I found the Ergo comfortable but it got pretty hot.. the body is heavily padded and thick. I loooove wrapping
but an SSC will probably be more convenient for hiking and camping, and it allows for a little airflow between you and baby so will keep you cooler than most wraps. Is there a store near you that sells Ergos or Becos that will let you try them on before buying, or a local BWing group that has carriers you can try? Either of those would be a good place to start so you can get an idea of what you like. There is a mind-boggling number of different SSC brands that all have slightly different body sizes, waist and shoulder styles, etc... so if you don't like the Beco or Ergo there are definitely other options if you search for them.
If it's going to be warm, you might consider finding an SSC with a solarveil panel to keep you and your DS cooler. Bamberoo makes awesome mei tais and SSCs with solarveil panels, but you may have to do some searching to find one (like many of my favorites, they're made by a WAHM who does custom slots, she occasionally has in-stock carriers but they typically sell out pretty quickly). Check out the FSOT board on thebabywearer.com if you don't mind used carriers, you can get some great deals there. You can also put up a post in the In Search Of forum on TBW, but you have to meet a 30 days/30 posts membership requirement to access it.
Another option if you're looking for a carrier that's easy to buy new: a solarweave Connecta (here: http://www.connectababycarrier.com/c...php?category=2
). You have to buy the lumbar support separately for the Connecta, and I'd probably spring for it for a big baby/long periods of wearing.
Olives and Applesauce is another brand that I've heard wears similarly to the Ergo, but it's prettier and the body is not so thick. You can buy through O & A directly or through one of the vendors linked on her site.
HTH some! I'll come back if I think of anything else
