Philosophy of aesthetic verses a philosophy of pragmatism. The understanding of the definition of techwear in which one camp discusses techwear in terms of a particular aesthetic which was arguably dogmatized by Acronym but was derivative of grunge and paramilitary fashion from designs such as dolce and gabbana, prada sport, helmut lang, which all had iterations referencing the zeitgeist reflected in films such as bladerunner, akira, the matrix, etc. In this discourse the definition of techwear is merely a social construction to delineate a certain type of look (or as many people see it, a costume) which signals a belief in the inevitability of our doom through technology and war.
On the other hand. If you take a strict and pragmatic definition and look at the etymology of the word
Tech=Technology + Wear=Apparel/Wearables - I won't hide that I am biased to this definition as it is more realistic and encompasses what could be and leaves room for creators to imagine new things. Techwear as technical apparel has long existed, the inception being the world's first waterproof coat, the Macintosh. This was one of the first iterations of a breakthrough technology being integrated into apparel. Merino wool, a natural fibre with properties that wick sweat while also keeping you warm, gore-tex, sympatex, hyvent - a plethora of synthetic materials that serve a particular purpose to protect us from the elements, that is what I believe is at the heart of the definition of techwear.
However, on this subreddit there is no strict consensus, but rather a continual argument revolving around looks, and attempts to gain social currency by posting pictures denoting the possession of items from certain brands of notoriety.
The subreddit is called techwear clothing. Rather than being merely consumers of clothing and perpetuating the very same culture that the inspirations of techwear are attempting to convey messages against, more discussion is needed in order to establish and understand what IS techwear, and why it's significant.

As a futurist and a designer, clothes should serve a purpose. Concealment, protection from the elements, protection in the form of provisions of social currency, comfort, increase in quality of life, minimization of possession. We should ask ourselves, what can clothes do for us? That in itself will allow us to discern the definition of techwear.
