The Rab Proton jacket is a versatile lightweight insulated layer, built for active use in the mountains. Designed to balance warmth and breathability, it’s ideal for hiking, climbing, scrambling, and everyday outdoor wear where you need reliable insulation without overheating.

A great all-round piece that works well as an outer layer in milder conditions or as a mid-layer under a shell when the weather turns.

Every item we sell at ReTrail is individually checked, cleaned where needed, and assessed before being listed. We only stock gear we’d genuinely use ourselves — focusing on performance, reliability, and real outdoor value.
