Atom Packs Pulse Backpack Review
Reading Time: 11 minutes The Atom Packs Pulse is from UK-based Atom Packs and is part of a trio from the company that I’ve been able to test extensively over the past couple of years (the other two being the Prospector and the Atom).
Atom Packs backpacks, including the Pulse, usually come in a few standard sizes, but the real draw is the vast customization the company offers. You can tailor your pack to match your needs and preferences perfectly (but be warned, designing your dream pack can be surprisingly addictive).
The Pulse falls between the Prospector and the Atom in size and carrying capacity. It’s the perfect choice for anyone looking for an ultralight pack that still boasts an internal frame and full-size hipbelt. Lightweight enough to keep your overall pack weight low, it can still carry enough gear, food, and water to handle the slightly heavier loads sometimes demanded by multi-day backcountry stints.
Here’s everything you need to know about the Atom Packs Pulse.

Testing Conditions
I took the Atom Packs Pulse along whenever I didn’t need the extra capacity offered by the Atom Packs Prospector. This has included multiple week-long fall trips through California’s Sierra Nevada and Emigrant Wilderness, where I saw sun, snow, rain, and more. I typically use it with the hipbelt, but lately, I’ve been leaving the hipbelt at home and using the pack with just the sternum strap as support.
Notes on the Pulse
Consider the following when considering the Atom Packs Pulse and my impressions of it. My pack has the following configuration:
- 40L Pulse
- Two Avocado Pockets (I would not necessarily recommend any, and I’m not even sure that two is an option anymore)
- Bullet Net mesh for the front pocket (after using an Atom Packs Atom with the Dyneema Stretch, I prefer the Dyneema Stretch)
- Two Fixed Shoulder Pockets (recommended)
- Bottom Pocket (recommended)
- Y-Strap Top Strap (recommended for carrying more/larger items – like a bear canister)
- Elastic side compression (I like it for the color)
And yes, if you’ve read my Atom Packs Prospector review, the following will sound very familiar (because both packs are stellar for many of the same reasons).

