Arc'teryx Cierzo 35 Backpack -
Arc'teryx designed the Cierzo 35 Backpack to be a lean summit-bagging machine. The ultra-lightweight, super-strong materials give you a maximum strength-to-weight ratio so you can pack the necessities without adding even an extra gram. And, this highly compressible pack stuffs into its top lid so you can pop it out for a speedy single-push ascent or a full-tilt alpine climb.

Support and Cushioning:

  • The 2cm webbing waist-belt adds support without getting in the way of your harness
  • EV50 foam cushions your body, resists compression damage for longevity, and will not freeze (at least not in any temperatures found on this planet)


  • Removable frame sheet and sternum strap make the Cierzo versatile so you can use it for just about anything

Weather and Wind:

  • Invista HT Mini Ripstop and Invista HT Ripstorm fabrics are over-coated with silicone for strength and water-shedding and under-coated with PU for waterproofing and seam stability


  • Four compression straps stabilize your load


  • Dual ice axe loops and removable ice axe keepers give you a place to keep your tools

Arc'teryx Cierzo 35 Backpack Reviews:


It's always hard to find a light summit/day pack in this size without a frame. Good for a follower or a leader/long day in the hills. Fabric is more durable than similar packs with the flimsy siltarp material.
Pros: light, holds a lot, durable for the weight, no frame (removable bivy pad), compresses enough to stuff in a larger pack, rope strap on top, Micro daisy for clippin' rockshoes, helmets, etc. Removable ice tool holders.
No hydration port (easily fixed with a knife). But really!? Such a drastic oversight makes me wonder what other oversights I'll discover later on.
Shoulder straps designed for barrel chested tumblers. I'm 5'8" and need to pull the shoulder straps completely tight. So basically, they made the fabric/padded portion of the shoulder strap insanely long.
Next model? Add a floating lid, hydration port, stretchy side pockets (cilogear has this dialed), and a longer/thinner strorm collar so you can get more torso into the bad during a shiver bivy. Also a re-enforced loop on the other side of the rope strap so you can double back the strap over the rope, making it more secure.

I bought this pack for a superlightweight climbing/scrambling bag. It fits that bill, but the main hip belt buckle broke after a week, and the bag buckles feel like they could go at any time. I haven't sent it back yet, so I really can't complain, but this bag definitely has a less than sturdy feel to it, almost cheap. I guess that's to be expected with a pack this light, but a bit offputting for a company like Arcteryx, where everything I've bought in the past has been bomber.
