One of the best things about cold therapy on the road is that it needs almost nothing to work. No power, no plumbing, no permanent setup — which makes it one of the few recovery tools that genuinely travels as well as you do, free camp or not.

What you need

A portable tub, cold water, and a bag or two of ice from the last servo you passed. That's it. No chiller required — the Optimal Pod's five layers of insulation are enough to keep water cold for hours on their own.

Setting it up

Fill the tub with the coldest water you have access to — tank water, a nearby tap, or a creek if you're camped near one — then add your ice. Set up somewhere shaded if you can; direct sun will warm the water faster than you'd expect. The whole thing takes about five minutes and packs flat again once you're done, so it's no burden on space in the vehicle.

How long, how cold

Aim for water between 3–10°C and sessions of two to five minutes. You don't need to push past that — the benefit comes from consistency (a couple of short sessions a week), not from how uncomfortable you can make it. Expect the first 30 seconds to be the hard part; most people report feeling sharp and clear-headed within a minute of stepping out.

Keeping the water usable

Without a chiller, plan to change the water roughly every two weeks of regular use. If you're moving camps frequently, that's usually a non-issue — you'll often be refilling anyway.

Getting started

If you're deciding whether a no-power setup is right for your trip, this is really the simplest entry point into cold therapy there is. [See the Optimal Pod →]
