Stanley Ink 8 oz. Skull Flask ($20)
Doctors and scientists say drinking booze when you’re cold just makes you colder — but what the hell do they know? Which is why we recommend this leak-proof life-saver, which is slim enough to slip into any backpack or back pocket, yet still delivers eight shots of your favorite spirit. Plus, the stainless steel flask boasts a wide mouth to help even the hardest alcohol go down easy. And we defy you to write an equally dirty-sounding-but-not-actually-dirty sentence than that.
