When it comes to clothes that can be easily washed again and again, the word "machine-washable" is commonly used. However, if you're looking for alternative ways to describe the same feature, there are a range of synonyms you could use. "Easy-care" is a popular alternative, and "washer-friendly" could also work. "Wash-friendly", "washable" and "laundry-safe" are other options you might consider. Ultimately, the key is to choose words that will make it clear to your audience that the item in question is able to withstand the rigours of machine washing, without causing any damage or shrinkage.
