This article and equipment list assume that two people hike on medium, non-technical terrain in late summer / early autumn. It has been modified, including some innovations, including tents, sleeping mats, etc.
A backpack is essential, but because we are novices or can't judge the size we want, we often fall into the trap of grabbing a 5000 cubic inch /80-liter backpack and filling it with equipment. Then it's much more difficult to carry that bag.
You may find that the conversation around the tent focuses on two simple questions: "how much is it?" How much does it cost? ' Because of this very narrow way of thinking, useful qualities such as ease of pitching, weatherproof, internal climate, or (especially) available headroom/space are often overlooked
There are dozens of sleeping bags on the market, and there are also many opinions on what is the "best". If I can add my 2 cents: I'm skeptical about the temperature "rating" - ask whether the package has been rated using EN standards. If so, please make sure you understand how this rating system applies to you. Male sleepers should be positioned with a "low" rating, Female sleepers (or male end-users who sleep a little colder) should use the "comfort" rating as a guide. Make sure the bag you are looking for is suitable for you without the insulating material around your compressed knees and feet, and look at details such as drainage tubes and hoods - these are where manufacturers save money, but the warmth will "leak" from sleeping bags Come out. Ensure that both are of sufficient size/shape to maintain that these design defects do not appear in the en rating because the manikin used in the en test does not move - but they do appear in the real world.
Everyone has their preferences - some common elements are layering, a set of "dry" clothes, and a set of "wet" clothes, and make sure you have gloves and an insulated hat to deal with night / sudden weather changes. I'll leave the details to you. But - I would suggest one thing: put your clothes in dry bags. It will keep them dry (obviously), make it easy to pack and unpack your backpack (even if it's raining), and maintain order.
