Your harnesses are what are considered Alpine Harnesses, designed to be light, packable. Generally used in things like glacier travel where you would rope up together, and perfect for your AR with short raps or tyroleans. But that's why they only have one strong point, as they would typically be used to biner directly into your belay loop, rather than a normal tie in. Not that they can't be used in a regular climbing setting, they will just be uncomfortable in long term hanging. Just make sure you always go behind your waistband if you do tie in, otherwise you risk flipping upside down if you only go thru the bottom leg loop strong point, is what I forgot to mention.
Good to know! I had asked since I was worried about flipping with just the single strong point. The harness wasn't as uncomfortable as I was expecting, although definitely not one I'd want to wear for any extended climbing.
