What to know before comparing two products

Short answer: Compare the content declaration, fabric weight and construction. Two products with the same material name can differ widely on all three points, even if they look the same in the picture.

The declaration first

Check whether elastane or synthetic fibers are in the blend before comparing further on price or appearance. This changes feel, fit and care, even with the same main material. See bamboo underwear for men for examples with clear declarations.

The fabric weight

A heavier fabric drapes better and is less see through than a light one, even with the same fiber name on the label. Weight therefore often says more about the actual experience than the fiber name alone. See facts about bamboo for more on what affects fabric weight.

The construction

The width of the waistband, the seam type and whether the edges are laser cut determine much of the difference in lifespan between two otherwise similar products. This is where most quality differences actually arise, and it is rarely visible in a product photo. See bamboo underwear for women for examples of good construction.

The size chart

Always compare measurements in centimeters, not just letters like S, M and L, since sizes vary considerably between brands and manufacturers. A chart with concrete measurements gives a far more reliable picture than letters alone. See guide to briefs and underwear for help measuring correctly.

The care instructions

If one product is only meant for hand washing, it is not really comparable to one that tolerates machine washing, regardless of what the two otherwise cost. An item requiring special care often ends up unused in the closet. See washing and care for what the different symbols mean.

Price in isolation

Price alone says very little about quality when comparing two products without knowing the other factors mentioned above. A more expensive product can easily have worse construction than a cheaper one, if only the material was prioritized.

Pictures can be misleading

Product photos rarely show fabric weight, seam type or waistband construction clearly enough to judge quality from them alone. Always read the product text thoroughly, and look for concrete details rather than relying only on the visual impression from the image.

Reviews as a supplement

Other customers' experiences can give a hint about durability and fit, especially when several mention the same thing. Use them as a supplement to the actual specifications, not as the only source, since experiences can vary greatly from person to person for several reasons.

Take your time comparing

A thorough comparison takes a little longer, but it often pays off through fewer poor purchases and longer durability on what you end up choosing. This is especially worthwhile if you shop regularly across several different brands.
