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.

Good for reproofing and DWR

I mainly Tech Wash to clean and restore waterproofing to my Paramo gear, I also use it for other waterproof/DWR coated clothing. Easy to use either by hand wash or machine.

Keeps everything tip top

I use this to keep all my outdoor clothing clean and fresh. It looks after the waterproofs. Doesn’t clog up the breathability. It’s a doddle to use.
It leaves clothes smelling mildly soapy but I prefer that to the floral assault of standard detergents.

Nickwax Tech Wash

Very happy with its performance, does what it says on the bottle. Wouldn't mind an even bigger bottle, as I wear my gear on a daily basis for work, therefore having to wash more often.
