3-Season · 2 nights · Lightweight

A freestanding tent stands up without perfect stake placement, so a sloppy first pitch still keeps you dry. Experts trade that for a trekking-pole shelter because the poles are already being carried.

20°F rating gives 12°F of margin below a 32°F night. Plan to the comfort rating, not the survival rating, and leave 10°F of margin. Being too warm is fixed by unzipping.

R-4.2 clears the R-3.2 floor for 3-season nights. Cold ground steals more heat than cold air. Bag ratings are tested on an R-5.4 pad — pair a 20°F bag with a thin pad and you do not have a 20°F system.

45 L carries 2 nights of this kit. Buy the pack last and size it to the gear you actually have. Fit matters more than grams on a first pack — a suspension that puts 80% of the load on your hips beats two saved pounds.

Nothing is warm when soaked — "warm when wet" defies physics. If sustained rain is likely, synthetic loses less than down.

"Water-resistant" is not rain gear. Hypothermia is possible above 40°F once you are wet and windblown, which is why the shell is required even in summer.

Grid fleece dries fast and buffers moisture better than a puffy, which keeps the puffy dry for camp.

Sleeping in what you hiked in transfers your sweat into the bag and costs you more warmth than any bag upgrade buys back. One dry set, never hiked in.

Filter everything. Below freezing a filter can be destroyed by ice, so it sleeps in your bag and the chemical backup stops being optional.

Plan about half a litre per hour of hiking, more when hot. Two litres of capacity covers roughly four moderate hours between sources.

Headlamp, not flashlight — you need both hands to pitch a tent in the dark. Shoulder-season nights are 14 hours long.

Your phone is a great map right up until it is cold, wet, or at 3%. A baseplate compass weighs 31 g and has no battery.

An actual kit, not a token one. Blisters end more trips than injuries — tape a hot spot the moment you feel it, not at camp.

The scissors and tweezers are what you actually reach for. A heavy folding camp knife solves problems a 21 g tool and a strip of tape already solve.

Required in every season — snow and altitude reflect more than summer trail does.

Check your park first — many require a hard canister and a hang is not legal there. A canister has no technique to get wrong at dusk.

An all-in-one system means nothing to match and nothing to balance. In the cold a hot drink is a thermoregulation tool, not a luxury — which is why the stove stops being optional.

One bank, one cable, everything on the same connector. Cold cuts lithium capacity by roughly a third, so the bank sleeps in the bag.

A 32 g layer that closes the gap at your collar is the cheapest warmth you will ever carry.

New boots on trip one is how you get blisters on mile three. Break them in on a loaded day hike first.

Wool or synthetic, never cotton. Two pairs up to three nights: one hiking, one that stays dry for sleeping.

Convertible legs cover a 40°F swing without packing a second garment. Cotton is excluded outright.

Aluminium bends where carbon snaps, and costs a third as much. For experts they are also the shelter poles, which makes them free.

620 g per day, the figure a guide measured across 400+ clients. Most people who pack 2 lb/day carry leftovers home.

About half a litre per hour of hiking — 2 L covers roughly four moderate hours between sources.

377 g gross: 230 g of gas plus 147 g of steel you carry the whole trip. Boils roughly 16 L.
