Buy a sling if you turn up with a paddle, a water bottle and your keys. Buy a backpack if you carry two or more paddles, a change of shoes, and gear for anyone other than yourself. The honest answer for most recreational players is a sling, and most people buy the backpack.
The actual difference
A sling bag is a single-strap bag worn across the body. It has one large compartment, a couple of small pockets, and it is designed so you can swing it around to the front and open it without taking it off. A pickleball sling typically carries one or two paddles, a few balls, and the things that live in your pockets.
A backpack has two straps and distributes weight across both shoulders, which is why it can carry meaningfully more before it becomes uncomfortable. Pickleball backpacks add paddle-specific features: dedicated slots that hold paddles flat, a separate ventilated shoe compartment, and often an insulated pocket for a bottle. The larger ones cross into duffle territory.
The trade is straightforward. A sling is quicker, lighter and less to carry. A backpack holds more and carries weight better. Where people go wrong is buying capacity they never use, then hauling a mostly empty bag to a two-hour session.
How much do you actually carry?
Be honest about this before you shop, because it decides the answer. Count what you brought last time you played. One paddle, a tube of balls and a bottle is a sling. Two paddles because you are mid-upgrade and have not decided, plus court shoes you change into, plus a towel and a jacket for the shoulder season, is a backpack.
Two specific situations push hard toward a backpack. The first is changing into court shoes at the court — shoes are bulky, they are dirty, and a dedicated ventilated compartment is genuinely worth having rather than putting them next to your towel. The second is carrying for someone else: a partner, a kid, or the group's balls and net. Once you are the person who brings things, a sling stops working.
And one pushes toward a sling: walking or cycling to a drop-in session. A sling is far less to think about, comes off in one motion, and does not need a locker.
Comfort over distance
A sling puts all the load on one shoulder. Under about ten pounds and over a short walk, nobody notices. Load it heavier or carry it further and the asymmetry becomes the whole story — this is the complaint people have about slings, and it is entirely a function of weight rather than design. If your walk from the car is thirty seconds, it is irrelevant. If you commute with it, it is not.
A backpack is the better long-carry option by a wide margin, but only if you use the capacity. An oversized bag carried half-empty is worse than a right-sized sling, because the bag's own weight and bulk are working against you for nothing.
Side by side
| Consideration | Sling bag | Backpack |
|---|
| Paddles carried | Typically 1–2 | 2–4+ in dedicated slots |
| Shoe compartment | Rare | Common, often ventilated |
| Access while wearing | Swing to front, open — fastest | Take off both straps |
| Comfort loaded | One shoulder; fine when light | Both shoulders; better under load |
| Best for | Drop-in sessions, walking, minimal kit | Full kit, shoe changes, carrying for others |
Our picks either way
On the backpack side, the Selkirk Sport Day Backpack is the right-sized choice for a normal session and our overall pick here, while the JOOLA bag is the one to buy if you genuinely carry a full kit and want thermal pockets and four-plus paddle capacity. On the sling side, the Franklin sling is the budget answer and the Athletico crossbody is the more organised one.
