PotN straps are dumb. (no offense, I like things w/o logos)
They are Optech straps but you can get better versions w/o the printing on them.
This is what I have:

you can also take off the padded part which makes the strap about half as long (basically for when you don't want/need a strap). You can also buy extra ends for them for $10 so you put them on each body you have and then have just one actually strap. Makes everything more compact and less straps to deal with in your bag.
