Stanley Packable Shot Glass Set $20, shopstanley.com (available Fall ’14)

Few things are better than summit shots, but sipping from the same flask of whiskey is like making out with everyone on your trip. Depending on your crew, that might be fine, but as a whole I’m betting that last sentence made you cringe. Which is why we like Stanley’s Packable  Stainless Steel Shot Glass Set: four stainless steel shot glasses that stack up and fit into a container that’s a bit smaller than an empty toilet paper roll. No room in your pack? No problem: the steel case has a loop on its screw-on lid, so you can clip it to the outside of your pack. Cheers.
