Reusable zipper bags are becoming more and more accessible — not only can you find them at home stores and zero-waste lifestyle shops, but you can also find them for sale in big-box stores like Target, Walmart, and the Container Store. These bags are typically made of either silicone, reusable plastic, or even fabric, and there are advantages and disadvantages to each kind.

Of course, reusable zipper bags are great for taking snacks on the go, freezing leftovers, and even cooking — but are also useful outside the kitchen. For instance, many of them are TSA-approved for storing toiletries in your carry-on during air travel.

So, we’ve rounded up a few of the standout reusable silicone Ziploc bag alternatives out there, starting with the Kleenex of them all: Stasher bags.

Stasher bags

Certified B corp Stasher makes its reusable Stasher bags out of 100 percent silicone in all different colors, sizes, and patterns. The bags are safe to use in the freezer, microwave, dishwasher, oven, boiling water, and even in a sous vide machine. Stasher guarantees that the bags will last a lifetime, but should your bags ever rip, you can mail them back to the company to be recycled.

Stasher bags can freeze anything from leftovers to fresh bread, they can be tossed in the microwave to quickly defrost frozen food (just make sure to vent the opening), and they look much cuter than a Tupperware when taking snacks on the go (plus, they take up far less space once they’re empty). You can order from Stasher’s website or find them in stores such as Target and Whole Foods, with prices ranging from $7.99 to $29.99.

Zero Waste Outlet’s leak-proof silicone bags

Zero Waste Outlet is a family-owned and operated company that ships everything in minimal, zero-waste packaging, and a three-pack of the bags (two medium and one small) goes for $24.99, but is on sale for $19.99 as of publication.
