We present calculations of hadron production from gluon dominated non-equilibrium matter in various small collision systems using the IP-Glasma model combined with a state-of-the-art fragmentation prescription based on the Lund model. We study bulk observables such as particle spectra, nuclear modification factors (R_{pA}), proton-to-pion ratios and multi-particle azimuthal angular correlations. We demonstrate that characteristic features of hadronic observables such as the baryon to meson ratio, mass ordering of v2(pT) and <pT>, are naturally reproduced within the initial state framework [1]. We also present first results on a systematic comparison of such observables across different systems, including p+p and p+Pb collisions at the LHC as well as p/d/He3+Au at RHIC.
