Today I’m discussing one of the best lightweight backpacks on the market. The Hyperlite Mountain Gear 2400 Porter. This cuben fiber backpack weighs only 1.91 lbs and is one of the most popular packs for lightweight backpacking and thru hiking. One of the most popular backpacks on the Appalachian Trail and the Pacific Crest Trail, this pack perfectly blends comfort with functionality. A great addition to your lightweight backpacking gear needs!
