  We investigate several aspects of BPS latitude Wilson loops in gauge theories
in three dimensions with $\mathcal{N}\ge 4$ supersymmetry. We derive a matrix
model for the bosonic latitude Wilson loop in ABJM using supersymmetric
localization, and show how to extend the computation to more general
Chern-Simons-matter theories. We then define latitude type Wilson and vortex
loop operators in theories without Chern-Simons terms, and explore a connection
to the recently derived superalgebra defining local Higgs and Coulomb branch
operators in these theories. Finally, we identify a BPS loop operator dual to
the bosonic latitude Wilson loop which is a novel bound state of Wilson and
vortex loops, defined using a worldvolume supersymmetric quantum mechanics.
