I found it to be a great carrier for back carrying, so should be perfect for your DS's age. It also was a good fit for DH who is broad and tall, much better than the ergo for him. Only negative was no hood but your DS is big enough to keep a hat on what colour/pattern combo did you go for?

I won it in an auction, someone had it custom made for $180 and was selling it for well under $100 because her kid didn't like being worn. So, it's grey with cute little sugar skulls on it.
Waiting for the mail to come... It should be here today.
