>>367771>Yes, all GoreTex material made by W.L. Gore and Associates Company, is GoreTex.Hahaha, sure thing. They sure put their stickers on it, but they don't produce all of it. There are several manufacturers, and they don't all produce the same thing.
If you ever make some of your own stuff and end up buying fabric, you might be surprised to see there's a wide range of Goretex available, with different names of course, but with different capabilities too. Sure, your parka is fine, and mine too actually, I am by no means saying Goretex is shit, it's great! But not all Goretex fabrics are equal, and the cheaper the product, the worse the Goretex. That bivy OP posted certainly isn't the good kind, and it apparenly has Goretex at the bottom, hence my comment on it.
Also bivys are only good in snow and on rocks. Otherwise, don't think they're "better than a tent", just read what I told you above:
>>367764>A bivy is a poorly built tent made of very waterproof material, without a structure and that doesn't need to be pitched.There's nothing more to it, don't think there's some other difference between the two, and bivys have been around for as long as people have slept in unpitched tents, which is a long time. So bivys are heavier, because their fabric needs to be much more waterproof seeing as they don't evacuate water properly, and they're very small, you don't even have enough room to change your socks: how is this better?
When it comes to weight, something like pic related which weights around 150g which you can make yourself for $15, along with a ponchotarp that weights 300g, and about 30g of tent pegs, you have a an incredible tarp shelter at 480g, that's 17 ounces to you. You could have a hammock with a bug net for about the same weight, and actually not much more money if you do it yourself.
I really fail to see how bivys are fundamentally better. I've been "extreme backpacking" if you can call it that, and I found nothing lighter than tarps and hammocks.
