Question: What are the covers made of?
Document: If you are looking for some lightweight clothes covers, this set by Ikea may fit the bill. These are lightweight: they are not made for durable, long-lasting use during transport, but rather for keeping a lightweight cover over suits and dresses while they hang in the closet. But if that's all you need, these will serve well, and the cost is good, too.
These clothes cover are made from flimsy thin plastic like material. Not the best for traveling but great for keeping dust out.
It covers my grandchildren clothes, which is what I needed.
The zipper isn't great, but these are not expensive clothing covers. You are able to see the clothing through the covers which is helpful.
These coverings were very thin and ripped easily. There are two different weights of IKEA clothing covers, I was led to believe they were the heavier weight ones.
Wonderful clothes covers. Perfect in every way. So nice to cover off-season clothes w/ these covers. They are lightweight, but sturdy and I'm very pleased w/ this purchase.
These covers have helped me organize. The variety pack is good for all lengths of clothing. They aren't the best quality but they do the job. Mine haven't ripped and the zippers haven't broken but I've been extra careful with them.
These are probably not the most heavy-duty covers that you could find, but for the price they are just perfect. The zippers are all sewn in nicely and the do the job for far less money than some of the alternatives that I saw when looking for them.
&#34;OK&#34; Quality Ikea Garment/Clothes Cover. It is not fully transparent, it is translucent. It is thin and I am not sure how long it will last. Will update after frequent use. I miss my SYMS clothes and garment covers.
The longer covers will fit a trench coat or lady's dress. The shorter ones are suit length. They are perfect for covering your winter clothing up and hang in the closet. The covers are fairly thin so I don't think they can provide much protection if you intend on using them for travel.
Answer: They are made of a plastic material. Used them for my destination wedding and they worked great for traveling.
