You ever think about how many disposable sandwich bags are thrown away every single day? All that plastic, used just once, only to end up in landfills and oceans to not-decompose for the next few thousand years. It's horrifying, isn't it?

In our ongoing search to find alternatives to single-use plastics, we've written about products like the Planet Wise reusable zipper bags, which are great for loading up with sandwiches and simple snacks the day you're going to eat them — but what about when you need to store food in your fridge for a few days, or marinate ingredients for a dish? What if you want to sous vide a meal?

That's where Stasher's reusable silicone bags come in. These are more like the airtight, zip-lock style bags you're familiar with, except they're made from platinum-cured silicone, a non-toxic food-grade material with very high tensile strength and resistance to temperature extremes. It's virtually indestructible stuff as long as you properly care for it.

What that all means for you is, these bags are microwave- and dishwasher-safe, they can be used in the oven (up to 400°F) or boiling water, you can freeze them, and yes, they work for sous vide. They're even travel friendly.

They've got a bunch of sizes to suit your needs (from largest to smallest):

• Half-gallon (64.2 oz) — $20
• Sandwich (15 oz) — $12
• Snack (9.9 oz) — $10
• Pocket (4 oz) — $14 for two-pack

Each one comes in a variety of colors, in case "clear" is purely boring to you. They also have a two-quart (56 oz) "stand-up" version that...well, stands on its own, offering its own set of uses.
