Alpha FL 30L Backpack

The Arc'teryx Alpha FL 30 Backpack embraces a minimalist design, but that's not to say it's a bare bones pack. Climbers need plenty of gear, so the dual haul loops, front bungee system, lash points, and ice axe loops are more of a necessity than luxury. The roll-top closure sports an additional drawcord that lets you expand the pack when you need a little extra room for layers or food. But if you're wanting to pack light, the top rope strap doubles as a compression cinch to keep those smaller loads from slopping around and pulling you off balance.

Even ultralight packs need a little structure, so Arc'teryx designed the Alpha FL with its AC² suspension system and HD 80 rigid foam backpanel for support and comfort. The body of the pack is composed of lightweight ripstop fabrics that can squeeze up chimneys and drag against ice without shredding, and the webbing waist belt and removable sternum strap increase carrying comfort, without adding bulk. All the external WaterTight zippers keep rain and snow out of your gear, and the seam-sealed construction ensures that prolonged exposure to wet weather won't leave your sleeping bag soggy and your packed layers soaked.

Durable and Versatile!

I've used it several times

I have used this pack from some canyoneering and it does great! The fabric is super durable so you don't have to worry rubbing up against canyon walls or wearing a hole in it. The inside of the bag is white, so it makes finding your gear super easy also, it isn't a black hole. Also, with the roll top design and such, the bag is waterproof, so you can toss it and not worry about it sinking! Would recommend if you are looking for a light, simple, and durable bag for canoyeering, or anything else. Works great carrying a rope over the top for days climbing. Can't go wrong with this pack!

Great for canyoneering

I've used it once or twice and have initial impressions

So I got this pack for a canyoneering trip down in Southern Utah. I absolutely loved it. I got the 45L for my husband and I actually think the larger size was a better option, especially if you're going to be carrying one of the ropes. I did carry a 100ft rope, a wet suit, snacks, harness with gear on it, and water. It was a really tight fit, but worked. The minimal hip belt is perfect to have when wearing your harness. It doesn't get in the way but still is nice to have when hiking up the canyon before rappelling down. We were in water where we couldn't touch and the packs were completely water proof. This was really nice because not only did our stuff inside stay dry, they weren't saturated at the end of the rappels so they weren't any heavier. They also floated which was great. They're super lightweight and nice and narrow. We had to squeeze through some tight spots and they didn't hinder us at all.

My favorite daypack..... EVER.

I've put it through the wringer

The Alpha FL30 has become my favorite daypack ever for a variety of reasons. I have been backpacking, hiking, peak-bagging and climbing for over 30 years now, and also worked briefly at my local gear shop. I am a certified gearhead and have owned/used many, many packs over the years. What this pack is NOT: It is not a plush, heavy, pack with multiple pockets and organizational features. It does not have a frame or beefy suspension, and no compression straps. No hydration port or bladder pocket. However...... What this pack is: 1. SUPER lightweight at 1lb5 oz.(20-ish OUNCES!) 2. It carries extremely well for being so minimal. It's amazing, actually. Ask anyone who owns one, they all will say the same thing. 3. It has a stiff, foam framesheet and thin, but very comfortable shoulder straps that carry the load well. I am comfortable with 20-25 lbs in this pack, all day. Additionally, the 40mm webbing waistbelt is actually wide enough that if you cinch it up, it can take some of the load off your shoulders and transfer it to your hips. Load lifter straps are not needed with this pack. 4. For me, this pack is versatile enough to be used for climbing, day hiking, peak-bagging, or traveling, even though it is designed as an alpine climbing pack specifically. However, I tend to favor simple packs. I like to use water bottles instead of a bladder, mostly because I tend to spend a lot of time in the Rockies and Cascades at higher elevations, and I'm a flat-lander who lives at sea level, so I tend to have difficulty drinking on the fly and sucking wind simultaneously! I prefer to take water breaks every hour or so, like what is typical during a mountaineering trip. So I am used to pulling out my water bottle and the lack of hydration port on The Alpha FL30 is not an issue for me. You could however, run a hose out of the top opening, in good weather. Which brings me to my next point..... 5. This pack is HIGHLY water-resistant, almost waterproof. It is constructed of a coated and abrasion resistant fabric, and all seams are taped. It has an internal roll-top closure like a dry bag, and a drawstring closure at the top, like a stuff sack. If you roll down the internal closure and cinch the external drawstring tightly, very little if any, moisture will get in. I only do this if it's raining or snowing. In good weather, I leave the roll top open for ease of access to my gear. 6. It is super simple to attach your ice tools and crampons to the front of the pack. Also, I often use the bungee system for stashing trekking poles, or a puffy. In summary, Arc'teryx designed a great pack specifically for alpine climbing but I find I can use it for many other activities. Its great strengths are its light weight, simplicity, weather resistance, and how well it carries whether climbing or hiking. If fits me like it was custom made for me. For reference, I am 5'9'' tall, 185 lbs, and I have a 19 inch torso. Is it worth $219? Probably. But if you shop around you can often find it for less. I bought both of mine for 30% off. Unless you're a guide who spends hundreds of days in the mountains, you will not wear it out. It should last for years or a lifetime. Sometimes, LESS really is MORE....

