Five items that cover the practical gap between painting at home and painting on location, chosen to work for a beginner's first outdoor session and a practised painter's regular kit.
At a glance
A pan set in a tin is more practical than tubes. Half-pans travel cleanly, reactivate easily, and save you from carrying a separate palette.
Carry one capped travel round and one water-brush. The travel round protects its point in a bag, while the water-brush covers convenience work and light sketching.
A block is the easiest paper format for outdoor work. It stays flatter than a loose pad, removes the need for a board, and is easier to manage in wind.
Solve the water problem separately from the brush problem. A collapsible cup and a small bottle of clean water are still more practical than relying on a brush reservoir alone.
The small accessories are what stop a session unravelling. Pencil, clips, and a cloth weigh almost nothing but fix the problems most painters only notice after leaving home.
A good kit for painting on location does one thing a studio setup does not: it removes the reasons not to go. The paints stay ready. The paper holds flat without a board. The brushes survive a bag. None of that happens automatically, and the difference between a kit that works and one that frustrates comes down to a handful of specific decisions rather than how much you spend.
Painting away from home removes all the easy corrections. You cannot squeeze more paint, fetch another brush, or tape a buckling sheet down once you are already outside. The kit has to be self-contained, robust enough to travel in a bag, and light enough that carrying it does not become a reason to leave it behind.
The question is not what the ideal kit might contain. It is what the minimum capable kit looks like. Everything below earns its place by solving a specific problem that location painting creates. Anything not on the list can wait until you know you need it.
For an overview of the wider materials involved in watercolour painting, the guides on this site cover paper, paints, and brushes in more detail.
A pan set with built-in mixing space
Half-pans are more practical for travel than tubes. They are self-contained, do not require a separate surface to squeeze paint onto, and reactivate reliably with a damp brush. A tin with at least a small folding mixing area built in removes the need for a separate palette entirely, which is one less item to carry and one less thing to leave on a wall and walk away from.
The number of colours matters less than their quality and how well the selection works together. Six well-chosen pigments produce more coherent work on location than eighteen mediocre ones. More colours usually add more decisions at the exact moment when you want to be looking at the subject rather than the palette.
A travel kit is at its best when it reduces setup. Pre-filled half-pans do that. They let you arrive, wet the brush, and begin. Tubes make better sense in the studio, where space and cleanup are not part of the decision.
A travel brush that holds its point
A brush that loses its point in a bag is not a travel brush. It is an inconvenience that turns up at the worst moment. A capped travel round in roughly size 6 to 10 covers the majority of location work. The cap protects the hairs in transit, and the size handles most washes and detail without demanding a second full-length brush.
A water-brush is a useful addition, not a substitute. It removes the need for a separate water container when wetting the brush between mixes, which matters when you are working somewhere with limited access to clean water. What it does not do is replace a proper round when you need a clean, controlled point for edges or fine work.
Da Vinci and Escoda both make practical capped rounds that are easy to source from UK watercolour suppliers. Pentel Aquash and Kuretake Zig remain dependable choices when you want a water-brush that simply works.
Most advice about travel watercolour kits focuses on what to add. The more useful question is what to leave behind.
Paper in a format that works flat without a board
For location work, a block is more practical than a loose pad. Sheets come pre-stretched and are held in place by the glued edges, which means no clipping, no taping, and no need to carry a board. When a sheet is finished, it stays on the block until it is dry and then comes away cleanly.
Size matters outdoors. A5 to A4 is the most manageable range, large enough to work comfortably and small enough to hold or rest on a knee without needing a surface. Weight should be 300gsm minimum. Lighter paper will buckle even within a block if you are working wet.
Surface is a matter of preference, but cold press is the most versatile starting point. It handles both wet and dry techniques and gives enough texture to feel like watercolour paper without making controlled work unnecessarily awkward on location.
A water container that does not leak
Collapsible silicone cups are the most practical option for outdoor work. They pack flat, weigh almost nothing, and hold enough water for a normal session. A small screw-top bottle solves the separate problem of carrying clean water to places without a tap.
Some painters carry two containers, one for clean water and one for rinsing. That is worth considering for longer sessions where muddy water starts to affect your mixes. What matters is that the water problem is solved cleanly before you leave home.
A water-brush reservoir is not a substitute for either of these. It is a convenience tool, not a complete water system.
A small accessories roll for the things most painters forget
The accessories are unglamorous and genuinely necessary. A mechanical pencil for underdrawing, an eraser, a couple of clips or a little masking tape if you are not using a block, and a small microfibre cloth or paper towel for lifting colour and managing wet brushes.
None of these items attracts much attention in travel-kit lists. All of them create problems when absent. They add almost nothing to the weight of a bag but routinely prevent the kind of avoidable issue that cuts a session short.
What you can leave behind is the studio habit of keeping options nearby. A brush roll with twelve choices, a full palette of colours, and several paper sizes will not improve the painting. They will usually make you less likely to go in the first place.
What to buy
Winsor & Newton
Professional Watercolour Half-Pan Set
A practical first paint set for location work because the mixing area is built in and the pan format removes mess.
Schmincke
Horadam Travel Tin
The stronger option for painters who want artist-grade pigment from the start without carrying tubes.
Escoda
Capped Travel Round, Size 8
A protected point matters more than extra brush variety when the kit has to travel in a bag.
Arches
A5 or A4 300gsm Cold Press Block
A block is the easiest outdoor paper format because it removes the need for a separate board and keeps the sheet flatter.
Pentel
Aquash Water Brush
Useful as a second brush for convenience work, but better paired with a proper capped round than used on its own.
Where to buy
The practical verdict
A workable location kit is a pan set with built-in mixing space, one capped travel round and one water-brush, a 300gsm block in A5 or A4, a collapsible cup and a small water bottle, and an accessories roll with a pencil, eraser, clips, and a cloth.
That is five decisions, each with a clear practical answer. The rest is weight. What changes with experience is not the list so much as how confidently each choice gets made before leaving the house.
