Mettler Xtreme Pro thread in Swamp is a bonded polyester sewing thread for outdoor and upholstery projects. Supplied on a 400m spool, it combines a neat textile appearance with resistance to tearing and abrasion, helping you create durable seams on items that receive regular use.

The Swamp colour offers an alternative to standard black or neutral stitching. Choose it to complement your fabric or create a contrasting seam on bags, covers and upholstery. Check the product photographs against your project before ordering, as colours can appear differently on screens.

Outdoor and Upholstery Applications

Use this thread for projects such as upholstered furniture, outdoor cushions, heavy curtains, awnings, boat covers, tents and bags. Its resistance to wear makes it a useful choice when seams need to cope with repeated handling.

Match the thread, needle and machine to the material being sewn. Before starting your finished item, sew a sample through the same number of layers to check stitch formation and adjust tension as needed.

Why Choose Mettler Xtreme Pro?

The bonded polyester construction provides strength for demanding sewing projects. UV and seawater resistance help support colour retention outdoors, while the PFC-free water-repellent finish helps the thread resist moisture.

Water-repellent thread does not make a finished seam waterproof. Projects such as tents and covers may also require suitable fabric, construction methods and seam sealing.
