MAK Swimwear
Men's Endurance Training Jammer
£34.00
The MAK Endurance Training Jammer is built for the pool, not the beach. A chlorine-resistant polyester-elastane fabric holds its shape and compression through extended training cycles, while the wide internal waistband and external drawcord keep the jammer firmly in place through tumble turns and kick sets. The knee-length cut reduces drag compared to board shorts and is the standard choice for club and squad training.
Flat-lock internal seams prevent inner-thigh chafing on long-distance sessions, and the four-way stretch construction allows a full kick without restriction. Available in UK waist sizes 28–40, the Endurance Jammer is the go-to training bottom for male swimmers at every level.