Incredible Pack

I've put it through the wringer

Love this thing, It's an absolute dream in the Mountains. The simple design and thoughtful construction make this pack work amazingly well in the Backcountry. Probably my new favourite pack. It being durable enough to throw your crampons on the outside without any thought of damaging it is super nice! And the waterproofness of this pack is stunning. Will definitely be using this bag more.

The best

I've put it through the wringer

I love this pack and everything about it. I have used this pack for both technical purposes (i.e., climbing and hiking) as well as just basic commuter/daily purposes and I find it works great for both. However, it clearly is designed, and excels the most, in the alpine environment. Pros: (1) The pack is amazingly lightweight for its size (there is a caveat to the size I will mention later). (2) It is incredibly durable and water proof. I personally have yet to tear a hole into this pack or managed to have any water permeate it whatsoever. (3) Simplistic design with just enough support in its frame and straps (4) The design allows it to hold tightly to your body, which is incredibly important in a pack while climbing. (5) Easy to manipulate (i.e., open the main and external compartments, put on/take off, adjust straps, unclip waistbelt) in the freezing cold while wearing multiple layers of gloves. Hell, although I haven’t tried, you could probably do everything you need to even with mittens on. (6) Ice axe/tool attachments are easier to use than traditional attachments (7) Crampon straps work great. I thought my crampons would have cut these by now, but I have yet to have any issues. Also, you can use the straps for other things you need to attach on the outside (e.g., helmet, belay jacket) (8) I actually find the key hook in the external pocket quite useful most of the time. That said, I am not carrying my house keys on me for big alpine objectives and haven’t found a use for it then. Cons: (1) Expensive, but it find it is worth it (2) It lacks the external attachment points that are found on the Alpha FL 45. I found these quite useful for the 45L version, particularly for attaching boots for approaches. (3) The size is a bit deceiving, as the size in the name of the product is actually the size with the roll top fully expanded.


This bag... holy cow

The lightest and most durable water resistant bag I've ever used. Check out my in depth review below!

Excellent over view and to the point review. Thank you Ari I.

Good, But Not Perfect: Too Minimal

I've used it several times

This backpack carries well for how simple and light it is. It's somewhat expensive (not as expensive as Cilogear), but that's expected of any Arc'teryx product. Despite every positive aspects of this backpack, I feel like Arc'teryx tried too hard to save every gram and it's too minimal for me. For example, Alpha FL45 has side loop webbing while Alpha FL30 doesn't. Not sure why. It's missing other basic features that are found in other competitors and I wouldn't have minded extra 50g~100g for features that are lacking on this backpack.

ideal climbing pack

I've put it through the wringer

Just returned from two weeks in the Bugaboos climbing every day with this pack and couldn't be more pleased with it. Highly recommended for what it was designed for; climbing alpine rock routes with a pack. It's super light, with very tough waterproof fabric, streamlined without a lot of external loops and straps that just get caught on rock, and carries weight well while climbing. There are probably better and cheaper options for casual and hiking use, but this is perfect as an alpine/multipitch rock climbing pack.

Great Speed Pack

This is a great pack for fast hikes and peak bagging. The construction is solid and the pack carries well. Really like the coated canvas construction and cinch top.

Keep it simple.

I've put it through the wringer

I bought this as a gift for my husband and this is what he had to say: “Using the K.I.S.S. method Arc'teryx nailed it with this pack. It has everything I need, and nothing I don’t. The expandable 30L capacity has plenty of room for food, gears, and extra layers for a day in the mountains. The weatherproof roll-top closure is another nice touch, and while I generally fold it down for easier access, it brings great peace of mind while carrying camera gear if a storm was to roll in. The pack had no problems keeping water and moisture out while getting caught in several storms. Most importantly though, Arc'teryx nailed it in the comfort department with a great shape to the shoulder straps and very comfortable foam. While the simple waist belt is comfortable and can easily be wrapped around the bag when not in use, I would have liked to see a removable waistbelt and maybe some additional padding there for added comfort.”

tougher than it looks

I've put it through the wringer

have used it the last couple weeks strapped to the back of a motorcycle doing adventure trips, as well as Grade 3 and 4 climbs. The material is surprisingly durable. Favorite part is the closure system on the top.. it's a really great balance. you can either be quick for when you are lazily just walking to the beach, or need to roll it up tight to keep out dust and water. Also, there's just the right amount of features... It's a great break from all my other packs that are heavy laden with pockets and straps.


Is the Alpha FL 30L able to be rolled or folded to be stored in a larger pack during the approach to a multi-pitch climb?

Hey Chris! You won't be able to remove the back panel on this pack
