Primark Form product details: decoded

Across our four key activewear ranges (Seamfree, Buttery Soft™, Smooth Support and Running), these are the key design and fabric callouts you need to know to match them to your week of workouts. 

  • Four-way stretch: designed to support unrestricted movement by stretching both horizontally and vertically, retaining its shape after being pulled in multiple directions. 

  • Sweat-wicking: designed to keep you dry and comfortable by drawing moisture away from the skin, supporting quicker evaporation.  

  • Breathable: designed to keep you cool and support body-temperature regulation through improved airflow.

  • Shower-resistant: found across our running range, pieces with this label callout have been designed to protect against light rain.

  • Sculpting: seen across Primark Form, from jackets and vest tops to flared and full-length leggings, these pieces are designed with targeted compression to deliver a flattering yet supportive fit.

  • Reflective: another key design detail across pieces in our running pieces, enhancing visibility in low-light conditions.

For low- to medium-impact movement

If workouts were trends, Pilates and yoga would be surging. Whether it’s hot, mat or reformer classes, we know that you need yoga and Pilates outfits that feel and fit as good as they look. Here’s where our Buttery Soft™ and seamfree ranges shine. High-waisted leggings, flares and shorts, and jackets and short-sleeve tops that skim and hug you as you stretch, bend and balance. Looking for versatile support? Choose from our seamfree adjustable-strap crop top options.

Choose your fabric:

  • Buttery Soft™: balances aesthetic and function with ease. Best for medium-intensity workouts, designed with a supersoft, sleek hand-feel fabric.

  • Seamfree: for low-intensity workouts and walking.

  • Both ranges are designed with breathable, sweat-wicking and four-way stretch fabrics.

Training mode: on

Our Smooth Support pieces were created for training, with sweat-wicking, four-way stretch fabrics that keep things comfortable as the workouts intensify. But supportive doesn’t mean sacrificing sought-after silhouettes. From multi-strap cross-back sports bras, V-neck vests and zip-through figure-defining jackets to flared leggings, full-length leggings and 7/8 styles, when it comes to outperforming expectations, you lead on the PBs; we’ll stick to products and prices.

Taking your gymwear outdoors

For runners, outdoor workouts are part of the routine, whether it’s an easy, interval or long run. The good news? Primark Form’s running range is innovatively designed from head to toe to support every mile.

Start with the running vest, a must-have in your rotation. It features side-release buckle fastenings, front pouches for water and gels and a zip-front pocket to securely store your phone, keys and headphones while you're racking up those kms. Need an extra layer? The shower-resistant running jacket comes with a hood and zip-through design to help keep you comfortable when the weather turns. Complete the look with our shower-resistant running shorts. Created with a double-layer construction, elasticated waistband and a back zip pocket for your phone, they're perfect for hands-free running when you don't need the vest.

Made with shock-absorbing technology to minimise impact on your joints during hard-surface runs, and a flexible fit and foam outsole, these pairs are ready to go the distance. Priced at just £15.
