Soto Helix Coffee Maker

The Soto coffee maker is a great little filter holder that folds down small to fit into any handlebar bag or seat bag, and it's light enough that it won't be noticed.

The ingenious design of this filter means that it won't collapse under the weight of water and wet grounds. It is made like a spring, so the default is that it is open. It uses the three base prongs to hold it shut for traveling.

The base pops out to 4.5 inches by 4.1 inches, so it should fit most mugs out there.

Made of stainless steel coil, this 45g filter holder comes with a mesh carrying bag and 10 cone filters. Additional #2 filters can be found at your local grocery store.
