A short neck balaclava can work just fine, but it depends on when and how you're skiing. These designs cover just below the jawline, so they're ideal for mild days, spring skiing, or if you run hot and want less bulk under your helmet and goggles.
The trade-off is that a short neck style may leave your lower neck exposed, especially when you turn your head. Cold air can sneak in through the gap between the balaclava and your jacket collar. If you're skiing in genuinely cold conditions or hate any draft on your neck, you'll likely be happier with standard or extended neck coverage.
Short neck balaclavas work best when paired with a high-neck base layer or a jacket with a snug collar that fills in that gap. They're a smart choice for warm-weather resort days, but not the best pick for deep winter or backcountry trips where every bit of coverage counts.
