Personally I don't think their threads are very linty but maybe it is because I don't use it in the bobbin, I use Superior Bottom Line thread in all my bobbins.
I love the Connecting Threads and have been using them about 7 years.
Whenever I read about linty thread (no matter the brand name) I always wonder if the quilter is considering how much lint comes from fabrics and not the thread.
