Have you used an Ergo before? It's definitely lighterweight than a regular Ergo. I've been using it almost exclusively these days as our out and about carrier, and I like the hip belt, which seems a little narrower and less bulky but still supportive. I also like the longer length on the shoulder straps and hip belt as I can more easily get dd on over my heavy winter jacket and hers. It's just more convenient wearing her on the outside than using our babywearing jacket because of her age.
I've found it a little awkward using the sleeping hood as compared to the regular Ergo as the straps are pretty short (elasticized for some stretch, but still awkward). I also have to pay attention to make sure the shoulder straps don't get twisted as I'm putting them on, as for some reason I have a harder time keeping them straight.
Overall I think it's a good carrier and I'm looking forward to trying it out in the summer to see if it lives up to its billing as a cooler carrier.
