We have enjoyed the carrier but have only been able to use it a few times. It fits my 6' husband well. No noted problems yet. One of the best features is the large and comfy pillow. Our son has fallen asleep on every hike! There is ample storage capacity for baby and parents things. The ability to add a water bladder is also a really nice feature. We were given the Kelty 3.0 carrier as a gift and decided to exchange it for this Deuter. We seem to have made the right choice. So far, we would highly recommend. Oh, just thought about one negative....the built-in sun/rain canopy is great (a big selling feature for us)but when we fasten it down our son gets shoved into the pillow. He is only nine months, though, and we don't think this will be a problem once he gets a bit taller! (and hence, his head will be above the pillow).
Best child carrier available
I tried several other child carrier backpacks, including the other models by Deuter, and the Kid Comfort III is hands-down the most comfortable and well constructed child carrier backpack on the market. While it is one of the priciest, your back and shoulders will thank you for not buying one of the other models. No other models have as comfortable of straps as the Kid Comfort III does. The adjustable harness system also allows you to switch between users in seconds, without having to completely re-adjust all the straps, which you have to do with other models and brands. Also, Deuter is the easiest to take your child in and out of -- simply undo one buckle, loosen one strap, and then the carrier pivots open on a hinge allowing you pull your child out easily. I'm 6'3", 180 lbs. and have used the Kid Comfort III to carry around my 18-month old. It takes some time to adjust straps, etc., to get the fit just right, but once you do it is surprisingly comfortable to carry that much weight around. Once adjusted, you should have most of the weight on your hips, though there will still be some pressure on your shoulders. The first few times you use it, you will want to take frequent breaks and take the backpack off and let your child down. However, after using it for a while I have been able to hike almost 3 miles without having to stop and take a break. One note: it is helpful to have a second person help you put on and take off the backpack (with your child in it) the first few times you use it, as it will be fairly heavy and awkward to put on and take off by yourself. One downside to the backpack is that because of the waist strap, you can't carry anything on your belt, such as a knife, flashlight, camera case, water bottle holder, binoculars, etc. However, there is a good size pocket built-into the waist pad that can hold a small digital camera or cell phone. The waist straps are also wide enough that I was able to use the parts of the waist straps that extend beyond the waist pads to hold my digital camera case and a small flashlight case. There is also a pocket on the waist pad that has a small mirror Velcroed in that you can use to check on your child while he/she is on your back. There are 2 zipper pockets on the back, the main one of which you can store quite a bit of gear. There are no internal dividers or pockets in the 2 zipper pockets, but the smaller one does have an attached hook inside which is great for clipping on your keys. There is also a good size outer pocket above the top zipper pocket that is great for storing a sweater, extra shirt, etc. One of the best parts is the hydration pocket that can hold any 70oz. hydration bladder. This works great since there really isn't enough room to carry a large water bottle in the backpack. You could probably fit a water bottle in the large zipper pocket, but since it isn't as easy to take the child carrier off and on like a regular backpack, it is better if you invest in the hydration bladder and you can take a drink whenever you want. The sun hood is great to keep your child shaded, and is permanently attached and folds away into its own zipper pocket, so you never have to worry about whether you should bring it along or not. The kickstand locks solidly in place once it is open, but depending on how you have the backpack adjusted, it can sometimes fly open while you are carrying it. I just wish there was some type of Velcro strip attached that would keep the kickstand closed. Overall, it works great for allowing you to be able to take hikes with your kids and is much more functional than a stroller, because anywhere you can hike on foot, you can bring your child.
