Bear thread is a heavy duty sewing thread that has long been used in sewing applications where extra durability is required. The name comes from the bear that adorned the original English-made product. The thread is specifically designed to provide strong and durable seams in applications where the joint between fabric details is exposed to high stress.

Bear thread is used, among other things, in sewing outdoor garments, tent cloth and other heavy-duty materials where the seam must withstand stress for a long time. It has also been traditionally used as a meter rope due to its high strength and durability.

Today, the closest we come to the classic Gütermann Extra Strong bear thread is a modern, durable sewing thread developed for demanding sewing and repairs where strength and durability are crucial.
