MDUK Chain Reaction Leggings

Please ensure you check your sizing as the leggings/capris may differ between the products.
If you are in any doubt please feel free to contact us for advice.

If in doubt always size up for a more comfortable fit, the drawstring will allow you to tie the waist in.

We strongly recommend adhering to our size charts and wearing the size recommended for your size. The recommendations are in place to ensure you get the most wear out of your leggings/capris. Yes you will be able to fit in smaller sizes but putting the fabric and stitching under strain will only result in your leggings/capris wearing out quicker.

Please order the size listed in the size chart, this will ensure the fabric does not over stretch ensuring they remain squat proof. It also makes sure the pattern looks vibrant (and not faded because the white is showing through).
Finally it stops the stitching  popping or being put under strain.

The leggings and tops are a unisex fit and designed to be worn by either sex. For men's measurements please follow the waist and chest measurements to get your correct fit.
 

Size Guide for Leggings, Capris & Shorts

The leggings and capris are a standard fit and run true to size.

The running shorts are a tight compression fit, there is no need to size up but they will feel tighter than the leggings as they are designed this way.

The loose fit shorts are a looser fit around the thighs, there is no need to size up. These sit lower on the hips and will feel bigger. If you are between sizes it may be best to size down rather than up.

Please check item descriptions carefully as there are differences in sizing between models due to stretch in fabric. 

For men's sizing please follow the waist measurements to get the size required.

Size Guide for Racer Back Bras

Please note that these are a light to medium support and we recommend a more structured sports bra underneath for ladies with a fuller bust that require extra support for higher impact workouts.

I am between sizes on your size chart what size shall I order?

If in doubt size up to the next size unless otherwise stated, never size down if you want the most comfortable fit.

I have a small waist and curvier legs and bum what size should I choose?

Choose a larger size that will allow you the most comfortable fit on the legs and bum area as you can always pull the waist in with the drawstring to allow maximum comfort and fit and prevent any strain on stitching and material. The Skorts have a leg gripper so please be mindful of your body shape to ensure the optimum fit and performance.
