ION’s Vector Vest Amp Front Zip features a unique material mix and highly flexible materials packed in sophisticated design, adding to its safety properties. Strategically placed padding ensures enough space for your harness to maintain freedom of movement, which is even more improved by a super flexible outside lining. The outside lining is our premium lining and is accompanied by Dry_Grid Material on the sides. This reduces drying time and is less water absorbent. Thanks to its flexibility it fits your body perfectly.
