  1. very pleased Review by Sandy

    I bought two pairs for my son and we are both very happy with them. (Posted on 24/07/2017)

  2. Really Happy Review by El Tee

    Great fit, easily adjustable, my son is very comfortable and happy to wear them. They just about last for one school year- Hem taken up in September and gradually let down till July. Colour fades with washing so hem lines show and not so smart by the end of the year, but I am totally ok with this knowing the product is ethical in all respects and that my son's skin stays eczema free. Only one real issue in that the popper at waistband has come off two pairs so have to stitch them back on periodically. Will continue to buy them- have already got two pairs in sale ready for next September. (Posted on 12/04/2017)

  3. Excellent products Review by Hannah

    Dear eco outfitters,
    My son is in year 2 and I have been buying your excellent grey shorts and trousers since he started school and I,m really pleased with them. They are really soft, a great style on my son and have been so durable.Thank you! (Posted on 09/12/2016)

  4. So happy to find such high quality school trousers Review by Zan

    I too search in vain for 100% cotton school trousers, just how crazy it sounds that these should be hard to find, just normal 100% cotton school trousers. The trousers are outstandingly good quality, my son LOVES them for their comfort, I love them for their look, feel, cut.... everything. Will shortly be ordering more, Many thanks for them (Posted on 19/11/2016)

  5. Lovely trousers Review by Sharlene

    I have to say my sons skin has improved so much already using your products. One day he had to wear his polyester shorts this week and the eczema had broken back out.
    Thanks again (Posted on 20/05/2016)

  6. HUGE thanks Review by Nanette

    I just want to say HUGE thanks for the uniform I ordered, it arrived today and far surpasses the beautiful and soft quality I was expecting... I'm so happy I'm going to look into replacing my high school age son's uniform with organic cotton also... (Posted on 04/01/2016)

  7. Not all great Review by Ellen

    Had these a couple of weeks and the waist popper has come off. Impossible to fit back on, so I've had to rip out the fixing and sew in a press stud. Also, the fit seems on the small side. I have had to order a larger size and shorten the trousers. Other than that, they are nice, soft, and comfortable.

    Reply from EcoOutfitters:
    Dear Ellen,
    Thank you for your review. We are very sorry the popper has come off, could you possibly send us back the faulty pair so we can exchange for a new one, we will reimburse you for the postage cost.
    We sincerely apologise for the inconvenience caused.

    Reply from Ellen:
    Thank you for your kind offer to exchange the trousers, but I feel, having taken up the hems and sewn in the new press stud, that it would be too much trouble to send them back. I would like to reiterate that the trousers are very comfortable and of good quality.

  8. organic cotton trousers at last! Review by Caroline

    Hi Ladies
    On behalf of myself and my 2 little boys I just wanted to say a massive THANK YOU!!
    I have spent the last 4 years neurotically searching unsuccessfully for uniform that is Teflon free, not stain resistant, not easy care, storm-wear... etc etc.. Have contacted retailers & manufacturers asking them why they happy to expose our children to a cocktail of toxic chemicals, so that parents have to wash / iron less!!?! I know we live in a mad world but surely it's obvious that this is wrong even to those blissfully ignorant... I had wearily almost (but not quite!) resigned myself to another year of Trutex trousers that I boil wash 20 times before use... When I thought I'd just check once again in case someone somewhere had seen the light!! And you have... In some style!! GOOD FOR YOU ladies I look forward to making myself a little poorer for a very good cause..Many thanks, and good luck with your business venture, I will spread the word! (Posted on 15/12/2014)

  9. It's great to find some 100% cotton trousers at last! Review by MyItchyBoy

    "It's great to find some 100% cotton trousers at last! The trousers have a really nice feel to them - sturdier than the ones we've had from the high street - which helps with durability. It also helps them keep their shape much better by the end of the school day.

    There is a label in the back of the trousers but in a sensible place and it does include a space for the child’s name.

    The hem is nice and smart, although it does make them a little harder to hem using iron-on tape if they need taking up. The sizing was rather generous but it does say they will shrink slightly after washing. We found that even after that they were still larger for sizing than some places. The adjustable waist tabs are good quality and the gathering at the back is neat even when they are pulled tightly. They wash and iron well and overall are much smarter and look nicer than previous trousers we've tried.

    I've not rated them 'excellent' only because we've not had them for the whole of the school year, so can't comment on the long-term durability. (Posted on 11/08/2014)

Organic cotton is not treated with chemicals to prevent shrinkage so after washing they will shrink by up to 5%. Our garments are cut more generously to allow for this shrinkage. Once washed and dried they will have shrunk to the marked size.

Caring for your garment

Always wash garments before use. Our garments made from tough organic cotton, it gets softer with every wash.

Washing your garments

Garments can be machined washed, please care for environment, wash at 30C. Ensure zips are closed before washing. For best results, wash garments inside out. Wash with ecological or non-biological washing liquids or powders.

Drying and ironing

Line dry your garments for best results and ensure garments are turned inside out when line drying as bright sunlight can fade dark colours. For best results when ironing, iron whilst garment is slightly damp. Placing a cloth over your garment whilst ironing helps reduce sheen.
