It’s a fairly simple concept: take painting supplies outside. So you grab a slim bag, little sketchbook, travel brush, and a little thing of paints.

You’re all set.

Except for water. It doesn’t fit, and it could leak.

Ipsy bag, reflextions 3x5 watercolor sketchbook, DaVinci casaneo travel flat brush, and tiny tin which holds 6 half pans
Pictured: the supplies listed above.

These are my favorite water containers for painting outside that haven’t leaked on me, and are fairly small.

Nalgene

This has been my favorite water container for months. Nalgene make drinking water bottles for hiking that are designed not to leak. This is a little 2 oz one. (They also have a larger one, which is much heavier.)

If I had to pick, this would my favorite water container, unless I have a really small bag, then I would use a 1 oz from HumanGear.


HumanGear

Shop cloth, pro-arte prolene travel brush, a Gallo landscape set of 6 half pans in a tiny tin, 4x6 block of watercolor paper, and the 1oz nalgene water container from humangear
I think that is a 4×6 block of paper, and there are 6 half pans in the tin. The brush is the travel flat Prolene Plus from Pro Arte, and that’s the 1 oz HumanGear.

Then I found this little thing. It’s 1 oz, and so tiny. And yes, I’ve painted a whole painting on a little sketchbook with it and a quill. There was no water left by the end.

It works well for fitting into tight spaces in a little bag.

The HumanGear also comes in a bigger size which I love for painting with at home. It works really well with a 3/4 flat, something that is much harder to fit in the 2 oz Nalgene.

If you’re looking for absolutely spill proof, I’d go with the 2 oz Nalgene. The 1 oz HumanGear has shorter sides, and when you’re holding it and painting, if anything startles you, you’re gonna get wet.

If you’re going to do plein air with the HumanGear 1 oz, I would suggest a water bottle to refill it. A cleaned out drink flavor enhancer bottle works really well. (Just be aware some of them are harder to squeeze water out of with wrist strength issues). The idea came from Lindsay Weirich on YouTube. (I loved her Watercolor Landscape class on Teachable if you’re looking to paint landscapes.)

I feel that the Nalgene is safer to literally throw in a bag and not worry about leaking, but that could be because I have more experience with it. The Humangear hasn’t ever leaked on me. I’ve tried a few other brands but they’ve all appeared to leak. The circumstances were suspicious at best.

The larger Nalgene on the left, next to 2 other larger sizes of Humangear. The one on top on the right works the same as the 2 oz Nalgene, but has a wider mouth. I think they’re both 2oz. There’s a plant on the desk in the background.

A Note on Water Brushes

Even though water brushes are technically brushes, I put them in with water containers since that’s their purpose.

They can be hard to use with wrist strength issues, since the way you get water out of them is by squeezing them.

The best ones are Pentel, and ones that say Aquastroke that came with with my Whiskey Painters brand bijou palette. I’ve been able to use both of them.

Make sure you’re using the ones with the larger heads, and that the handle is a bit wider, and that you can squeeze water out of them easily.

Water brushes are probably best for if you’re going to paint in a Dr’s office, instead of an open thing of water.

(Make sure you empty the water out and leave them open to dry if you’re not gonna use them for a while.)

Aquastroke large flat, and a smaller one, next to a sharpie. The large flat is longer than a sharpie so it doesn’t fit in a bag as well, and the other one’s handle is so short it’s hard to use. They’re on a strathmore black watercolor journal.

No one would choose to paint with a water brush in a studio, since regular brushes are way better (water brushes are plasticky bristles, and hard to control the water).

That’s why I choose to take either the HumanGear or the Nalgene water bottle, and use travel brushes. I’ll be talking about travel watercolor brushes in another post.


If I had to choose, my favorite water container for throwing in a travel bag is the Nalgene, unless it needs to be really small to fit in a little bag, then I use the HumanGear 1 oz.

You can get the 2 oz Nalgene on Amazon; not the right photo, but select the 2 oz one.

And the 1 oz HumanGear comes in a set. 🙂
