    Women's Clothing Size Guide

    Measuring tips

    Take your actual body measurements as they are more accurate than measuring over your clothes or shoes.

    Collar: Measure around the base of the neck where the collar sits.

    Chest: Measure the chest at the fullest part, placing the tape close up under the arms.

    Waist: Measure the natural waistline.

    Inside Leg: Measure from the crotch to where your trouser is normally worn on the shoe.

    Jacket Length: Measure from the centre back of your neck to your hemline. Then length measurement will vary depending on the style.

    Feet: Use a ruler or tape measure to measure your foot (from the heel to the tip of your longest toe) Be sure to measure both feet. Many people have feet of different sizes. Fit to the larger of the two.

    a necessity

    if you live in the UK, you basically live in rain gear. Nothing works better to keep your jacket in top condition than this stuff. I use this with the TX Direct, and my rain gear lasts for years.

    Many uses for this

    Used to wash and waterproof our tent on recommendation from store staff as run out of tent cleaner. Did a great job and lots left over to also use for waterproofing clothes too

    Nikwax Tech wash

    Fantastic stuff to wash you base layers in. Keeps them so that the sweat is expelled & not stuck to your body.

    Love my Paramo gear and this is the only product I trust to wash and proof my jacket, shirt etc - and a good price at Go Outdoors

    Easy to use

    Very easy to use, jacket, trousers and other waterproof gear comes up like new. Zips and fastenings all work smoothly again after use.

    The classic

    Best thing for the job. I am always surprised how just a wash restores the performance of my waterproofs. Great price.

    Good Product

    Used in conjunction with TX Direct on a technical ski jacket to revive waterproofing. Works well when instructions are carefully followed.

    Great product

    I work outdoors, and I bought this to wash and re-waterproof my jacket and over trousers. They came out looking new, and were completely waterproof again. Will definitely be buying more of this. Really easy to use.

    Excellent product

    Used to rejuvenate an old jacket. Add a cap full to the washing machine, press start and 30mins later lovely clean jacket that has regained some of its waterproofing and looks like new. Also bought the spray on to complete the job. Will use again.

    Used with tx wash-in, old paramo jacket is back to being like new

    I have been using this product for a couple of years to clean my waterproofs.
    It does what it says on the tin. I only had issue with one of the many bottles I bought over time. It seemed to have clumped material at the bottom of the bottle and my waterproofs smelt of soap. However, it could have just been a "not so great batch".
    I still buy it, and will continue to.

    Used Techwash on my Berghaus Hydroshell Elite coat and followed by TX Direct, it was 100% waterproof again. Much relief as coats aren't cheap.

    Really worked!

    Used with TX Direct, and just put my anorak in the washing machine and dried outdoors. On the Medway it was totally waterproof, water just beaded up and rolled off. Good products.
