Osprey Momentum 32 Backpack Black One Size

I owned the last generation bag which lasted about 5 years. I liked the bag but after spending 3 months with the new version, I can definitely say the current bag is a big improvement over the older model. Improvements include: - more rigidity, especially if the bag has a light load - because of the improved rigidity and the better zippers vs. the older model, closing pockets s much easier - how the compartments and the pockets are laid out is well designed...each has a useful function - the shoe pocket is awesome - the ventilated mesh back is a major improvement - the addition of drink pockets are welcome but not well implemented As noted in other reviews, the drink pockets are a bit odd and I miss the front pocket of the old model. It was useful for stashing a rain jacket. But without a doubt, the new model is a major improvement over the old model. FWIW: I use the bag when motorcycling, cycling, traveling (as a carry-on/day tripper) and everyday commuter.
