LBP P&G___ P&G frame extension Bayonet systems can be put on any LBP Packs 36, 37, 38, 39........Little Big Packs for an additional $89.00. See the LBPpage for regular LBP prices. This adds the Bypass Harness at the same time. Pack shown is an LBP 37 in various stages of extension. The pack is made of Navy HT420 and Gray Full Dyneema. Photos 6 & 7 show the bayonets removed and in the forground of the photo. Photo #9 shows internal detail of the pack. The broad black band of fabric is where the top of the lower main frame ends. At the base of the lower main frame (photo # 10), at the bottom of the pack, is the Q-Bayo adjustment arm that comes with all LBP packs, even those that do not have the P & G option added. The pack bag actually shortens when the Q-Bayo swivel is shortened, providing a micro adjustment for the pack that on the average is about 1" in length. The main function the Q-Bayo serves is to allow the pack to transform through two different harness configurations. The Q-Bayo allows the pack to have 4 different frame lengths and harness combinations to allow optimum fit with different load weights. Scroll to end of page for White Dyneema LBP 37 P&G.
