The Easy Walk harnesses on my site are no-pull.
Barkaholics Premier Easy Walk Harness - SALE!
I like that they connect in the front because actually they can peek out of most hoodies (in the front) The front connector basically makes it so that when they pull it moves them to the side, so they are not rewarded for pulling by getting to what they want faster. I've used them on BIG dogs too
The first 2 are Loki's easy walk and the last one is his puppia vest harness.
