The twin Higgs mechanism is a mechanism which removes the quadratic sensitivity of the Higgs mass to heavy states if they are symmetric under the twin symmetry.  This requires the addition of a copy of the known particles which are neutral under the standard model symmetries.  In typical models, like composite Higgs and supersymmetry, the new partners to cancel top loops are colored and are becoming more constrained at the LHC, putting tension on naturalness.  In this talk I will discuss an implementation of the twin Higgs mechanism in composite Higgs and show that it can result in natural models without light top partners.
