Do Good? Do Better!
Beware!!
I bought a Cotopaxi Teca Windbreaker directly from their site. It's advertised as being suitable for 'windy ridge hikes' and 'breezy bike rides'. First wear of it, I did 5 minutes light walking on a chilly day with just a t-shirt underneath, at the end of which I had to towel myself dry I was so incredibly sweaty.
I contacted Cotopaxi customer support (which appears to be a bot masquerading as a human), who informed me that sweating profusely in the top after a short walk was entirely normal and in line with the jacket's design! They suggested that if I wanted something for active use I should have bought something else. So it's obviously not suitable for moderate exercise of hiking and biking as advertised (and which I mainly bought it for), and risks hypothermia in some weather conditions. Nevertheless, they would not accept a return because it had been worn - somehow I was supposed to be able to work out that it wasn't fit for purpose just by looking at it!
So I am left out of pocket with a windproof sweatbox that is unsuitable for any use. I'm so angry with my experience. I used to like Cotopaxi as a brand, but they appear to have gone massively downhill. I willl never purchase from them again. Judging from other reviews, I'm not the only one.
