I currently have a Moby, a Hotsling, and a MT. I use the Moby 99% of the time. I love it, but it's too hot to use in the summer, and I think it may start to get uncomfortable the heavier he gets. However, nothing else I have beats it for comfort and feeling nice and secure. The Hotsling stays in the diaper bag for occasional use. I use a hip carry with that but hate how it pulls against my shoulder. It's uncomfortable. I think I could like the MT, but I have a crappy one. It has barely any padding and creates really uncomfortable pressure points that I can sometimes feel for days!
DS is about 22 lb. It gets really hot here in the summer. I only use front and hip carries now, but it would be nice to have the option of carrying him on my back. And I'm hoping to stay below $100. I *think* I want either a woven or a good MT, but I'm willing to consider any type of carrier. So, what do you recommend? (Extra points if you name specific sellers/brands. )
