What are the size ranges?

Probably best to go to Columbia's site and get the kids sizing chart there.

I would definitely go with medium. These are very tight. I was barely in the large range and there would be no way to get into the smaller ones for me.

I would think a medium but honestly you'd be better off going to a store and trying one on for size. There can be so many variables involved in fitting a pack its vital you get the correct fit otherwise you could end up disappointed. These are good packs, good enough to try on first before purchase, good luck.

I wear XL and there is enough room to spare for another size or 2 for sure. Hope that helps.

Small ... go up to the next size. I wore a 6 1/2 and got a size 7 and they fit perfectly.

They'll fit big. They are meant for an adult. I couldn't find gear to fit my daughter - but she's 7 and I think she'll love them!

Your best bet is to look at the Henderson website. They have size charts but I don't think they sell direct to the consumer. Hopefully they do metric as well. Good luck and a hui hou!

They fit the 2-4T range. I got this for my daughters 3rd birthday and it all fit her

Not sure on exact size range from the manufacturer....but I wear a men's size 9-1/2, sometimes 10, and I purchased the Medium size. Fits well, albeit snug due to the compression. I'm an average size male.

The size small fit my 3-6 year old boys and the medium fits the 6-9 year old range. They are youth sizes.

I would recommend 21 or 22 inches. When i was looking for my boys i investigated sizes and i remember that for 5-8 normally thats the size used. Hope this helps

I wear an extra large in shirts and there is plenty of room to expand further if necessary. No different sizes. Just one standard size.

They are adjustable in size. Size Small goes up to size 11. Size Medium starts at size 11. I'd go with the medium.
