Oh, I totally understand - buying your own gear is expensive, especially if you only go to the mountains once a year. It's especially hard if you only go to the mountains once a year. As for saving money, that’s true. I also recently booked through this site myself -
https://getski.com/ . And I like that they have the best deals - check it out if you haven't already. You actually pick up the gear right at the resort, which is convenient because you don't have to carry it on public transportation. The basic ski set usually includes skis, boots, and poles, but sometimes you have to add a helmet and goggles separately when you book. How many days are you planning to ski?
