Familiarity: I gave it as a gift but have feedback to share
I bought these as a gift for my 7 & 9 year old cousins visiting from Germany. They used them on our hikes in the Uinta Mountains and on their outings around town. I didn't realize that they came with a whistle. The kids found it and used it frequently so we knew where they were at all times. They fit them well and were able to hold all of the rocks and other treasures that they found.
