By Graded Backpacks | BJJ Gear and Buying Guides
Two practitioners can train at the same academy and need very different bags. One arrives with a rashguard, shorts and a bottle. The other carries a gi, a second training kit, a towel and everything needed for the commute home.
Your build matters too. A bag can have plenty of room inside and still feel too long or bulky on your back.
Choose a BJJ backpack by checking two things: how it fits your body and how it holds your regular training kit. A compact bag can suit petite and smaller practitioners or lighter loads. A 32L backpack is a useful starting point for a full gi kit and everyday extras.
Here is how to work out which size makes sense for you.
Compact or large: the quick comparison
Graded offers a Small backpack with a compact fit and a Large 32L backpack. Start with their dimensions, then consider what you actually carry.
| What to compare | Small — Compact Fit | Large — 32L |
|---|---|---|
| Dimensions | 15.7 × 11.8 × 5.5 inches | 20 × 14 × 7 inches |
| Approximate metric dimensions | 40 × 30 × 14 cm | 51 × 36 × 18 cm |
| A useful starting point for | Petite and smaller practitioners; a preference for less bulk | Practitioners who want more room for training and daily essentials |
| Training routine to consider | Lighter sessions, no-gi kit or a minimal packing list | Gi training, combined gi and no-gi sessions, commuting and fuller loads |
| The deciding check | Does your complete kit fit without forcing the closure? | Does the larger bag sit comfortably when packed? |
Dimensions are height × width × depth, based on the linked product specifications and measurement graphic. The Small is listed by dimensions; an internal capacity in liters is not specified here.
Your body size and your packing needs do not always point to the same choice. A petite practitioner carrying a full day's gear may prefer the Large. A taller practitioner taking a light no-gi kit may prefer a compact bag.
Start with your usual training load
Before measuring anything, put the things you take to an ordinary class in one place. Include the items you tend to forget when shopping for a bag: the towel, slides, laundry sack and clothes you change into afterward.
A useful packing list is:
- Gi jacket and pants, plus your belt, when needed
- Rashguard, grappling shorts or spats
- Mouthguard and case, tape and personal essentials
- Water bottle and the towel you normally use
- Change of clothes and footwear, if you carry them
- Laptop, charger or work items, if training is part of a longer day
Use your own gi for the comparison. A lightweight gi folded neatly can take up a different amount of room from a heavier uniform with a thick collar. Gi size, fabric and folding all affect the space you need.
Then think about how often the bigger load happens. An extra kit once every few months does not necessarily need to determine your everyday bag. Two sessions after work every week probably should.
When a compact BJJ backpack makes sense
A compact backpack is worth considering if you are a petite or smaller practitioner and prefer a bag that takes up less space on your back. It can also suit adults who pack lightly or want a smaller bag for a straightforward trip to class.
Think of a no-gi session close to home: training clothes, a small towel, mouthguard, water and a few personal items. That is a different packing problem from bringing a gi, work clothes and a laptop across town.
If you train in the gi, check the folded jacket and pants together with everything else you plan to bring. A smaller frame does not guarantee that your full training load will fit a compact bag. You should be able to close the bag normally and reach your essentials without unpacking it completely.
Choose the compact option when its dimensions feel comfortable and your regular kit fits with enough room to pack easily.
When the Large 32L is the better starting point
The Large is a practical starting point if your normal day includes a complete gi, no-gi clothing, a towel and a change of clothes. It also deserves a look when you go directly from work to the academy or regularly stay for more than one class.
Its wide opening, secondary compartment, padded internal laptop sleeve and exterior bottle pockets help organize a mixed load. Check the actual fit of your computer and accessories rather than assuming that every laptop will fit a sleeve.
More capacity also gives you flexibility when the packing list changes. A cooler evening might add a layer of clothing; a longer session might mean a second rashguard or another towel.
That flexibility is useful only if the packed bag feels manageable to carry. Put the items you normally take inside, adjust the straps and walk around before deciding. Leave out extras that you rarely use.

How to check the fit on your body
Height alone does not tell you how a backpack will sit. Torso proportions, shoulder shape, strap adjustment and the packed load all influence the fit.
Start with a backpack you already find comfortable. Measure its height, width and depth while it is resting naturally, then compare those measurements with the Graded sizes above. This gives the numbers a familiar reference point.
When you try a training bag on, check it with a realistic load:
- Adjust both shoulder straps. Bring the bag close enough that it feels stable while leaving your arms free to move.
- Check the strap position. Notice whether the straps sit comfortably on your shoulders or rub against your neck.
- Walk, turn and sit down. Look for swinging, awkward bulk or the bottom of the bag getting in your way.
- Reach the things you use often. Your bottle, keys and mouthguard should be practical to access.
- Check how easily it closes. A zipper under constant tension is a sign to reconsider the load or the bag size.
For petite and smaller practitioners, comparing the bag's height with a familiar backpack is especially useful. For anyone carrying a fuller load, the packed trial matters just as much as the measurements.
Leave room for the trip home
A bag that closes easily when you fold everything carefully at home should also be practical to repack after class.
Allow space for a laundry sack or suitable separate bag for used clothing. Keep it away from clean clothes and work items, then empty the backpack when you get home. A bag's lining does not replace separation between damp gear and a laptop.
You should also be able to put your training kit away without following a complicated packing sequence every time. If a towel or spare rashguard only fits when you force the zipper, a larger option may make your routine easier.
Choosing between sizes
If both options seem possible, use the part of your routine that happens most often to make the decision.
Lean toward compact when you prefer a smaller profile, carry a lighter kit and have checked that your essentials fit comfortably. This can be a good match for petite and smaller practitioners who find larger bags unnecessarily bulky.
Lean toward 32L when a full gi kit, extra clothing or work items are part of your normal load. A smaller practitioner can still choose more capacity if the packed fit feels comfortable.
If you are selecting interchangeable rank straps, check the choices and compatibility for the specific backpack size. Choose your bag dimensions first, then confirm that the strap option you want is available for that model.
Compare the Small — Compact Fit and Large — 32L with your regular training kit in mind. Pick the size you can pack easily and carry comfortably through an ordinary training day.
Frequently asked questions
What size BJJ backpack is a good starting point for an adult?
A 32L backpack is a useful starting point for a full gi kit and daily extras. Adults who carry a lighter load or prefer a smaller profile can also consider a compact bag. Check the packing space and the fit on your body together.
Which BJJ backpack should petite and smaller practitioners choose?
Start by comparing the compact bag's dimensions with a backpack you already find comfortable. Then check your full training kit. A compact fit may suit your build, while a larger bag may better suit what you need to carry.
Is a compact backpack enough for gi training?
That depends on your folded gi and the rest of your kit. Check the jacket and pants together, then add your belt, towel and essentials. Choose more space if the load makes the bag difficult to close or repack.
Does a larger backpack have to be filled completely?
No. You can leave space available for extra clothing or a second session. Pack the items you use regularly, keep the load organized and check that the bag remains comfortable to carry.
