Is it really necessary for a windproof cycling jacket to be both water-resistant and breathable, or are manufacturers just using these features as an excuse to charge more money? Ive seen some jackets on the market that claim to be windproof but still allow for a decent amount of airflow, while others seem to prioritize keeping the elements out at the expense of comfort. Whats the point of a windproof jacket if youre just going to end up sweating buckets underneath it anyway? Are there any real-world benefits to having a jacket thats both windproof and breathable, or is it just a marketing gimmick?
