For those of us who keep a water bottle within arm's reach, and those of us who really, really should.

The Hydration IRLA Pack is a 5-coin hydration challenge built around one simple goal: drink more water. Five achievements scale from "I signed the pledge today" to "I drank a gallon a day for a month straight." You can finish the challenge in about five weeks if you're committed, or take your time and ease into it.

The Hydration IRLA Pack covers one of the most basic, most ignored, most quietly life-improving habits we could think of. The challenge ramps up gradually from signing the pledge to drinking a gallon a day for a full month. In between are checkpoints at one week, two weeks, and three weeks. Each one earns you a real, physical IRLA coin.

Some people will breeze through this challenge in five weeks. Some will need three months. A few will buy this pack, set it on a desk, and not crack open the seal on coin number 2 until next year. All of that is fine. The Major IRLA at the end, Aquaholic, doesn't have an expiration date. It'll be there when you're ready.
