While these bags were inexpensive, they are roomy and they fit their gear (ski boots, helmet, mittens, goggles, jacket, mid-layer and ski pants with some small extras such as a balaclava) with some room to spare

I was able to fit my ski boots, as well as my 3 year old’s ski boots, 2 kids helmets, 2 goggles, 2 pairs of gloves and my makeup bag
