Rated 5 out of 5 by from My 3-1/2 son loves it! While I will divulge that I, myself am A faithful Osprey pack customer, this pack caught my eye in the store and was the smallest pack I could find (with a water hydration system compatibility) to fit my little boy. I am not disappointed in the quality or style. I am excited about the stretchy rain jacket pocket on the outside, the waist straps and absolutely LOVE the adorable hiking essentials list and depiction inside the pack. We initially got our 3-1/2 year old son excited to hike solely on the promise he would get to use (this) his "own hiking pack"! He now accompanies us at least once a week for hikes in the Arizona desert.

Rated 5 out of 5 by from Great for my preschooler We bought this pack for our 2.5-year-old so that he can carry some toys and his own water bottle on an upcoming plane trip and for him to use for preschool. It arrived and is well made, has nicely sized and easily accessible pockets and is the perfect size for him.

Rated 5 out of 5 by from Perfect Travel Bag I bought this bag about three weeks ago for my four year old son. He loves it. It is a perfect size for him and has a setup for a water bladder. I did buy the bladder and that makes it awesome for family bike rides. This bag is just incredible and he won't leave home without it.

Rated 5 out of 5 by from Fits toddler really well I bought this for my 2 year old to hold all his things while we travel. I had originally looked at smaller bags designed for his age, but they all seemed to be just too small to fit his things. This pack says that it is designed for children age 5-8, but it fits my 2 year old perfectly! My son is just a little over 36" tall and a little under 30 pounds. The length and width fit him perfectly! Plus he loves the little essentials picture on the inside of the bag :)

Rated 5 out of 5 by from Great all around pack I bought this for my son to replace a school bag that fell apart quickly. It has held up to the daily abuse from a kindergartener and has worked well for his Cub Scout trips also. It's a great value and very durable and makes him feel like a big kid.

Is this pack actually for 8-12 year olds or is it more appropriate for 5-8 year olds (as the discontinued 12 L REI pack was)? Would this work for a large preschooler?

Asked by: Katie001
Tried this pack on my 12 month old son in the store today for fun and it fit him great.  Would work far better for a preschooler than 12 year old!

Apologies for a question that has been somewhat answered already. I am an adult female only 4'10" tall, looking for a lightweight, small backpack for day trips to events, only need capacity of a medium purse. Will this fit me? Otherwise, suggestions?

Asked by: KDavis
I'm also looking for a small backpack to use as a casual daily purse. I tried the 12L size on the store and all the straps were adjustable enough to fit me. I'm 5'3 and size 4/6. The waist strap rides a little high of course. The only reason I didn't buy it is because the store only had the pink bag in stock.

I'm looking for a lightweight back pack to use as a purse. Would this fit an average size female adult for that purpose? I love the colors!

Asked by: Beccbridges
This pack is intended for 5-8 year olds so it will most likely be too small for an adult female. Without knowing your measurements we would be unable to confirm if this pack will fit you or not.

Would this fit my 12 year old daughter????? We are going skiing and I need a pack for her to use.

Asked by: SkierLady
This pack will fit your 12 year old daughter. That said, the pack has an age range of 5 to 8 years old and only has a gear capacity of 12 liters. The Tarn 18 might be a better choice as it is recommended for kids ages 8 to 12 and has 18 liters of gear capacity.

I'm reading what seem like mixed reviews on whether this could work as a school backpack for a kindergartner.  Does it fit a standard sized folder?

Asked by: jkentmc
​An 11" x 8 ½" x 1 1/2" book will just fit in the pack and be able to zip it up.
