Magnetic reconnection at the magnetopause and magnetotail affect many magnetospheric dynamics including the onset of magnetospheric sub-storms and space weather effects, and the balance of energy in the magnetosphere. In these environments, however, asymmetric boundary conditions and imprecise knowledge of the motion of reconnection exhausts relative to spacecraft affect the extent to which we can observationally study reconnection in these environments. Solar wind reconnection exhausts, however, frequently form large- scale structures which propagate past spacecraft in a regular manner. This makes the solar wind an excellent environment in which to study basic reconnection physics. In this study we have identified multiple solar wind reconnection exhausts in the Cluster data set and further analysed an existing data set from Wind. With Cluster and Wind we analyse these exhausts with high cadence measurements. These high cadence measurements reveal further magnetic structure across the exhaust than can be seen with lower cadence measurements, and show several types of qualitatively distinct magnetic field profiles within the data set. Furthermore, we investigate asymmetries of the magnetic field profiles, and the structure of the boundaries of bifurcated reconnection exhausts.
