This is the pinnacle of design, functionality, and comfort. Now entering its fourth iteration, this pack has had unprecedented amounts of care and attention placed into every square inch. The larger front pockets which feature a drawstring are perfect for holding any of our bottles. In addition, the Alpha 4.0 can also hold a 2L reservoir in its bladder compartment. The Alpha 4.0 features an insulated layer piece that can help keep your gear dry while it’s in the pack, cool you off, keep your fluids cool or warm, or you can remove the insulated layer all together.

Fits well, no to very little bounce even on hard down hill runs on technical terrain.
I’ve put over 100 miles on my Alpha 4.0 using both a 2L bladder and two Ultraspire 500ml soft flasks. I usually carry my iPhone 7 Plus, as well as a key fob and a gel or two. I’ve used the rear shock cords to secure a long-sleeved shirt that I removed when I got hot.
