Best flared matching gym set

Fashion is quickly finding its place within the activewear space, because trends aren’t just reserved for day-to-day wear. A prime example? The flared yoga legging. Combining an iconic ‘70s trouser silhouette with the comfort and flexibility of activewear, there’s a reason that the line is blurred when it comes to when and where people are sporting them. Team with the cropped tees, vest tops, sports bras from the range, or similar styles from your daily wardrobe

The key to A/W activewear is all in the layering, and our lightweight sports jackets are a staple for runners of all abilities. Their quarter zip design is great for temperature regulation, the large front pocket for storing electronics during a hands-free run, and the drawstring hem is ideal for cinching or loosening for your desired coverage. Lastly, it’s compact enough that it can be stuffed into your running vest mid-run or rolled up and put into your tote bag during any unseasonably warm matcha dates!

What to look for when choosing women’s gym sets

Selecting the right gym set can enhance your performance, comfort, and style during workouts. Here's a guide to help you find the perfect one:

1. Comfort and fit

  • Snug but not restrictive: Look for gym sets that offer a fitted silhouette without digging into your skin.

  • High-waisted leggings: Provide support, stay in place during movements and enhance confidence.

  • Adjustable features: Tops with adjustable straps or bras with customisable closures allow for a more personalised fit.

2. Fabric quality

  • Moisture-wicking materials: Fabrics like modal, nylon, or spandex keep sweat away from the skin, making sure you stay dry.

  • Four-way stretch: Enables flexibility for dynamic movements like squats, lunges, or yoga poses.

  • Breathable and lightweight: Mesh panels or perforated fabrics enhance airflow.

3. Support

  • Built-in sports bras: A top with built-in support is ideal for low to medium-impact workouts.

  • Seamless designs: Reduce chafing and provide a second-skin feel for activities like running or high-intensity training.

4. Style and versatility

  • Matching sets: Create a cohesive, polished look while offering versatility to mix and match with other workout pieces.

  • Variety of styles: Options like crop tops, vest tops, or long-sleeve tops ensure there’s a set for every preference and activity.

  • Trendy colours or patterns: Choose designs that match your personal style to keep you motivated.

5. Durability

  • Stretch retention: Ensure the fabric doesn’t lose its shape after multiple washes or intense stretching.

  • Opaque materials: Avoid see-through leggings by checking for squat-proof fabrics.

6. Activity-specific features

  • High-impact workouts: Opt for compression fabrics and high-support bras.

  • Yoga or Pilates: Look for softer, stretchy fabrics with minimal seams for ease of movement.

  • Outdoor training: Consider sets with moisture-wicking features for comfort in various conditions.

7. Practical features

  • Pockets: Leggings or shorts with side or hidden pockets for essentials like keys or cards.

  • Flatlock seams: Prevent irritation and chafing.

  • Quick drying: Essential for those who need to transition quickly post-workout.