The Good
The Customization
The Pulse shines when it comes to customization. Atom Packs takes a tailored approach with top-notch quality and service in a space where personalized options are increasingly rare. Customers can customize virtually every aspect of their pack, from the torso and hipbelt size to the color of almost every panel. Beyond that, you can choose pocket materials, shoulder strap and bottom pocket options, top strap configuration, front elastic, side compression straps, and even the color of the tabs that secure the front elastic. The sheer number of choices makes designing the Pulse almost as enjoyable as using it.
The Shoulder Strap Pockets
The optional shoulder strap pockets on the Atom Packs Pulse offer easy access to essentials and are something I wouldn’t consider getting my pack without. Located within easy reach on either or both sides, they’re perfect for stashing frequently used items like phones, snacks, or even bear spray (remember to keep your bear spray within reach and not buried in your pack). I typically carry a 700 ml water bottle with a sport cap in one, allowing for hands-free hydration (when the bottle is full). The stretchy material ensures a snug fit, preventing items from bouncing. For any camera-wielding users, it’s important to note that a larger camera mounted on a Peak Design Capture might obstruct access to that shoulder strap pocket unless the camera is positioned particularly high or low.
The Comfort
The Atom Packs Pulse offers a highly customizable fit with four torso lengths and seven hip belt options. It’s designed for comfortable carrying up to 30 lbs / 13.5 kg – perfect for extended backcountry trips with just the right amount of gear. The Pulse is an excellent choice for venturing into the world of ultralight backpacking who aren’t ready to commit to an entirely frameless pack like the Atom Packs Atom (or who want the option to more comfortably carry slightly heavier loads when called for). The removable padded back panel features shaped, 8mm closed-cell foam that can be removed to shave 0.53 oz / 15 g off the pack’s weight. I’ve packed my Pulse to the gills and have always been pleased with its performance. The pack includes a carbon fiber frame that can be removed for an additional 1.94 oz / 55 g weight savings.
The Hipbelt
The Atom Packs Pulse has a removable hipbelt that’s available in seven sizes – from XS (28-30″) to XXXL (40-42″). Removing (and reequipping) the hipbelt is a simple process as it’s held into the discrete sleeve at the base of the pack with velcro. On short trips or when you’re not planning to carry much, it’s easy to ditch the hipbelt and save some weight. This hipbelt also offers a comfortable, customizable fit thanks to its ample padding and multiple adjustment points. No pockets are included, but not to worry for the pocket lovers out there. Optional hipbelt pockets are available for those wanting a little extra storage, or for anyone who hasn’t embraced the fanny pack revolution (yet).
The Company
I met Tom Gale, the founder of Atom Packs, on the Continental Divide Trail in 2017 (at the Toaster House), and he’s come a long way since then (both figuratively and literally). A thru-hiker himself, he understands the needs of serious backpackers and started his company in order to fill a hole in the backpacking world. Based in the UK’s Lake District, the Atom Packs crew takes pride in their work. Unlike a lot of the outdoor industry, when you get in touch with Atom Packs, you’ll connect with a fellow outdoor enthusiast who values your input beyond simply being a consumer. I encourage you to check out their story if you haven’t already.
The Okay
The Avocado Pocket
The Avocado Pocket is a mesh pocket that can be added to the side of your pack (visible in the photo gallery above) that I really want to love. Alas, I can’t bring myself to appreciate the true value I know it has the potential to live up to. It’s an optional mesh pocket – for an additional fee – that lives on the side of your pack and would be perfect for – in theory – storing an avocado. One reason I’m not a fan? It makes your pack asymmetrical. I need symmetry in my packs. Another reason I’m not a fan? Mine’s too shallow. That said, it looks like Atom Packs has now updated the Avocado Pocket to make it deeper, hopefully adding some versatility to it.
The Bottom Pocket
A standout feature of the Atom Packs Pulse is its bottom pocket, perfect for stashing items you need readily accessible. If you’re designing a custom Pulse, I highly encourage you to add one to your pack. It easily accommodates smaller items, but I have struggled slightly to get my larger jackets in (but once they’re in, there’s no risk of them falling out). While the pocket can be a bit snug, requiring extra effort for larger items when the pack is full, the convenience and organization outweigh any struggle. Being able to access it without taking off the pack is awesome. There’s also a tiny corner of the bottom pocket that’s open – the corner closest to your back on the left – perfect for stuffing trash into while you’re hiking (just don’t forget to empty it at the end of the day).
The Hipbelt Pockets
The Atom Packs Pulse has optional hipbelt pockets. If you’re a fan of hipbelt pockets (i.e., if you haven’t yet embraced wearing a fanny pack while backpacking), these might be an additional cost you aren’t ready for when purchasing a pack and may seem like having to buy stakes with a shelter. However, the ability to easily add and remove the pockets makes the Pulse more versatile. The pockets are padded and weigh 1.24 oz / 35 g each. If only they were available in fun colors like the custom packs are.
The Price
While the Atom Packs Pulse isn’t the cheapest pack on the market, its price point reflects its exceptional value, landing in a sweet spot between budget-friendly and ultra-premium (i.e., overpriced). The high-quality materials, meticulous craftsmanship, and thoughtful design in each pack justify the cost. What truly sets the Pulse apart and makes it a fantastic deal is the extensive level of customization available. This bespoke approach means optimal fit and functionality, maximizing comfort and performance. Investing in a Pulse means investing in a pack built to last while ideally suited to your needs.
The Waterproofness
While the Atom Packs Pulse is water-resistant, it’s not fully waterproof. In wet weather, a pack liner (or cover – though liners are generally more effective, lighter, and less bulky) is a must. Frankly, even with supposedly waterproof packs (unless they’re designed like dry bags), I always use a liner anyway. Is this a deal-breaker for the Pulse? Not at all. Would it be great if it were completely waterproof? Of course.
The Bad
The Name
The Atom Packs Pulse has a name change history, which might cause some confusion. Formerly known as the Atom Packs Atom+, it was renamed in 2024. While the change itself isn’t a problem, it does mean that people familiar with the “Atom+” might miss the “Pulse,” and new customers might be puzzled by online references to the old name. Just to be clear, it’s the same pack. Atom Packs has tried to communicate this change clearly, but some online mentions of the “Atom+” might still trip up newcomers.
The Lead Times
The wait is the biggest downside to the Atom Packs Pulse (and Atom Pack’s other packs). Whether you’re going custom or trying to snag a pre-made pack, lead times can be significant, sometimes stretching for months. This can be a major issue if you’ve only just decided that you will start your massive cross-country adventure hike next week and want an awesome pack ASAP. While the quality and customization are worth it, the long wait is something to consider. Pro tip: Order now; your future self will thank you.
The Previewing
One of the downsides of the Atom Packs Pulse is that it’s difficult to try on before you buy. Since they’re online-based (unless you live near their Lake District workshop – they might be in a local shop or two?), you can’t easily check the fit and feel beforehand. This is frustrated by the fact custom orders are non-returnable. So, if your pack isn’t a perfect fit, you’re still committed to it. Plus, you’re responsible for all shipping costs (which, yes, are to/from the UK). This lack of a try-before-you-buy option may make some buyers hesitant (hopefully, this review helps!). If you’re unsure about sizing, contact Atom Packs – they’re happy to offer guidance.

Who It’s For
Beginner Backpackers
If you’re new to backpacking and unsure if it’s a long-term passion, investing in a high-end pack like the Atom Packs Pulse – with its potentially long lead time – might not be the most practical first step. However, if you’re seeking a durable, versatile, and unique pack built to last through years of hiking, even up to a Pacific Crest Trail thru-hike, the Pulse is worth considering.
Weekend Warriors
If “backcountry” is part of your regular vocabulary and you get genuinely excited about your gear, the Atom Packs Pulse deserves your attention. It’s my go-to recommendation for outdoorsy friends looking for a lightweight pack for shorter trips or who want to call themselves “ultralight” (but who aren’t ready to commit to a frameless pack fully – but if you are, there’s the Atom). If you’re not picky about customizations, you can usually find one during their regular drops.
Thru-Hikers
Aspiring thru-hikers should consider the Atom Packs Pulse, which was made with long-distance backpacking in mind. If your gear is of the ultralight variety, but you’re still trying to be sure you’re ready for anything out on the trail (i.e., you’re not one of those people who doesn’t carry a shelter or rain gear), the Pulse is more than capable of comfortably carrying all your gear. That said, the Prospector may be a better option if you plan to do 10-day food carries and have a chair as part of your current gear list.
Wrap Up
The Atom Packs Pulse hits the sweet spot in the middle of the ultralight-functional Venn diagram.
For those seeking a durable, feature-rich, and customizable pack that can live up to the expectations of a day hike, a weekend out, or a thru-hike, the Pulse should be a serious contender. That said, if you think you’re going to need something that can carry a slightly heavier load, it’s worth taking a look at the Atom Packs Prospector as well.
While the potentially lengthy lead times and the inability to try the pack on locally before purchasing may be an obstacle for some, if you find yourself able to overcome these hurdles and put your faith in the words of an internet stranger (that’s me), do yourself a favor and place your order now (and make sure you add a bottom pocket and shoulder strap pockets if you’re customizing).
