Jansport Diablo 3L

The Jansport Diablo 3-liter hydration pack gives you unparalleled stability and reliable hydration, while offering space to store essentials. Put keys, snacks, and maybe a camera in the organizer pocket, which comes with a headphone port so you can be your own traveling concert. Stay energized all day with up to 3 liters of liquid, stored in the V-shaped Nalgene-designed Water Tower reservoir—by keeping the water as high as possible, the flow stays consistent throughout the drinking cycle. Jansport's unique Nirvana bite-valve has easy shut-off. It even stores in its own compressible pocket so it doesn't slap against your chest as you descend the peak you just bagged. Jansport's Quick Connect reservoir feature allows you to chill the reservoir without freezing the tube—they come apart and re-connect easily!

A great little Pack.
I really like this pack, and like the Nalgen hydration system much better than camelbak. It's comforable and easy to use. Only drawback is that its size is maxed out when doing a 12 hour activity.

love it
I love my new hydration pack, it's not too big and not too small. It has a great size water resevoir. And I can never get lost with that bright orange on my back.

love the no taste
Hydration system, day pack, and good looks all rolled into one. Aside from the trim fit, comfort wrap, and sleek styling, the Diablo utilizes Jansport’s new bladder technology. They got into cahoots with Nalgene and developed the ‘water tower system’. This is the most ergonomic, practical, tasteless system I have encountered yet. Nicely done Jansport.

Training Tips

After each interval, take your pulse rate by counting the number of beats at your wrist or neck for 15 seconds. Multiply that result by four to get your beats per minute. Your next interval should start before your heart rate is less than 60% of your maximum.

The four components of good fitness include flexibility, muscular endurance, muscular strength, and cardiorespiratory endurance. For optimum health, include at least two of these groups in three workouts per week.

Your fitness level will improve by overloading, working your body hard enough to stimulate the body, progression, increasing the frequency, intensity, and duration of exercise over time, and regularity, working out frequently, at least three times a week.

As your fitness improves over time by following a carefully planned fitness program, your ability to exercise closer to your maximum heart rate will improve.
