Light Weight, Good Fit
Nathan makes some of the best endurance packs out there. They are light and tuff. When I picked up my first pack (Nathan 020 and carries 70 fl oz of liquid) I was worried about the construction of the pack as it appears that it won't take the beating of all day riding/racing. I used the pack all fall on long rides and raced with it this winter without flaw. The pack still feels and looks new. Excellent front stash pockets making gels and electrolyte accessibility easy. The pack is kind of like a fishing vest that is fit for your body with the adjustment straps to cinch down the play in the pack. The pack sits nice and snug without any play or sway. The Synergy pack is a bit big for most of my endeavors but built for the trail. If you are looking for a smaller tighter pack look at the Nathan 020 and 008. The 020 is a smidge bigger than the 008. These are perfect for 6 hour rides/tours/crust cruising and races. Ride On.
