I just got the chance to try these out today and they. are. AWESOME. I haven’t been able to get my almost 2-year-old, 29 pound daughter into a pouch comfortably in ages, but this was the perfect combo of the simplicity of the pouch and the adjustability of a ring sling.
Although the directions say to do all the adjusting with baby out of the pouch, I popped dd in with the pouch a little on the loose side so I could squeeze her long and chubby legs through, then held her weight up off the carrier and snugged the adjuster straps up. (Pouch was sitting on my right shoulder so adjuster tabs were in front). The pouch spread nice and flat across my back and cupped my shoulder really well. Because it’s sewn together at the shoulder, a shoulder flip isn’t possible — but given the adjustability, it also isn’t necessary.
Having padding on both sides is really nice — no need to flip the carrier other way out if you’re going to switch shoulders! It also made it snug and cozy for my dd.
I think the adjustability factor will also help the issue some people have of needing to lower baby to nurse but lift baby higher for carrying, which can be challenging in a non-adjustable pouch.
I have rediscovered the pouch love!

you actually can flip the shoulder from the back. woot!
Cool beans! How does that work? I will have to try it out.
