Some hiking trips are straightforward: you go out, you camp in one or two locations, you come back. Others are much more meandering. You might make a base camp and then take side trips. Do you really want to haul your bulky, framed pack on a 3-4 hour side hike? You want to have the right gear for the adventure at hand, and it can be really nice to have a smaller option for cargo at your disposal. A detachable daypack built right into your main pack can fit that bill perfectly.
Detachable backpacks are also practically indispensable for long treks. If you’re backpacking across Europe or braving the Appalachian Trail, having a detachable daypack can mean a world of difference for what you have the option to do. Want to take a break and go into town? A daypack is a super convenient way to carry your daily essentials!
But not all detachable daypacks are created equal! Our guide will help you choose the backpack system that’s right for you, and we’ll even show you how to add a detachable daypack to the backpack that you already have!

What To Look For
When choosing a backpack with a detachable daypack, there are several things to keep in mind. First, you have to think about what you’ll be using the backpack for and make your decisions from there. We have a great post on how to choose a backpack based on volume and sizing here, and much of this information is just as true when choosing a backpack with a detachable daypack.
Weight
An integrated daypack may add weight to your backpack. In some cases, this is negligible. This is especially true for convertible daypacks, which might unzip to form a top cover. But if you have a zip-off pack, it might be more than you want to deal with, and you may have to adjust what you usually carry.
Carrying Capacity
Generally speaking, daypacks can only hold essentials for the day and are 30 liters or smaller. You would never take just a daypack on a multi-day trip because of how little they hold. Most daypacks have a carrying capacity of 10-30 liters.
To make things easier, we’ve created this simple chart to help you think about what situations call for what size of a backpack.
| Duration of Hike | Recommended Backpack Capacity |
| Half-Day Hike (<4 hours) | 20 liters or less |
| Full-Day Hike (>4 hours) | 20-40 liters |
| 1-3 Night Hike | 40-50 liters |
| 3-5 Night Hike | 50-70 liters |
| 5+ Night Hike | 80-110+ liters |
Size of Daypack
No matter what you plan on using any backpack for, you must size it correctly to avoid irritation or even injury. This is true for your detachable backpack! Even though it’s part of a larger system, you need to make sure that both packs fit well. Every human body has slightly different proportions and carries weight differently, so make sure that your daypack fits just as comfortably as your main pack before you take it out on the trail. Your daypack should fit snugly on your body– not too tight and not too loose.
Materials
Most hiking packs and daypacks are made of nylon. The best of these packs are made with ripstop nylon, which is woven specially to be resistant to ripping and tearing. You can also find good hiking packs with detachable daypacks made from polyester or other synthetic fibers. These can be a bit heavier than nylon packs, but they often come with increased water resistance.
Cost
Good hiking gear is an investment that can last for years, and it’s also an investment into your safety and wellbeing. Don’t be lured by cheap, untested packs made with flimsy materials. If your pack breaks on you or puts uneven pressure on your back, you can have a miserable experience– maybe even a dangerous one!
But don’t also think that you simply must have the most expensive gear. What you want to look for is solid construction, good materials, and expert craftsmanship. It’s possible to get great backpacks while sticking to a budget.

Osprey Aether Plus 70/Ariel Plus 70
Osprey makes several amazing hiking packs with detachable daypacks, but we chose the Aether Plus 70 for men and its sister pack, the Ariel Plus 70 for women as our recommendation for a number of reasons. First, the daypack isn’t a separate backpack that’s zipped on. It’s actually just the top lid of the pack– it’s a convertible! More reasons to love the Aether and Ariel series include the easily adjustable torso and hip belts, the roomy compartments, and the light weight.
Both the Ariel and Aether bags share the same great features. The only differences are the contour and length of the back panel and the contours of the shoulder straps.
Size And Weight
- Main Pack Capacity: 70 L
- Daypack Capacity: 16 L
- Total Pack Weight
- Aether: 5.6 lb for S/M bags; 6.2 lb for L/XL bags

Osprey Farpoint 55
Osprey’s concern for physical support is evident even in their lighter bags. Case in point: the Farpoint, designed as a travel bag, has a pared down internal frame that means that this bag– which can be used as a carry-on for most airlines- can hold about 50 pounds of luggage. Lockable sliders protect the main compartment, and both the main pack and daypack feature a reinforced, scratch-proof compartment for your smaller tech devices and glasses.

Thule Landmark 60L
Thule Landmark Travel Pack
The Thule Landmark series of travel packs comes in three sizes: the 40, the 60, and the 70. We’re recommending the 60 because unlike the 70, the 60 is designed as carry-on luggage. If you don’t mind checking a bag, you might want to size up to the 70– but if you want to spend as little time in the airport as possible, the 60 might be ideal. The Thule Landmark is perfect for travel, with excellent interior organization and a sizable daypack that’s big enough to hold even a large laptop!
Size And Weight
- Main Pack Capacity: 40 L
- Daypack Capacity: 20 L

DIY Detachable Daypack Solutions
If you already have a hiking or travel backpack that you just love, but you want to add additional flexibility, there are ways that you can add a daypack to your existing bag. It might not look as integrated as a backpack system with a built-in detachable bag, but looks aren’t everything! Don’t ditch your beloved, trusty, comfortable backpack just because you want a detachable daypack. There are things you can do to add this convenience to gear you already have.
Clip Or Strap On Your Daypack
Depending on how you pack your main bag, you might not have room to stash a smaller daypack inside. Fortunately, most hiking bags are made with options to clip, lash, or otherwise attach additional gear. A couple of carabiners on the outer straps of your bag can be a secure, easy way to attach a daypack. You can clip it to the outside back of the pack, or you can clip it to the top of your shoulder straps and bring it down like an extra top lid. This has the advantage of adding an additional layer of protection in any inclement weather, on top of giving you access to a daypack. You might want to consider an ultralight bag like the barely-there Osprey Ultralight Stuff Pack for this– an ultralight bag won’t weigh you down and most are light enough that you won’t even feel additional strain.
At Hiking And Fishing, we attach our Dagger 22 to our backpacking pack just strapped on the outside. This 22 size gives us the ability to do long and strenuous day hikes after backpacking into a basin.
Sew It Yourself
If you’re really handy, you can actually make your own detachable daypack! Although gear designers like Kelty founder Dick Kelty, Gregory founder Wayne Gregory, and Osprey founder Mike Pfotenhauer all hand-sewed their first homemade backpack designs, you don’t need to reinvent the wheel… or the backpack! There are lots of patterns and awesome DIY communities online. There’s even sites dedicated to teaching you how to make your own bags and hiking gear. It’s important to pick a good pattern and get good materials. You can get your fabric online, at fabric stores… or even IKEA, if you’re really creative (and you love the blue and yellow color scheme)!
Go Foldable And Add A Pouch
Many hiking backpack designers know that hiking can be unpredictable and that each hike might require different gear than the one before it. Take a look at the straps and webbing. You might find that even if your backpack doesn’t have the space to add a whole daypack, it might have space for the addition of a smaller pouch… in which you can place a foldable daypack! Some foldable daypacks like the Lucien Hanna 20L Lightweight Backpack come with their own zipper pouches. Others, like the Ozaeo Lightweight Foldable Daypack, come with cinch-style pouches that can hang from any spare loop or strap.
We know there’s a lot to consider when choosing a backpack, and what you’re looking for and what you need for your adventures is unique to you. But detachable daypacks are such an incredibly useful piece of equipment that we feel that many hikers can benefit from them. If you haven’t tried taking a daypack with you, why not give it a shot? You might find that they open up a whole new world of side trips and travel. Happy trails!
