Australia doesn’t agree on much - but when it comes to underwear, the data is clear.
After more than 50,000 verified customer reviews, five pairs of Step One underwear consistently rise to the top for comfort, breathability and all-day performance.
Fit - Look for underwear that stays in place without riding up or bunching. A well-designed fit should move naturally with your body and provide consistent support throughout the day.
Material - Fabric choice has a major impact on comfort. Bamboo viscose blends are ideal for everyday wear, offering a softer, smoother feel than traditional cotton while remaining breathable and flexible.
Comfort - Comfort comes down to the details. Soft-touch fabrics, smooth seams, and waistbands that don’t dig in help create underwear you forget you’re wearing.
Breathability - Breathable materials help regulate temperature and manage moisture. Natural fibres like bamboo viscose promote airflow, keeping you cooler and fresher for longer.
Size - The right size should feel secure without feeling tight or restrictive. Stretch-rich fabrics provide a more adaptable fit across different body shapes.
Durability - Quality underwear should hold its shape and softness wash after wash. Strong stitching and resilient fabrics help prevent stretching, sagging, and early wear.
Our rankings are based on a combination of customer feedback, repeat purchases, and overall popularity across our range. We’ve prioritised styles that consistently deliver comfort, fit, and everyday performance.

Bamboo viscose is softer, more breathable, and better at managing moisture than traditional cotton. It also stretches more comfortably and feels smoother against the skin, making it ideal for all-day wear.
Ride-up usually comes from poor fit or low-quality fabric that loses shape. Underwear designed with longer leg coverage and flexible, supportive fabric helps keep everything in place.
No. Moisture-wicking fabrics are beneficial for everyday wear, especially in warm climates or during long days. They help reduce sweat build-up and improve overall comfort.
Underwear should feel supportive without digging in or leaving marks. Stretch-rich fabrics allow for a secure fit while still adapting to your body’s movement.
High-quality underwear should maintain its shape, elasticity, and comfort after many washes. Durable fabrics and strong stitching significantly extend lifespan.
Yes. Breathability isn’t just about staying cool - it also helps regulate temperature and manage moisture year-round, improving comfort in all conditions.
