5 must-haves for your next ski trip — all on sale at Amazon from $7

I thought that a hat and a neck gaiter would be enough warmth on the slopes — but it wasn't. Parts of my face were exposed to the harsh cold and that's all I could think about when skiing down the mountain (until my face went numb, of course). If I had a ski mask like the one pictured, I probably would have been a lot more comfortable. And this one has a 4.5 rating with over 27,000 reviews. Plus, at $7 it's way cheaper than the options they were selling at the ski store.

Other than my face, my fingers were the next coldest part of my body. Luckily, I had really warm ski mittens, but if I took them off for even a second, my hands would immediately sting. In retrospect, I wish I had some hand warmers for extra warmth. If I were you, I would opt for this variety pack that includes toe, hand a body warmers for just $7.

This one is just for fun — but it can definitely warm you up a bit in between runs. The stainless steel flask can transport your favorite drink or spirit and easily be stored in your pocket. Or, if you're like me, you can just head to the lodge for an après ski cocktail instead. Just don't overindulge!

Any old socks — regardless of how warm and fuzzy you think they are — will not do the trick. Wool socks are a must when you're skiing. I learned that a ski boot can be very unforgiving but fortunately, I was wearing wool socks so my feet were able to last for a couple of runs. I'm loving this set of merino wool ski socks that feature fun and colorful ski-inspired patterns. They have great temperature regulation and moisture control and can even prevent blisters.

I did make sure to layer up before putting on my ski clothes, but I think having some long johns or thermals would have really done the trick. With nearly 40,000 5-star reviews, I would opt for these thermals that customers praise for their warmth, comfort and quality. They're also fleece-lined, sweat-wicking and feature 4-way stretch. Women can snag the Thermajane Long Johns for the same price of $28. Just be sure to add the extra 10% off coupon.
