This is a work in progress. So far I have completed the following mods. The new weight with all the current mods is 3.1oz. down from 3.88oz factory weight:
1. Removed the velcro from shoulder straps, and sewed up the slits. No padding inside.
2. Removed velcro from extension collar and sides, replaced with Aircore 1 Spectra and micro barrel lock. The G6 has a rolled edge at the top of the collar that accepts the drawcord. Ahh. No more velcro bites on my nice wool top. And no more gear falling out on the trail when the top comes unrolled from my poor roll up skills.
3. Removed overly robust, difficult to adjust webbing from shoulder straps and pack body, replaced with 5/8″ grosgrain webbing and kept stock 5/8″ buckles. I really like the feel of this mod. The straps adjust much more smoothly. Most of the weight decrease came from this mod. But, will the grosgrain hold-up?
4. Added Cuben Fiber stake bag inside pack above shoulder strap area. Weight: 0.8g (yup, not even a gram).
Next:
5. Add sternum strap.
