If you're looking to bag a few summits this year, you'll need to take along your trusty companion, the Nathan HPL #020 2L Race Vest. This vest is lightweight and fits comfortable across your shoulders. You'll be able to carry 2 liters of water and barely notice it's there. There are pockets on the shoulder straps so you can store energy bars and electrolytes that way you can push through the fatigue and reach new heights. A sternum strap comes across the front of this pack to keep it secured and a hydration tube clip will secure the tube to your chest so it's not bouncing around and you can find it quickly. For the ultimate adventure where you'll need a plentitude of water, take this light weight pack along with you.
