Share the adventure. Osprey want to inspire young people to enjoy the outdoors and the Osprey Youth Series is their way of doing this. Osprey knows by giving children the same level of pack fit and function as their grown-up counterparts that nothing will stop their adventures. Whether you're out camping or backpacking for the weekend, the Ace 50 provides your child with a light-weight fully functional backpack that rivals any adult sized Osprey pack. Osprey understands that children grow more than quickly, that's why they've equipped the Ace with an ultra-adjustable torso and Fit-on-the-Fly™ hipbelt. The Ace 50 will grow with your child providing them with years of comfort so you don't need to constantly replace their pack.
Keeping children cool when they're outdoors is key, that's why the Ace 50 has an AirScape™ backpanel with foam ridges for ventilation. It also has a LightWire™ frame and internal compression to ensure the fit is fine tuned to your child no matter how the Ace is packed. The integrated raincover means that even out in the rain their pack and contents are easily protected. The Ace 50 is suitable for ages 10-16 years.
A top buy for my 8 and 10-year-old children with long backs. It's worth measuring your child's back at home: from the protruding cervical vertebra to the height of the front hip bone. This adjusts to a back length of 36-46 cm (google torso length). It's nice to carry as it doesn't pack too much weight for the child. For us, two three-season sleeping bags and our own change of clothes were about 3.5 kg of contents in the backpack.

Really good features that are similar to adult backpacks, including a fully adjustable "hat" part of the backpack with straps, pockets on the belt, easy but sturdy back height adjustment, can be tightened enough even for a slim 9-year-old.

Nice smaller backpack for kids/women. Small piano but enough space and comfortable to carry.

Based on a hiking trip in Norway, this is a very well-fitting, lightweight and practical backpack for long trips. There is surprisingly much storage space and the adjustments are excellent. Unfortunately, I had to buy the rain cover separately.

A great first backpack for a young girl. Fits great now with minimal adjustments and has room to grow.

The best backpack for a 10-year-old. The adjustments are easy to adjust, and there is enough space. The high-quality materials guarantee that this will easily last for years to come until you need the next size backpack. Add some color for extra fun!

A good children's backpack that can be adjusted to fit at least every elementary school-aged child's back. Enough pockets and high-quality materials familiar from adult backpacks.
