There are people in this world who drill holes in $2 toothbrushes because they are too heavy to take on the trail. Crazy, right? How much of a difference does that really make — three, maybe four grams? That’s a handful of paper clips! To average day hikers, such a thing is unfathomable. But thru-hikers understand. These are the brave men and women who spend weeks on the trail, sometimes months. This particularly insane subdivision of hiking requires the absolute lightest, most reliable gear. Every ounce counts. The following kit highlights essential pieces of thru-hiking equipment, all of which are among the lightest available today.
Hyperlite Mountain Gear 2400 Windrider

The Hyperlite 2400 Windrider is perhaps the lightest thru-hiking backpack in its class. Every single detail of the pack is built to achieve two purposes: exceptional strength and lightness. Most of its thru-hiking prowess is owed to the Dyneema shell — a miraculous fabric that might as well have floated down on golden clouds as a heavenly gift from the gods of thru-hiking. Those mythological figures, it turns out, are right here on Earth, and they are assembling Hyperlite packs in Biddeford, Maine.
