Camelbak Octane XCT 70 Oz Hydration Pack Product Review

I bought the Octane XCT based on the idea that it would perfect for carrying enough water to supply me during my 3-4 hour, 20 mile training runs. It has proven to be a godsend for those that are interested in having as little weight as possible balanced with a pack that doesn't keep sweat next to your skin.

I had a Camelbak for a number of years, but as a 50 year-old (plus) runner, the one I own rode on my hip more than the back [a Camelbak for biking, running, geocaching and/or hiking). The XCT puts the weight on the center of the back so that your center of gravity for running is placed perfectly for forward motion.

I have used this for a 2.5 hour, a 3.5 hour and a 4 hour run. Filled to the top of the 70 ounce capacity - i had enough water to get me the whole way with little left. For a 2 hour run, half full can get you there. My 4 hour run was starting in 68 degree weather and ended in 86 degree weather, so I think it was a great test to see if the XCT held enough to get anyone through such a test.

If you are thinking of using this in a similar manner let me suggest a way to keep your water supply (and yourself) cooler in these runs. First fill the 70 ounce Camelbak with ice cubes 3/4ths to full. Fill up the rest of the bag with water. I didn't have ice at the end of my run but it kept the water cool enough so that after drinking the water in the tube the end of the drink was refreshing. I believe it also helped keep my core temperature cooler.

Overall, I am giving this a 5 star rating. My only complaints is that the storage area is small (I use 9 gels when I run - it was enough space for that) and that the storage areas are not see-through (so that you can tell whats in each area. But it is a trade off for a runner. The more you carry, the heavier it gets, so realistically, it is probably a perfect amount. I am able to carry 9 gel packs, iPhone, iPhone charger, Advil pack, toiler paper in plastic pouch, Power Bar, package of peanuts, $20 cash. iPod Nano, ear-buds and small bag of Jelly Beans. (If you're wondering what else would you need space for - there's enough room for extra gloves, knit hat - cold weather stuff.

Again, an excellent accessory for any runner (or biker for that matter) for those 2 hour plus runs.
