I would never rely on ANY Ali store or brand for ANY sort of technical clothing. Just spend the money once and get a good and tested quality product from a reliable brand.
This sort of comment is antithetical to the entire existence of this forum. Why are you even here?
People here discuss which particular carbon wheelsets and bike frames to buy from Ali express. People send it down mountainsides riding atop stuff they buy from Ali express and come here to discuss whether it's worth risking their life on this brand or this other brand. And you're saying a gilet is too technical to buy from Ali express?
For sure, some clothes from places like Ali express are crap and will lead to the buyer having a bad time. But some are just fine and represent significant savings over many western brands with the same performance (almost all of which is made by some third party factory in china, anyway). The whole point of this website AND THIS PARTICULAR THREAD is trying to share which ones worked and didn't work for us.
For the record, all my winter kit came from Ali express, except for my gloves. And it's all been fine (except for the gloves). Proper western branded winter kit is stupidly expensive. I would actually say, prohibitively expensive. It would be literally too expensive ride in winter with the prices these days, for me. The price to buy 2 pair of winter bibs, jerseys, jackets, gloves, shoe covers, and caps all from reputable US retailers would probably cost more than a Wahoo Kickr Core smart trainer that I could use indoors for the duration of the winter (and every winter after).
