I had a different spexcel gilet, seemed fine initially but the zip is shit. After a few rides it wouldn't do up or undo without splitting. Wouldn't recommend it.
I've got a spexcel gabba copy with a similar issue. I can zip it up and pull it over my head, but my gut splits it if I try zipping it up whilst it is on.
anyone got on with the spexcel gilets? https://www.aliexpress.com/store/product/SPEXCEL-2018-All-New-PRO-TEAM-CYCLING-WIND-Vest-Super-Lightweight-cycling-Gilet-easy-to-carry/2219030_32849839196.html?spm=2114.12010615.0.0.190727abnbi34l
