As a single parent who grew up slalom racing, I wanted to afford my son the same opportunity. Since it is just the two of us, I bought this pack to help me carry both sets of skis so I could carry our boots with one hand and the other to keep him from slipping on the ice. Its great because now I don't have to make two trips to the car. Since he is only 4, there was no way he was going to be helpful in carrying the gear. I had no problem fitting a 1L hydration bag, extra gloves, tons of snacks, etc. I wouldn't want more space bc I think its hard to be skiing with a sloppy, heavy bag. I was impressed with quality, although the orange belt was too hard to disengage so i just carry a bungee cord. I know this was not the intention of the bag, but for what I needed it for, it was well worth it. I do find it is easier to fully pack the pouch, load the skis onto the bag and put them in the car attached. This way I can do a day trip, get him out of the car, throw on this bag and the boot bag and be on our way to the slopes in less than five minutes.
