The Osprey Manta is by far the most comfortable pack I have had the privilege of using for biking. In particular the Manta’s suspension system is superior to the primitive offerings held out by many bike-specific manufacturers. It is well-thought out for cross-country/all-mountain applications, barring some nitpicks. However, it might not be the best pack for anyone who has to carry a lot of armour as it lacks external attachment straps. Continue reading →

Strengths: The best part of Osprey's hydration packs is the Nalgene reservoir. It has a rigid back which helps it keep its shape as you drink, and it slides into a full pack easily. Also the magnetic valve/sternum strap is great.
Nice fit, lots of organizeable storage, rain cover....yadda yadda.
Weaknesses: The Manta isn't specifically designed for biking (like the Viper & Raptor) and is billed as a multi-sport pack. Thus, the Manta isn't quite as pedal-friendly when it comes to pack stability, and lacks "bike-specific pocketing" (whatever that is).
More expensive than some comparable packs but I think you get what you pay for.
This is a great do-it-all hydration pack. If you need a daypack for things besides biking go for the Manta, but if all you do is ride then I'd opt for the Raptor. Osprey makes quality stuff and this is well worth the price.
