Gütermann | 超強線 | 100 公尺 | #197 | 泳池藍

I needed to repair a heavy denim bag strap and this pool blue thread handled the stress without snapping, even after multiple passes on the machine. It's soft enough to work with easily but feels solid once sewn in.

The extra strong polyester held up perfectly when I re-stitched the shoulder strap on my heavy canvas tote. It stayed soft and elastic enough to work with easily, but the seam hasn't budged after a week of daily use.

I've been using this for my denim hems and it's held up through washing after washing without a single snapped stitch. The polyester is soft enough to work with easily, but the threads never seem to fray or weaken.
