What Our Gearhead(R) Experts Are Saying:"I took the Blaze 60L Backpack on a five-day loop in the Wind Rivers with a loaded pack pushing 40 pounds, and the Air Current frame made it feel manageable from start to finish. The Re-Fit hip belt was a revelation on uneven terrain because I could micro-adjust the fit mid-trail without stopping to dig through the pack. The hidden front zipper also became one of my most-used features by day two, getting to my rain gear fast without having to unpack the entire top."Five days in the backcountry has a way of exposing every flaw in your gear, and nothing makes itself known faster than a pack that doesn't fit right. Granite Gear designed the Blaze 60L Backpack around the idea that fit is not a one-size-solves-most problem. The Air Current frame adjusts precisely to your torso length, and the patent-pending Re-Fit hip belt dials in from 24 to 40 inches so the load rides on your hips instead of grinding into your shoulders by mile eight. At 60 liters, there's room to do a trip right without resorting to creative packing gymnastics. The main body fabric is 100D Robic high-tenacity nylon with a Barrier DWR treatment, while the corners and high-wear zones step up to Granite Gear's exclusive 210D Robic UHMWPE triple ripstop, one of the most abrasion-resistant materials available in a pack at this weight. The removable lid converts to a chest pack for summit days, the hidden front zipper puts your buried gear within reach in seconds, and the S-shaped shoulder harness keeps the whole system sitting comfortably against a women's specific frame from the first mile to the last.
