I'm 6'3 250lbs and hunted sit drag all last season. It's OK stock but can be tight on the side of your hip after long sits. I used a RC(rock climbing) harness as an additional safety and climbed with a custom llinesman's belt I made from an extra tree harness that came with a stand. Also added foam padding to line the seat. Very comfortable after adding the padding and once bridge length was adjusted to my comfort. Some people might only use the sit drag but I strongly recommend a harness. They are not expensive, mine was 30$ and super light, barely know it's there but will be thankful when you need it.
