Stasher Premium Reusable Silicone Food Storage Sandwich Bag, Clear, 28 oz

Why it's worth it

A thick platinum-silicone bag with a pinch-close seal that handles the freezer, the microwave, the oven and a sous vide bath. It's the rare reusable that does everything the disposable did, which is why it actually stays in rotation instead of in a drawer.

Most reusables approximate a plastic bag. This one replaces it. You can freeze soup in it, thaw it in the microwave, cook in it at up to 425°F, and run it through the dishwasher afterward. Stasher rates the silicone from -40°F to 425°F, so there's no moment where you think "this one needs a real container." That range is the whole argument for the price.

The seal is the part people notice first. You press it closed and it stays closed, which matters when a bag of marinating chicken is lying flat in the fridge next to your lunch. Owners who've had them for a year or more consistently report the closure still works — that's the failure point on cheaper silicone bags, and it's the one thing you can't fix once it goes.

What we like

• +Most reusables approximate a plastic bag. This one replaces it
• +The seal is the part people notice first
• +It also doesn't hold onto smells
• +Buy one first, not six

What to know

• –The sandwich size is honestly a little tight for a sandwich
• –Wet silicone is slippery, and opening the seal with soapy hands takes more grip than you'd expect
