Summer · 3 nights · Ultralight

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 30°F of margin below a 50°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-2.8 clears the R-1.5 floor for summer 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.

50 L carries 3 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.

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.

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.

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.
