Australia took a while to catch up mainly due to the ruggedness of our major walking areas. SW Tasmania is incredibly hard on gear as is a lot of New Zealand
When LW gear got here we adopted very quickly even if it did wear out quickly. We went LW and UL simply by making do with less but you cannot do that in winter so we winter snow campers still had to carry those heavy loads
Most of what I remember is being cold and wet a lot of the time, that doesn’t happen these days, I haven’t been wet & cold at the same time for decades.
This doesn’t mean we deliberately carried heavy packs, we trimmed and cut and always got our loads as light as possible, the mantra has always been “Count every ounce because every ounce counts” the weights were simply a consequence of the affordable materials available to us at the time. Times have changed and now the LW finely woven 3 ounce cottons are the expensive fabrics and 1 ounce ripstop is the cheap stuff
UL gear does have drawbacks where longevity us concerned tho and this can become a serious financial burden, my japara windshirt lasted 3 decades until it became unusable and I go trough a Montane UL windshirt every season because the fabric cannot be sewn strongly enough to withstand the treatment it gets CC skiing DIY seems to be the option there
