I purchased the HydraPak 2L specifically for a Spartan Ultra. I wanted to be able to pack a lot of nutrition and gear, and be able to quickly replace the bladder. I couldn’t be more pleased with its performance. Each shoulder pocket carried a Hotshot and gels or energy chews. One front flask carried a water bottle with electrolytes. The other flask held a pair of gloves and my headlamp. On the back the second cargo compartment held some nuts and beef jerky. All of this, and I still had unused cargo space. It was also nice that I didn’t have to stop to grab a gel, dispose of my trash, get my headlamp or gloves. All of the front pockets are easily accessible on the run.
When I made the turn to start the second lap of the Ultra, I pulled my second bladder out out of my cooler. Within seconds I had a full bladder with ice cold water. Just what I needed.
I honestly couldn’t be more pleased with the comfort and performance of this product.
