    Description 

    Designed to adapt and flex with your changing body, these high-waisted gym leggings will take you from the earliest stages of your pregnancy right through to postnatal life – you’ll get years of wear out of them!

    When you’re pregnant, it can be tempting to try and ‘size up’ in basic leggings and hope they’ll see you through. There are many reasons why this is unlikely to be comfortable or cost-effective for anyone, but if you’re an active mum-to-be, it’s even less likely to be the answer. The last thing you want during a workout or class is annoying seams, a saggy crotch or the dreaded see-through fabric!

    Our specially designed pregnancy sports leggings are cut from squat-proof, sweat-wicking fabric that hugs your bump without ever feeling restrictive – even at 40+ weeks! Light compression gives extra support, helping to ease back pain and combat varicose veins, while the super-high waistband has dropped seams with no pesky stitches to dig into your belly.

    Our redesign of these leggings have won both Platnium and Gold in the Loved By Parents 2026 awards for best maternity brand and best maternity innovation product!

    Our Latched active support leggings have been awarded Silver in the Made for Mums 2023 awards.

    We're also proud to be the GOLD winner in the Best Maternity Fashion Brand category of the Loved By Parents awards 2022 and Latched was awarded 'Best Maternity Activewear' in the 2022 Project Baby awards.

    Our Maternity & Postnatal leggings have also been shortlisted in the 2023 Made for Mums Awards alongside our Oversized Nursing Hoodie.

    Why mamas love them

    Bump-loving fabric
    Our stretchy fabric will grow with your body from the first trimester to the third, without ever compromising on support. It also provides light compression, which can help ease pregnancy back and hip pain, reduce leg swelling and prevent varicose veins.

    Perfect for postpartum life

    You can wear these maternity gym leggings for as long as you like after your baby is born – in fact, they'll probably become your go-to for everything from a high-impact workout to a stroll to the shops! The high-rise waistband will continue to adapt with and gently control your postnatal tummy, giving you a flattering silhouette and boosting your confidence to simply enjoy moving your body.

    Never see-through!
    Squat to your heart’s content without worrying that your leggings are letting you down! Our fabric is completely opaque and will stay that way through wash and wear. It's also the ideal thickness for preventing VPL and concealing maternity pads or knickers. 

    High waistband with dropped seams
    These maternity gym leggings sit extra high at the waist to support your tummy throughout your pregnancy and after you've been through labour. The waistband won’t roll down or need to be pulled up constantly, and the seams are dropped to sit comfortably low on your bump (they're also strategically positioned so they won't aggravate a C-section scar).

    Two large pockets
    It’s a fact: pockets make life easier. Especially mum life! That’s why we’ve added one at either side of our maternity and postnatal leggings. And the best part is, they’re deep enough to easily hold your phone, keys, a muslin or even a baby bottle!

    Sizing

     
    What stage are they for?

    These maternity leggings will see you through the Show, Glow and Grow stages of your pregnancy (check out our Bump Guide below for more guidance on the different stages). Most women find they can wear them to 40+ weeks. You can count on them for comfort and support once your baby is earthside, too, because they're designed to adapt to your changing body both during and after pregnancy. 

    Show
    Generally the first trimester: you're newly pregnant and your regular clothes are becoming a little tight. 

    Glow
    Generally the second trimester: your bump has 'popped' and there's no more squeezing into your jeans with the hairband hack!

    Grow
    Generally the third trimester: you're in the thick of it now! You can't really see your toes anymore and baby is very much at home! 

    Whoa
    Mamas of multiples or those with truly magnificent bumps – especially towards the end of pregnancy. If you're in the 'Whoa' camp, it's likely you'll find our Classic Comfort Maternity Leggings give you a more comfortable fit around your bump.

    Postnatal
    The fourth trimester and beyond: you've got through labour, your baby is here and you're keen to get moving. You need sports leggings you can count on to boost your confidence and support your post-partum tummy through every movement in comfort.
