If you’re like me and keep trying to go on runs during a heat wave, you know how important it is to properly hydrate. And as our runs get longer, and the temperatures creep higher, a standard water bottle just doesn’t cut it. Good news for serious runners looking to upgrade their hydration game: Prime Day has great deals on running gear this year. Right now, this Nathan hydration pack/running vest is 46% off, down to $97.60 from a retail price of $180.

Nathan Men’s Pinnacle Race Vest 4L Hydration Pack

With its 4-liter capacity, this Nathan Vest provides ample storage for both hydration and essential gear, featuring two water-resistant pockets, two kangaroo pockets, and a sleek shape designed for breathability during intense training sessions. I’m especially drawn to the moisture-wicking tapered back panels, which should prevent the friction that typically causes discomfort during extended wear. Still, it never hurts to apply a little anti-chafe Body Glide before your run.

Storage capacity often determines the practicality of a hydration vest, and this vest delivers 244 cubic inches of intelligently organized space. The new side pocket provides easy access to your phone, keys, or energy gels.

Most importantly, he vest comes with two 20-ounce hydration soft flasks. With a vest system like this, you can get consistent hydration access without the sloshing or shifting that can disrupt your oh-so-precious running rhythm. The soft flasks compress as you drink, reducing bulk and maintaining the vest’s streamlined profile throughout your run.

This vest particularly benefits trail runners, ultramarathoners, and anyone regularly running distances that require mid-run nutrition and hydration. Still, road runners tackling any sort of “long run” will appreciate just how much a game-changer running vests are when it comes to proper hydration. For a more minimalist (and more affordable) alternative, I recommend the 50oz CamelBak Hydrobak Hydration Pack, currently 30% off at $42.26.
