Make a superlight, super speedy alpine ascent, or spend a day at the crag; either way, the Arc'teryx Cierzo 18 Backpack is behind you. The Cierzo's top lid has an adjustable strap that stows climbing ropes outside the pack, leaving plenty of room for shoes, harness, draws, belay device, helmet, and a trad rack. The Cierzo also features a sleeve, hanging clip, and HydroPort for your own hydration reservoir. There are multiple stash pockets for keys, wallet, phone, headlamp, and snacks. The SwiftCord compression straps double as ice axes, ski poles, and other mountaineering tools.

great pack

    This is my third pack around this size, I also own the petzl bug, and the exped summit lite. This one has been a nice addition. I have been using it over my other packs during the winter as the swift cord compression system is great for stuffing layers into as you warm up. It holds a shovel and probe along with other essential gear for ski touring. It kinda sucks loaded down with climbing gear, but so does the bug, it's just the cost you pay for wearing a pack that climbs well.

    Lightweight summit pack w/ some costs

    • Familiarity: I've used it several times

    This is a very lightweight pack with a particular size for very specific uses. I find this pack to be useful for a few situations: (1) a summit pack for big mountain objectives or for multi-pitch rock climbs, (2) a day hiking pack, (3) day-to-day pack carrying small things on maybe your commute to work.

    Here’s what’s good about this pack:
    (1) It is very lightweight. I find that it beats most of the competition.
    (2) It is the perfect size for it’s purpose—enough to carry an extra layer, your water, some food, extra gear (e.g., headlamp, map, keys, phone, etc.)
    (3) Durable and relatively waterproof

    Here’s what I don’t like:
    (1) I don’t like the compression “SwiftCord.” I don’t personally see much of a use for it, and I find it gets caught on things too easily (e.g., trees, rocks, doorknobs).
    (2) The lack of a frame makes things shift around and objects stick into your back if you do not pack it thoughtfully
    (3) I haven’t figured out how to use the key clip. The one of the Alpha FL is much more intuitive.
    (4) I personally find the divider in the external pocket more of a nuisance than benefit

    A little flimsy to carry much

    • Familiarity: I returned this product before using it

    The description for this pack indicates it may function as a Summit pack capable of carrying a rope and other gear for a day climb. I found the pack to be too flimsy for that. Climbing gear is heavy. For a pack suited to climbing I think there needs to be a bit more structure/support so that load carries reasonably well and doesn't move around on your back. This pack seemed more suited to carrying less than 10lbs which fits more in the day pack for hiking not climbing.

    Sorry to hear this didn't suite your needs. If you're looking for a pack that's a little more substantial checkout the Brize packs, available in 25L and 32L sizes. They carry extremely well and are very versatile.

    Perfect summit pack

      This is all that's needed for ground to summit pushes. Perfect size for hauling your approach shoes, water, food and layers. My wife commented that she didn't ever feel like it was there once we started climbing. Great construction and lightweight 👍

      Great design that covers technical needs

      • Familiarity: I gave it as a gift but have feedback to share

      Bought this for my best friend for her birthday, and she loves it. She's used it on overnight backpacking trips with minimal gear (i.e. husbands hauls the tent and other larger items). She said it's super comfortable to hike in and is a perfect size for her needs. However, if you're looking for something for true backpacking, this pack would be a bit too small for that. It holds essentials, but fills quickly. Main uses are mostly day hiking, climbing, and even travel. Makes for a great go-to pack, and can't beat the quality of Arc'teryx.

      She's convinced me to even purchase my own!

      Unanswered Question

      I've noticed that this backpack is "HydroPort" compatible, but does it actually have a sleeve in the main compartment for a hydration bladder?

      Arc'Teryx - Quality you can trust

      • Familiarity: I've used it several times

      The Cierzo 18 is no exception to Arc'Teryx quality. You simply get what you pay for. This is a minimalist, lightweight ascent pack. What you lack in brutal durability you gain in how light the pack is. his is intended to be used as a lightweight day pack, for climbing, etc. Do not expect much padding, that is not what it is intended for.

      There is an internal pouch inside the main cavern, and one pocket on the outside, directly behind the logo. Inside you will find a cinch that tightens the net outside the pack. Pack is almost completely waterproof and very comfortable--as comfortable as an ascent pack can be. There is a smartfixed drawstring and an adjustable clip to tighten the opening to the main pouch. There is an adjustable waist strap and an adjustable sternum strap. The way the sternum strap is connected to the shoulder straps seems flimsy at first, but is in fact surprisingly resilient and strong. It shouldn't rip. Dark Basalt is a very low profile color--I would recommend it.

      Bottom line: Get it--it is a great ascent pack or lightweight day pack.

      Important! Do not select the frame size based upon the pack volume.
      Packs are sized in Regular (R) and Tall (T). Sizing refers to your back length.
      Back Length:
      To determine your size, measure down the spinal column from the 7th cervical vertebra to the level of the hip iliac crest.
      Hip Circumference:
      Hip belt sizing is based on a measurement around the hip iliac crest. Measure around the body at the top edge of the hip iliac crest, approximately 2” below the point at which you would measure your waist.
      Chest Circumference:
      Shoulder strap sizing refers to bust/chest circumference. Measure around the bust/chest at the fullest point.
