Endlessly reusable Stasher bags serve many purposes in many places. I keep Stashers in my backpack full of snacks and tea bags, in my freezer full of smoothie supplies, and bring them with me when grocery shopping for the bulk bins. And, if I’m traveling, I always have at least a few on me for storing my makeup, bringing healthy snacks, and carrying supplements.

I started to think about all the ways I could use Stasher bags, and I just couldn’t stop! As a sustainability junkie, it’s kind of fun to think of all the possibilities. So, I am sharing 50 ways you can use your bags—from the fridge to the freezer, backpack to the beach, and lots more!

For Food

1. Keep food fresh in the refrigerator—half an avocado, chopped veggies, tortillas, or donuts.

2. Store leftovers from a home-cooked meal.

3. Make Stasher a to-go container if you take food home from a restaurant.

4. Bring a few to the farmer’s market to fill up with greens, berries, or any loose items that need a bag.

5. Fill up in the bulk section of your grocery store, just make sure to weigh it first to get the tare weight. I’ve used mine so much I have them memorized: Snack: 56g, Sandwich: 70g.

6. Pack a low waste lunch or snacks for a road-trip, beach day, or the zoo.

7. Portion out “smoothie packs” for the freezer.

8. Steam vegetables in the microwave or boiling water.

9. Marinate meat, fish, or veggies.

10. Stash and mash zesty guacamole.

11. Make your own ice cream.

12. Steam and smush nutritious produce for healthy homemade baby food.

13. Make the perfect steak with the sous vide cooking method.

14. Quick pickle some veggies or make homemade sauerkraut.

15. Keep food scraps in the freezer for a future broth.

16. Portion out freezer meals, like chili or soup. Store your full Stashers horizontally to save space. Pro tip: Write the date on the matte side of the bag with a ballpoint pen or dry erase marker—it wipes off with a damp cloth!

17. Pop popcorn in the microwave.

18. Make an omelet or scrambled eggs.

19. Revive stale bread in the oven.

20. Make chocolate bark! Melt some chocolate in your Stasher in the microwave, then add nuts, seeds, adaptogens, or berries. Freeze flat.

21. Bake an assortment of veggies for an easy, healthy meal you can take on the go!

22. Bring healthy snacks or candy to the movies.

23. Replace your salad jars with salad bags.

24. Keep your loose leaf tea fresh.

25. Freeze cookies, muffins and pancakes to eat individually when you want them.

26. Use ice cube trays to freeze leftover nut milk, yogurt, smoothies, or herbs in olive oil, then store them in your Stasher for easy add-ins while cooking or blending!

27. Infuse tea, liquor and other beverages.

For Adventure

28. Store your low-waste items in a Stasher bag, like your reusable straw, utensils and produce bags, and pop it in your tote or backpack so you’re always prepared to refuse single-use plastics!

29. Pack your liquids and toiletries in a Quart Stasher bag to bring on a flight.

30. Keep your travel essentials all in one place for the airport, like your passport, boarding pass, earbuds, visas, and customs cards.

31. Protect your electronics (phone, headphones, camera) while at the beach.

32. Keep your car keys or phone safe around water.

33. Fill it with ice and use it as a cooler pack.

34. Store your compost on the go and then throw it in your compost pail when you get home (like banana peels and cherry pits).

35. Fill with first aid supplies to have on hand at any given time.

36. Organize your makeup to bring with you in your backpack or suitcase.

37. Protect your essential oils while on the go (super helpful in case they spill!).

38. Bring your vitamins, prescriptions, or supplements on a trip— you can bring the bottles in a Half Gallon or Quart Stasher bag, or just bring the pills you need (if you can identify them!) in a Snack size.

39. Bring your epsom salts with you on vacation for the ultimate spa bath without having to bring the whole bag from home.

40. Keep your wet swimsuit separated from dry clothes in your travel bag.

41. Contain the heat from your hair straightener or curling iron if you have to pack it in your bag while it’s still hot.

For Home Life

42. Use as a heating pad. Fill it with rice and stick it in the oven or microwave. Great for cramps or after the gym.

43. Fill with ice and use as an ice pack for injuries.

44. Store DIY reusable baby or makeup wipes.

45. Store dog treats for walks with your pup!

46. Organize arts and crafts supplies—keep clay or paint from drying out, corral small tools, markers, brushes, pencils, and erasers.

47. Store your kids’ legos and other small toys.

48. Create DIY sensory play for your kids using water and squishy toys or sliced fruit.

49. Store and sanitize breast pump parts.

50. Mix and store DIY body scrub.
