  We study 1/2 BPS Wilson loops in 3d $\mathcal{N}=4$ $U(N)$ Yang-Mills theory
with one adjoint and $N_f$ fundamental hypermultiplets from the Fermi gas
approach. By numerical fitting, we find the first few worldsheet instanton
corrections to the Wilson loops with winding numbers 1, 2 and 3. We verify that
our Fermi gas results are consistent with the matrix model results in the
planar limit.
