Vest Pack optimized for Urban-Training™ activities to store pocket items in a comfortable and secure design that fits like a hybrid between a slim backpack and a vest. Straps can be secured tightly for high-intensity activity or left loose for commuting. The Vest Pack features two main front pockets (both fit iPhone 8 Plus) and one large back pocket (fits iPad or hydration pack). The outer fabric of the Vest Pack is Hipora® Waterproof technology and it is lined with 3M™ Thinsulate™ for low-profile insulation and padding.
Hipora is a three-layer microporous membrane that blocks water from coming in but allows moisture to get out. The first layer has pores with a diameter smaller than 0.5 μm, small enough that water cannot enter but large enough that moisture can escape. The second layer is a honeycomb structure that absorbs any moisture leaving your body and holds onto it until it has left through the first layer so that you never feel the sweat on your skin. The third layer is an extremely dense layer to reinforce the shielding against water.
3M™ Thinsulate™ is an extremely thin yet powerful insulation technology. It contains extra fine microfibers that trap body heat to keep the wearer warm while also allowing for a slim profiled garment with maximum range of motion and minimum bulk. Thinsulate™ also allows moisture to escape through its fibers, making it the perfect synthetic insulator for high performance sportswear.
