This backpack is so amazingly light , while also being very rugged and durable. I was worried that the EPX was some type of compromise but it does not seem to be so. This pack is stylish, the lightest I’ve seen, and made of incredibly durable fabric. Definitely worth the cost.

When you're logging back-to-back 20+ mile days and stretching the distance between resupplies, you need gear that won't blink when you push past your limits. The Arc Haul UltraEPX is purpose-built with the space, strength, and adaptability long-distance hikers demand.

Engineered with Ultra 100X and EPX 200 fabrics, this pack blends high-performance durability with a fresh splash of color. The signature Curved Carbon Fiber frame creates a ventilated gap between your back and the pack; keeping you cool and comfortable through long climbs and hot miles.

Three different styles of adjustable shoulder straps and an interchangeable padded hip belt offer excellent weight transfer, keeping your load stable as you navigate switchbacks or rocky descents. Modular add-ons let you tailor your gear setup; because every hike is different, and your pack should adapt to your journey.

  • Made primarily from 3.3 oz/sqyd Ultra 100X fabric with an added panel of Ecopak EPX 200 for a splash of color.

  • Ultra fabric features a woven Ultra High Molecular Weight Polyethylene (UHMWPE) face fabric laminated to a waterproof backing. Ultra fabric boasts extremely high abrasion and tear resistance and is the strongest fabric we offer.

  • Ultra fabric is waterproof, PFAS Free, and is not coated with DWR or other chemicals.

  • Ecopak EPX 200 features 100% recycled components, is waterproof, has a C0 DWR, and has a 70 denier Ripstop backing to provide better stitch holding and superior strength.

  • While the is pack is reasonably water resistant, it does not featured taped seams. As such, we recommend adding dry bags or a pack liner for additional protection for important items like your clothing and sleeping bag.

  • Our Arc Frame curves naturally away from your back, leaving a cooling air gap. It prevents that sweaty pack feel and keeps your gear from digging in. Plus, it transfers weight to your hips helping your hike feel effortless.

  • With 60L of volume, it’s ideal for 5-6 day adventures with ultralight gear. Lash on extras with the included top strap and base straps on longer carries. Roll down the top and cinch down the sides to compress the volume on short trips.

  • Side compression cords let you cinch things down or carry extra essentials like trekking poles or an umbrella standing in the side pockets.

  • Choose your ideal strap style—each one padded with comfy 3/8" closed-cell foam and breathable 3D mesh underneath to soften the load. An adjustable sternum strap and daisy chains let you tailor the fit and clip on must-haves.

  • Our interchangeable padded hip belt features V-style webbing that hugs the contours of your body—more secure, and more comfortable than traditional belts. It’s built to move with you, not against you.

  • Each side pocket holds up to two 1L bottles and is angled for easy reach. No need to take off your pack to stay hydrated. The pockets have drainage holes and snug elastic at the top.

  • Store wet gear, or quick access items in the large stretchy mesh center pocket. Let wet gear dry while you move forward.

  • A drinking tube can be threaded out the corner of the roll top closure and just secured using the daisy chain on your strap.

  • All standard Bear Canisters will fit in the upper half of this pack standing on end. Use your sit pad and clothing as padding around the canister to fill out the space.

  • The short and medium frames fit in most airplane overhead bins.

  • The shoulder straps can be adjusted up or down for a perfect fit using our patented torso adjustment mechanism. It works like a conveyor belt. This is great for sharing the pack between people, or for growing teenagers.

  • Our torso height adjustment mechanism is is covered by US Patent No. 9,848,687. Our Flexed Arc Frame is covered by US Patent No. 9,060,590.
