The short version: water, distance, balls and a dry grip cover most of what a bag is for. Everything after that is comfort, and comfort over four hours is worth more than it sounds. The twelve below are ordered by how much each one changes your round against how little it asks you to carry, and all of it fits in a stand bag.
We make golf nutrition, which is item five on a list of twelve. That is about the right weight to give it.
Water, and more than you think
The thing most likely to be under-packed and the one with the clearest effect on the back nine. A round on foot in summer heat is three to four hours of continuous low-grade effort. An insulated bottle you refill at the turn beats buying a cold drink you then carry warm.
Skip: the single 500ml bottle. It is gone by the fifth.
A rangefinder or a GPS watch
The one piece of kit that reliably takes strokes off an average player, because most bad approach shots are the wrong club rather than a bad swing. Either format works and the watch is harder to leave behind.
Skip: the premium slope model if you never play competitively.
More tees and balls than feels sensible
Both are weightless and both ruin a round when you run out. Six balls is the floor if you are anywhere near water.
Skip: nothing. This is the cheapest insurance in the bag.
A dry towel and a wet one
Two towels, one damp for the clubface and one dry for your hands and grips. The single-towel setup fails on the first humid day, and grip slip costs more shots than it should.
Skip: the novelty microfibre with the logo. Any towel works.
Food that survives the bag
Three to four hours is long enough to run low, and the turn is not always open. The requirement is specific: it has to survive heat and being sat on, and it has to be edible one-handed while walking. Nuts, fruit, jerky and bars all qualify. Ours are the 1st Tee bars and jerky, but a banana and a handful of almonds do the job.
Skip: chocolate in summer, and anything needing two hands.
A glove, plus a spare in a bag
Gloves die from sweat, not wear. A second one kept sealed in a sandwich bag means the back nine is played with a glove that still grips.
Skip: playing on with a glove that has gone slick.
Sunscreen you will actually reapply
Four hours of direct exposure, roughly 100 times a year for a regular player. A stick format gets reapplied at the turn, a bottle gets forgotten.
Skip: applying once in the car park and considering it handled.
A ball marker and a pitch repair tool
Tiny, free at most clubs, and the two things that make you look like you know what you are doing. Repairing your pitch mark is also the one piece of etiquette everyone notices.
Skip: the bottle-opener combo tool. It is heavier and worse at both.
Rain gear, even in a dry month
A packable jacket and a bag hood weigh almost nothing and are useless in the boot of the car. The forecast is wrong often enough to matter.
Skip: the full waterproof trouser set unless you play through winter.
A small first aid kit
Plasters, blister tape and painkillers. Blisters are the common one and they end rounds.
Skip: anything larger than will fit in a pocket of the bag.
A pencil and a spare scorecard
Still the fastest way to keep score, and it works when the phone does not.
Skip: nothing. It weighs nothing.
A phone battery pack
Only if you use a GPS app for distances. The app that is tracking your round is also draining the thing you would call someone with.
Skip: it entirely if you carry a rangefinder.
What to leave at home
- The fourteenth club you never hit. If it has not come out of the bag in five rounds it is weight.
- A full set of head covers on irons. They slow you down at every shot and protect against nothing.
- Three gloves in open air. Two is the answer, and the spare belongs in a sealed bag.
- Anything glass. It will break, and on most courses it is against the rules anyway.
If you pack nothing else, pack more water than you think and a way of knowing the distance. Those two change more rounds than the other ten combined.
Everything after that is comfort, and over four hours comfort is worth more than it sounds.
