Review on Optimized CamelBak Repack LR 4 Hydration Pack with 50 oz Capacity by Mark Bearden

Great solution for transferring fluid from the back (hot and sweaty) to the hips for better weight distribution. The standard configuration wasn't the best as it kinks the line and prevents good water flow due to the way the outlet is set up. I swapped the cord and magnet from the right side to the left side and the difference was huge. At maximum capacity, it holds about 2.5-3 full standard bottles of water. Adequate amount of water for most of my 1.5-2 hour rides (16-20 miles and about 2km elevation), leaving some water (1 bottle?) at the end. The magnetic holder takes a little getting used to (when moving house), but is quite secure. The rear compartment has room for my emergency tools and a mini pump. Some space in the main water compartment also takes up space in the outer water compartment when full. The side pockets are large enough to hold 2 cliffs each. One side has a zip closure while the other is a stretchable sleeve (for easier access to a small iPhone?). All in all a good solution and doesn't move much unless you're really into technical stuff or decent jumps (but still stays stable). The adjustment straps feature velcro attachment straps for oversize and seem to adjust easily for taller individuals. I have a 30ft waist and have plenty of extra belts left.
