It's a 180€ jacket, the fact you got it luckily for 30€ is relevant only for you.
Yep,right. But it's quality and versatility are worth the full price. I do have wosawe, ykyw, darevie winter jerseys (and northwave), they became almost useless after I got PRO SL3, I do use darevie for very short rides to nearby shop or a post office, others just occupy some place in my wardrobe. The price of all those jerseys together is equal to Endura's full price, but they are useless, so it's enormous Endura's quality/price advantage. Like 100 quality/180€ to 5quality/180€. Same about Endura Singletrack pants vs Rockbros cycling pants
I do use Darevie, ykyw summer jerseys and bibs - they are better and cheaper than Endura's. But for winter clothes I'd better choose western brands. Same about shoes.
