I am thinking about getting a backpack-style bag to carry my boots and skis. I have seen a bunch of bags online that are for boots, but I was also hoping for a bag that I can attach my skis to and carry on my back. Any recommendations?
In terms of usage, the primary motivation for me is that my son is four, turning five in January, and I am planning to take him skiing (hopefully) many times this season. The game plan will be me taking him to a small hill sans wife. Having the skis and boots in the bag will allow me to carry his gear and keep a hand on him (I hope).
Depending on how big your kid is, a backpack might be unmanageable for him.
I had my two kids carry their own skis (arms stretched out in front, palms up, drop the skis on them), and I carried everything else in a big army surplus duffel. I think having them carry skis like that also immobilized them a little, and made it less like herding cats. It was just awkward enough for them that they headed directly for the lodge, instead of their preferred option of inspecting the snowmaking pond first. When they got a little bigger, I gave them boot bags. I never let them carry my poles. That would have ended in a light saber fight. YMMV.
I did Harvey's method. Whatever you do make sure the kid starts to carry things early on so as they age they can take all of their own equipment. But, if you can, by far and away thr best option = a locker in the baselodge.
