What is the difference between the Chaco...
What is the difference between the Chaco Yampa and Chaco Unaweep?
Primarily, the Yampa has a lower-profile, lighter-weight outsole, and has a totally vegan construction. It is a new model.
The Yampa outsole is a lighter outsole more similar to the old Colorado outsole. Probably a better option for water-based/ Casual usage. It reduces the weight by 20% over the Unaweep, and it is lower profile and less chunky looking. If you are someone who does some serious Hiking in your Chaco's Then you would want to go with the Unaweep, better traction.
