic polymers, which are impact, wear, UV, and moisture resistant. The adjustable pack basket strap harness and the embroidered handle are made of 1½” UV and water resistant heavyweight polypro webbing. Loring Pack Baskets are fastened with 100% copper rivets and stainless steel screws. Because our pack baskets are made of a synthetic material you can be confident knowing that your pack basket will never rot, mildew, stain, retain odor, or crack.
