What to carry, what it should cost, and how to sleep warm in it. Every number here comes from physics, a named standard, or the same catalogue of 313 items the finder ranks — so you can click through and check it.
Choosing your kit
Work out what you need before you spend anything.
How to choose a backpacking kit: the big four, in the right orderTent, bag, pad and pack are one system, not four purchases. Start from the nights you actually sleep out, and buy the pack last.
What size backpack do you need: litres, torso length and fitPacks are sized by torso length, not height. How to measure yours, how litres map to trip length, and how to test a loaded pack before you buy.
How much to spend on a backpacking kitFour purchases, and the split should not be even. Where money earns its keep, where it only buys grams, and three worked budgets.
Sleeping bag temperature ratings: what the number meansWhat an ISO 23537 comfort rating measures, what the lab assumes about your night, and how much margin to leave before you trust the number on the label.
Sleeping pad R-values: the number that decides whether you sleepWhat an ASTM F3340 R-value measures, why the ground takes your heat, how R-values add when you stack pads, and which number suits which night.
Down or synthetic: choosing the fill in your sleeping bagDown wins on warmth for weight and packed size. Synthetic wins wet and cheap. What fill power measures, what treated down fixes, and how to decide.
Choosing a tent: shape, weight, and what waterproof actually meansTunnel, dome or semi-freestanding, what freestanding buys you, what hydrostatic head really measures, and why a second door earns its weight.
Living with it
Packing it, carrying it, sleeping warm in it, and making it last.
Staying warm at night: the pad, the bag and the air between themWarmth is a system, not a bag. Why the pad is usually at fault, why a ventilated tent sleeps warmer, and what to do when you wake up cold.
Packing a backpack so it carriesWhere the heavy things go, what stays reachable in the rain, why a half-empty pack carries worse, and how to put it on so your hips take the load.
Base weight, and cutting weight without losing the tripWhat base weight is, why the big four decide it, and a method for weighing and cutting that does not cost you warmth or shelter.
Looking after your kitStoring a bag uncompressed, drying a tent before its coating fails, washing down, patching a pad, re-proofing, and which jobs to pay for.
