top rack dishwasher...

Yup I do a weekly rinse and air dry. This years might need to be replaced after the ne year. But I got a cheap bag

I have washed ours about every 2 weeks for 3 years. I put them in the dryer too (I thought air drying made them smell musty.

All the time. No dryer, but they dry quickly on their own. I just throw them in the regular wash Cycle on cold.

I washed a lands end one and the material inside ended up bunching. Had to throw it away.

I also wash ours all the time, too, with no problems.

I put in our Lands End and LL Bean ones all the time. No issues and we are going on year 4? 5?

I put mine in a mesh bag and then air dry.

I do.. no wash bag. Just throw it in the machine on gentle cycle, then air dry.

I put our PBK one in the top rack of the dishwasher.

I do ours all the time. Put it in a mesh bag on light/gentle cycle.

I wash ours a lot, but always inside a zippered gentle wash bag since I accidentally ruined my daughter's favorite lunch box (the picture cover frayed apart).

I set mine out to air dry and by morning they are ready to go.

I do all the time. It dries overnight.

I would be concerned that somehow water will seep into the lining. Unless there are no seams?

On gentle? And air dry it? I’m pretty diligent about wiping it out but something spilled in it and now it smells sour.

We have this one: https://m.llbean.com/llb/shop/70705?page=lunch-box&pn=pd&skCatId=70705
