Designed by ultra-adventurer Peter Bakwin, the PB Adventure Vest 2.0 will help you go further, higher and harder. Version 2.0 includes all the same great features as the original plus many improvements. Side adjustment straps, hidden in side pockets, allow for a fine tuned fit and elimanates bounce. An added side access zipper and gear storage separator makes accessing and securing a reservoir easy. 340gm Power Mesh is strong and durable, and Silnylon 66 provides increased seam strength. The PB Vest 2.0 is stronger and more durable, enabling you to go anywhere with confidence.
Featuring 12 L of volume and a variety of features, The UD Peter Bakwin Adventure Vest allows you to stay hydrated and comfortable on any size adventure from quick outings to all-day expeditions.
The pack Peter Bakwin always wanted did not exist – so he designed this one. The 12 ounce PB Adventure Vest has the same abundant storage options as the SJ Ultra Vest, but with a large 8.5 litre main compartment, constructed with a unique one-piece pull cord for instant expandability or compression. With a special pocket for a locater beacon, and a system for readily attaching trekking poles or an ice axe, this is the most comfortable pack ever for hiking, running and climbing.
"The Adventure Vest is the pack I’ve always wanted but wasn’t available… until now!”

MATERIALS & DESIGN
Silnylon 66: Impregnating nylon with Silicon and Polyurethane creates this permanently waterproof fabric, and also substantially increases its seam and tear strength.
Hex Mesh: The Hex Mesh vest structure is completely breathable, extremely strong, and lightweight. Its inability to absorb moisture results in a drier, more comfortable wear.
Power Mesh: All pockets are strong and stretchy, made with heavy duty 340gm Power Mesh stretch fabric so the vest expands as you need it to.
