Pioneer Camp Men's Thermal Boxer Briefs

Navy is the quieter choice for a damp morning when you plan to stay moving and do not want to think about layers except to add them. These boxer briefs sit close under trousers and base layers, with synthetic insulation that keeps a thin pocket of warmth while the quick-dry finish clears moisture fast. Cloth that stretches follows your movement. Nothing pulls at the jog of a hill.

The trade-off is simple and honest. They are not a heavy insulator for long rests in wind and rain, and they ask that you pair them with an outer layer if you plan to stop for a long spell. In return they save space in the pack and drain faster than heavier pieces after a wet run.

One of 15 on the accessories rail in the Pioneer Camp catalogue. A size letter describes the garment rather than a body, and the way we keep the figures current is set out on how we update the catalogue.
