Read the Garment's Label for washing instructions

I will assume that it works because my Gortex wearable gear lasts for years. However, make sure that prior to using this product, you read the garments' label w/washing instructions. If instructed to use powdered detergent only then don't use this or any other liquid detergents or additives for washing. Ironically, from speaking with Columbia Sportswear and NorthFace customer service agents, when the label specifies "gentle, powdered detergent only" it's because w/certain garments liquid detergents, including wash-in waterproof restoring products, actually "clog the pores" causing deterioration of the chemicals used to create waterproofed items.

Fit is fine but the medium label that was down one of the legs has left a large mark that I can't remove and it looks twrrible

After I bought these I looked a little more closely at the models, this "Easy" khaki is a washed and soft material.  I would have rather had their "Signature" material, but the ones I bought still work for work.

perfect fit. would be nice if item had washing instructions and it would be nice if item had the fiber content. Not sure how to wash.

Remember wash in cold water to keep the fit...

Nice looking shirt overall.  The description says "machine wash cold with like colors", but the tag says "dry clean only".  I would not have bought this shirt if the description says "dry clean only".  I have not tried to wash the shirt yet because I don't want to ruin it.

The shirt had a bad packaging smell, so put right in wash, It came out with what looked like dirt smeared along the left bottom, put back in wash now it looks like a rust stain.  Nothing else in laundry affected it was his shirt specific.  Dont know what a third wash is going to get me but not looking good.

Instructions are somewhat vague in places, but the garments described were nice and easy to make once you get the hang of it. Images have words that didn't get translated; I had to use Google Translate but was not a huge issue.

The size and clarity of the print is good. Unfortunately some of the labels started coming off after just one wash. These were purchased to put inside of clothing for my mother who resides in a long term care facility. If the label falls off then her clothing is lost.

This sweater seems nicely made, is soft, attractive, and fits well as expected for the chosen size. The zipper at the back neckline makes putting on and taking off the sweater so easy.
Week later - the ad description on Amazon says: "Machine wash & dry". The care tag says: "Machine wash cold.....gentle cycle....remove promptly reshape and lay flat to dry cool iron". I never buy a garment that I can't throw in the dryer. This was a disappointment. Wish I had read the tag upon receiving the sweater. I may not have kept it, in spite of its other nice features. So I changed the rating from 5 stars to 3.

Love the shirt. Love the fit. The real test is usually after the first wash.

Love this shirt! it fit great and it's super cute! But be sure to read the washing instructions. I put it through the dryer and the picture wrinkled a little so be sure to air dry it. But other than that it's a favorite in y wardrobe.

Worked as described. Be sure to handwash. I didn't read instructions.

its a very versatile item. its useful in virtually every situation from carpentry and keeping saw dust out of your mouth and ears to snowboarding and keeping your face warmed up. However, if you wash it, wash it alone. it will bleed into any color clothing you have. i washed the red one with dark clothes and it turns dark blues purple, dark greys have a pink hue. i looked every where on it and there is no washing instruction tag on it anywhere so i had no idea.

Haven't washed it yet, but I love it so far.  Hopefully, I will still love it then.

Why does Amazon require so many words in these product reviews?

This is a cute little uniform shirt. I ordered Navy. It has a girly fringed collar and is tagless. It has four buttons in the front and is made of a breathable cotton/polyester blend. The short sleeves are also lined in girly fringe. There are no washing instructions included, but I washed them with like colors and tumbled dry. It looks a bit worn after the first wash, so my suggestion would be to wash in like colors and let it line or air dry. You shouldn't need an iron after that.
