Full disclosure: Petzl sent me this pack for free. That in no way biases my review; I think it's great and I want to tell you about it. There are no ads, affiliate marketing links, or paid product promotions on Alpinesavvy. In the rare cases when I get free products like this, I’ll always let you know.
The button below links to my favorite climbing goodie store, HowNOT2. I provide it as a convenience; I make $0.00 if you buy from them.
My first time on El Capitan was a test run of the Nose up to Sickle Ledge. Among various other minor mishaps that day, the Yosemite granite managed to grind a silver dollar sized hole in the side of my favorite alpine climbing pack, because I didn't have a proper haul bag.
The Petzl Bug would've been a much better choice!
While Petzl makes packs for caving, canyoneering, and industrial / rope access, this is their only offering for climbing; specifically, multipitch rock climbing.
That gets my attention. I've had a few different versions of small climbing packs over the years, notably, the Black Diamond Bullet. Up until now, the Bullet was fine. I now like the Bug a lot better.
The Bug has gone through several iterations over the years. This latest version, at 18 liters and 665 gram / 1.5 pounds, has a few understated features specifically for multi pitch rock climbing. It’s also versatile enough to kick around town as a commuter / student pack, if that's your thing. It comes in several colors; I like the classic black and orange.
My first impression out of the box: “Dang, this is a solid, well designed workhorse!”, and not “This is so featherweight, I wonder if it can handle being a mini haul bag?”
Here’s what I like about the Bug.

Sturdy and smooth zippers
Two well-placed zippered interior pockets

(Disclaimer: The photos below will make it wildly obvious that I’m not a product photographer, but I gave it my best shot.)
Sturdy and smooth zippers
Probably the most common failure point in all outdoor gear is crap zippers. Not a problem with this pack. The exterior zippers are beefy, and they have sturdy pull tabs so you're never fumbling to open anything.
Two well-placed zippered interior pockets
One of them has a key clip. These pockets are nicely tucked away in the main body of the pack and not attached to the lid, where you can easily drop things if you forget to zip it closed. (Not a problem in a commuter pack, but potentially a Big Problem on a cliff.)
Sliding adjustable sternum strap
Each sternum strap is clipped to a little plastic bit that slides on a rail in the pack strap, giving you about 5 inches / 12 cm of up and down adjustability. Especially for a small pack, this can give a more comfortable fit.
Large front panel pocket
When your pack is all buttoned up, especially with a rope on top so you can't open the main compartment, a pocket like this gives quick access to smaller items. (It opens vertically, so be sure and zip it back up.)
Sits high on your body
This pack doesn’t have waist belt gear loops. You want a pack like this riding fairly high so you can access your harness gear loops.
Padded back panel and shoulder straps
Yes, this adds a touch extra weight, but it also keeps your climbing hardware from poking you in the back and definitely adds comfort on the hike in. A good trade-off, if you ask me.
Water bladder / reservoir sleeve in the back panel
The large water bladder sleeve has a small clip loop at the top. This loop keeps your half empty water bladder from slipping down inside your pack, which can be annoying. There's an exterior hole for your bladder tube.
I'm generally not a fan of water bladders for cold weather alpine climbing. However, for warmer rock climbing, they can be handy. This sleeve fits my 3 liter reservoir.
This well-padded bladder sleeve is also a good spot for a guidebook, so it doesn’t get crunched in the main part of your pack.
If this is your urban pack, an laptop or iPad also fit fits nicely in the bladder sleeve.
Now, let's look at some of the climbing specific features of the Petzl Bug.
Durable exterior
The first thing you notice: the extra stout, rubbery material on the top and front panel. It feels like an industrial tarp, or almost a truck inner tube. I've seen similar reinforcement on canyoneering packs, where gear really gets beat up. This is great for long-term durability when dragging your pack up a cliff. It also might offer a fair bit of waterproofing (which you hopefully wouldn’t often need on a rock climb.) It’s both a distinctive look and very practical.
Sturdy haul loop
Nice to see on a pack designed for multi pitch rock climbing. This haul point is burly enough so I'm comfortable clipping only to this loop and not using the shoulder strap as a backup.
Easy access when clipped to the anchor
Related to the haul loop design: the Bug hangs nicely when you clip the haul loop to an anchor. The 3/4 zip clamshell top opens away from the haul loop, so you can access everything in the main body while the Bug is clipped in.
The clamshell top means you can never unzip the bag down the sides and have important things fall out, pretty key for a climbing pack.
Helmet pouch
You're not gonna fit your helmet into an 18 liter pack, so this is pretty important. I’m not a fan of having my helmet bouncing around on the outside of my pack on the hike in, so this pouch is pretty nice. It's easy to add or remove the pouch as needed.
Daisy chain loops and compression straps on the side
The side compression straps are long enough so you can strap down a rope so it behaves better on the outside of your pack. The top of the compression straps can be unclipped from the body of the pack, which makes it easier to put the strap around your butterflied rope. Combining the side straps with the main rope strap on the top, the Bug carries a rope better than any other small pack I've used.
The sewn daisy loops work for clipping pretty much anything else on the outside of your pack, like your smelly shoes or a messy chalk bag.
If you don't have much stuff, you can crank down the compression straps to make the pack even smaller.
Shoulder strap clip loops
A small loop of cord or webbing on the shoulder strap gives a convenient place to rack gear as you’re cleaning, maybe keep your nut tool handy, or keep the next few pieces of gear you think you'll need on lead in a quick-to-grab spot.
I've added gear loops to my other alpine packs, see this article. I don't have to on the Bug; there's one on each shoulder strap.
It’s also a handy spot to clip a two-way radio, if that's your thing.
Removable waist belt
The waist belt straps are girth hitched, so you can easily take them off for a more streamlined haul.
What's the clever design feature with the rope compression strap?
How well does the rope carry system work?
