GSI Outdoors Boulder Flask
This clear case may look fragile but the Boulder Flask from GSI Outdoors is completely shatter-resistant. The silicone grip keeps it from slipping (especially helpful if your hands or wet or sweaty) and the top remains connected to the body, so you can never lose it. The flask itself is 4.3 ounces and it can hold 10 ounces of liquid.
Vapur Incognito Flask
The Incognito’s low-profile design, available in either teal or black, is as flexible as it is simple. The BPA-free flask allows you to discreetly tuck 10 ounces of fluid in your bag or pocket when traveling. When you’re done, quickly run it through the dishwasher. The bundled pourer and freezer-safe components only make it that much more enticing.
Stanley Classic Flask
Seattle-based Stanley remains a touchstone in the realm of travel-ready drinking utensils. The company offers a variety of flasks and booze-related gear, but we’re partial to the Classic Flask because it’s stainless steel (so it won’t rust) and compact.
Nalgene is a long-standing cornerstone when it comes to containers. The company’s apt-titled Nalgene Flask features a 1-ounce cap and a rugged insulation sleeve, allowing you to stow 12 ounces of your favorite liquid within an assortment of colorful designs that pair well with any pack. And if you drop the sleeve, it weighs a mere 1.86 ounces.
Bush Smarts Hip Flask
Bush Smarts Hip Flask straddles the line between form and function. The flask’s no-frill design capitalizes on a basic build made of PE-HD thermoplastic. The 1.5-ounce capacity container even has a leather fob and waxed cord stitching, giving you a quick means for attaching it to your belt.
Platypus PlatyPreserve Portable Wine Bottle
We’ve focused on personal-size flasks thus far, but if you’re stockpiling larger amounts for your trip, then this affordable option from Platypus is the way to go. It conveniently holds 27 ounces, which is enough room for an entire wine bottle, but we imagine your favorite spirit will fit as well.
Snow Peak Titanium Round Flask
Snow Peak has as much a penchant for design as it does cost. As one of the smallest flasks on our list, the company’s titanium container is a prime example of said vision. The polished flask lets you pack 6.7 ounces of liquid into an attractive build that’s designed to curb metallic flavors and unnecessary weight (at a premium price).
