The possibly unbiased selection process in surveys of the Sunyaev Zel'dovicheffect can unveil new populations of galaxy clusters. We performed a weaklensing analysis of the PSZ2LenS sample, i.e. the PSZ2 galaxy clusters detectedby the Planck mission in the sky portion covered by the lensing surveysCFHTLenS and RCSLenS. PSZ2LenS consists of 35 clusters and it is astatistically complete and homogeneous subsample of the PSZ2 catalogue. ThePlanck selected clusters appear to be unbiased tracers of the massive end ofthe cosmological haloes. The mass concentration relation of the sample is inexcellent agreement with predictions from the Lambda cold dark matter model.The stacked lensing signal is detected at 14 sigma significance over the radialrange 0.1<R<3.2 Mpc/h, and is well described by the cuspy dark halo modelspredicted by numerical simulations. We confirmed that Planck estimated massesare biased low by b_SZ= 27+-11(stat)+-8(sys) per cent with respect to weaklensing masses. The bias is higher for the cosmological subsample, b_SZ=40+-14+-(stat)+-8(sys) per cent.
