Let's start with a confession: Even with some practice in writing reviews for PG, I often find it difficult to write meaningful tests about soft goods like ski underwear. With bindings or ski boots, you can concentrate on the technical features. Of course, personal taste always plays a role in the evaluation, but there are objective criteria that can be used to compare different products in a meaningful way. For hardshells and outerwear, in addition to personal preferences, there are questions such as: Does the zip work? Does a helmet fit under the hood? Are the pockets well positioned? Does the membrane hold up?
For me, the first question with baselayers is always: does it fit me? Of course, there are also differences in function - merino is less smelly, synthetic fibre dries faster, and so on. But you can't go too far wrong with a vest in terms of function, so it's often a matter of personal preference and fit.
So now a bra test. In my experience, bras must first and foremost fit well. And that naturally depends heavily on the shape of your body. The following test report is therefore very subjective in this respect and should therefore be treated with caution. If there are any readers here who have not yet dealt with this topic in detail, a limping comparison to clarify: A ski boot can have perfect downhill characteristics and a great walking mode, but if the heel slips or a wider forefoot can only be forced into the boot with pain, no matter how great the technical features are - we won't be happy with the boot. It's the same with bras.
