Buying branded underwear might seem straightforward, but an attractive logo or a bargain multi-pack doesn't tell you everything. A poor fit can pinch, a fabric that's too slippery can shift, and an unclear size guide can make returns more complicated. So whether you're looking for men's underwear, women's underwear or sports underwear, it's worth comparing the practical features first.
A well-known brand doesn't automatically guarantee the right fit. Calvin Klein underwear, FILA thong, GANT trunks and sports models from Under Armour each have a different cut and choice of materials. So always compare the composition, waist height, leg length and sizing rather than just the logo or the offer.
A 3-pack of thongs can be handy for wearing under fitted clothing, while men's boxers or men's trunks offer more coverage for everyday wear. A multi-pack is only good value if the style and colours suit your wardrobe. Three pairs you rarely wear won't give you much practical benefit.
Sizes vary between brands and sometimes even between models. A size L from one brand can fit differently to a size L from another. For plus size underwear, check the waist or hip measurement in particular, and see whether the style is described as fitted, slim, relaxed or compression fit.
Cotton underwear generally feels soft and is often chosen for everyday wear. Elastane provides stretch and helps the garment fit better. Look at the exact ratio:
A higher percentage of elastane doesn't automatically mean more comfort. The style also needs to fit well without being too tight. For warmer days, a breathable cotton blend can be pleasant; for intense activity, a synthetic, quick-drying fabric is often offered.
The main styles each have their own purpose:
Pay attention to details such as a wide waistband, flat seams and the position of the leg openings. A logo elastic can look smart, but check that the band isn't too stiff. With a compression fit, such as some Under Armour models, going up a size might make sense if you prefer less pressure.
White underwear is versatile, but can discolour more quickly if washed incorrectly. Wash white and coloured items according to the care label and don't use bleach if it's not recommended. The care instructions vary for the products discussed: some models can be tumble dried on a low setting, while others are not suitable for tumble drying.
Always check:
Careful handling helps preserve the fit and elasticity for longer, but the actual lifespan also depends on how often you wear it, your washing routine and the fabric.

That depends on how often you wear it, the fabric and how you wash it. Replace an item when the elastic band loses its tension, seams come loose, the fabric becomes thin or the fit is no longer right. A multi-pack can help you rotate items and wash them less frequently.
Cotton is often chosen for its soft feel and breathable properties. But do check whether the product is a cotton blend and how much elastane has been added. For sport or intense activity, a synthetic fabric with stretch can be more practical. Always follow the care label to minimise shrinkage and loss of elasticity.
Measure your waist or hips at the point indicated in the size guide. Compare your measurement with the product page and pay attention to the fit. With a tight sports style, the sizing can feel different to a relaxed trunk style. Don't automatically choose a larger size: a garment that's too loose can shift, while one that's too small can feel uncomfortable.
