Streamer Thermo Bag 3.0 L

The Deuter Streamer Thermo Bag 3.0 L is an insulated sleeve that wraps a 3 litre hydration bladder, made from recycled 210D polyamide with an insulated lining. It turns warm bladder water into something you actually want to drink.

Who it's for

Walkers and riders who carry a bladder through an Australian summer, where water in a pack can heat up fast on an exposed ridge; and ski tourers and winter walkers in the Snowy Mountains who want it to stay drinkable rather than icy.

Capacity and fit

Sized for a 3.0 L bladder, it measures 44 x 24 x 2 cm flat. Slide the full bladder in, route the tube out through the top, and drop the sleeve into your pack's hydration compartment. If your pack is short on room inside, strap it to the outside instead.

Drinking and refilling

The sleeve opens at the top, so you lift the bladder out to refill it and slide it back in without unthreading anything from the pack. The drink tube runs out of the sleeve as normal, and you drink exactly as you would without it.

Looking after it

The fabric is finished without intentionally added PFAS. Take the bladder out after each trip and let both dry fully, apart, so the sleeve does not trap moisture against the bladder.
