Swift Maternity & Postnatal Leggings - Jet Black


Need some help? Find your fit.

Our new full length Swift leggings are the latest addition to our collection and if you are someone that loves running, HIIT or any other more vigorous workouts, these are the leggings for you!

The slight sheen on the sweat-wicking, four-way stretch fabric makes these a stylish addition to your wardrobe. With a unique silicone ‘grip’ on the inside of the waistband, you can position the band where you want it and it will stay put, whether you are working out with a full-term bump or postnatally.

Designed with our signature dropped waistband, the fabric gives support to both pregnant and postnatal tummies, the design being particularly good post c-section where the seams won’t irritate your scar. And of course, the leggings have deep pockets on both sides.

Key features:

  • Full length
  • Sweat wicking, four-way stretch fabric
  • Supportive waist band
  • Internal silicone grip on the band to ensure they stay put
  • Pockets on both sides

Our pregnant model is 33 weeks pregnant and wearing size 10

It can be tricky to know what size to get when your shape is constantly changing. We want to ensure you get a perfect fit every time so have created this handy size guide to help you get it right.

Measuring bra size

If you are not sure what bra size you currently are, grab a tape measure and check out Boob or Bust who have a handy calculator, calibrated to take pregnancy and breastfeeding in to account.

This chart calculates in line with the Boob or Bust size guides rather than the bra size you wear. This is because bra sizes vary hugely between brands and we want to ensure you get the best fit every time.  At the very least we recommend choosing the size that corresponds with your under bust measurement in inches - not your bra size! 

We always recommend choosing your pre-pregnancy size for the best fit during and after pregnancy. If you are already pregnant and finding bras too tight, we'd typically suggest picking one size below your current under bust measurement and using the bra extender to the end of your pregnancy (for the best postnatal fit). 

Still not sure? Drop us an email on help@natalactive.com with your measurements and current bra size and we will get back to you as soon as we can!

Great fit

Im a size 10 and ordered a M
Its fits perfectly
The material is on par with sweaty betty and lululemon

Very impressed

So nice to have leggings that down slip down!!

I wasn’t sure about the waistband at first but it is just so nice to have leggings that actually stay in place. I do have to play around with how to place it a bit but maybe that’s because my bump isn’t big enough yet. All of my maternity trousers slip down throughout the day! The pockets are a nice addition and they’re comfy.

Great leggings, but not for running

These are good, supportive leggings that I've taken to wearing every day. I ordered the Luxe too for comparison and quickly decided these were what I was looking for due being that bit tighter and more secure. I don't mind that they are a shinier fabric. I love the non-slip band at the top and the handy pocket on the side. However, I sadly haven't found them quite supportive enough under my bump for running. I feel like I need them to be tighter around the hips and give more lift to reduce the bounce. My pre-pregnancy size gave the best fit, even though I've gained quite a lot of weight and fat!!

my first pair of maternity leggings

I'm from Mexico and I discovered Natal Active through instagram reels…So I gave them a try because I'm a figure skating coach and I wear leggings all the time. I've been using them for a week and I'm delighted with them. Love the fabric and the pockets. I will buy another pair or maybe two

Really wanted to love these

I saw lots of positive reviews on these, but they just aren't for me. I dont think my body shape is quite right for them, i have small hips and a larger bum/legs. I also don't love the material, just isn't as comfy as my other align leggings unfortunately. Nothing wrong with these at all, just personal preference with how they look and feel on me.

Hi Ellie, thanks for your feedback - with regards to the material, these are a very different to the Lulu Align fabric - if you are looking for something similar I highly recommend you try the Luxe leggings which are very similar (and also a different cut which you may find suits your shape better if these weren't quite right!)
