Gutermann Mara 70 is the best thread choice for sewing MYOG gear with a home machine using standard needle sizes.
Though heavier duty than the typical polyester or polyester wrapped threads found on store shelves, Mara 70 still feeds smoothly through the machine and needle with no issue.
I have built two backpacks from coated Robic 210 and similar tough coated fabrics. The thread feeds reliably through multiple layers of these durable fabrics without fraying. Same positive outcome when zig zag bar tacking through multiple layers of nylon webbing. Breathable rain gear, ultralite silnylon tarps, a bunch of stuff sacks, fanny packs, all sewn using Mara 70.
I made a two person ultralite tent from 1oz and 1.43oz Dyneema fabric. Mara 70 was a great choice for every tent body seams, as well as sewing the finicky noseeum door panels and zippers.
Great all purpose thread. Tom
