Best kids drawstring gym bags for 2026
The adidas Alliance Sackpack is our best kids drawstring gym bag because it adds bottle pockets and a zipped outer pocket without becoming a bulky backpack. A sackpack is best for PE, swimming or after-school kit, not as a replacement for a child's everyday book bag.
What to look for in kids drawstring gym bags
Start with the kit, not the logo. A child carrying football boots or a change of uniform needs a roomy top-loading compartment and cords that can be shortened to sit securely on smaller shoulders. A bag used only for a T-shirt and shorts can stay much lighter. Before buying, ask whether a water bottle needs to travel outside the main compartment, whether keys or a phone need a separate zipped space, and whether wet weather is a regular part of the route to school.
Pockets are more useful than they sound. When a bottle shares the main compartment with a school polo shirt or a dry towel, a loose cap can make the whole bag inconvenient. External bottle pockets keep that item separate and easier for a child to reach. A zip pocket does the opposite job: it stops small items from disappearing under trainers. The Alliance has both kinds of pocket; the Undeniable takes storage further with two specialised front pockets.
Materials and base construction matter when the bag spends time on a muddy touchline, changing-room floor or wet pool deck. Water resistance does not make any drawstring bag a sealed dry bag, but a repellent outer finish and protected base can be worthwhile for damp commutes. The Under Armour Undeniable has UA Storm water-repellent treatment and a TPU-coated bottom panel that extends up the front. The Ozsee is the simpler alternative, with durable material, an easy-cinch drawcord and a sternum clip to keep the cords in place.
Fit deserves attention too. A small child should be able to cinch the bag shut and pull the cords over both shoulders without the load swinging against their lower back. The Ozsee listing gives full dimensions of 18 by 14 by 2 inches and a 16 L volume, which is a useful reference point for a light PE load. Do not overload any of these bags with textbooks or a heavy laptop: narrow cords concentrate weight more than padded backpack straps.

1. adidas Alliance Sackpack: best overall
adidas Alliance Sackpack
The adidas Alliance Sackpack earns the overall badge because its simple main compartment is supported by the practical extras most children actually use. The listing specifies an easy-cinch opening with durable cording straps, two drop-mesh water-bottle pockets and a zippered exterior pocket for a phone or small items. That combination keeps a drink out of the clothing compartment while giving a bus pass, locker key or snack a fixed place. It is a strong fit for a child who moves between school PE, clubs and weekend practice and needs one bag that is easy to pack independently. The tradeoff is the lightweight, unstructured format: there is no padded laptop sleeve or separate shoe compartment, and the cords are not ideal for carrying a very heavy load over a long walk. It is best when the contents are sports essentials rather than a full school day.
Pros
- Two drop-mesh bottle pockets separate a drink from clean PE clothes
- Zipped exterior pocket gives small essentials a defined home
- Easy-cinch opening and durable cording help children pack and close it quickly
Cons
- No padded section for a tablet, laptop or fragile schoolwork
- No dedicated shoe compartment, so dirty trainers share the main space
2. Under Armour Undeniable Sackpack: best for wet-weather kit
Under Armour Undeniable Sackpack
The Under Armour Undeniable Sackpack is the more protective choice for a child whose practice kit sees rain, wet grass or a damp changing-room floor. Its UA Storm finish is described as highly water repellent, while the tough TPU-coated bottom panel continues up the front for extra durability where the bag is most likely to be set down. Storage is unusually considered for this style: the full-length insulated front zip pocket can work as a bottle sleeve or valuables pocket, and there is also a fleece-lined front valuables pocket. Adjustable cording straps can be tied for a custom length, with MOLLE webbing on the front for attachment points. Give it the badge if weather protection and organisation outweigh minimal weight. Its limitation is that those layers and pockets make it more complex than a basic gym sack, and it still lacks the padded back and wide shoulder straps of a conventional backpack.
Pros
- Water-repellent UA Storm finish is useful for a wet school run or pitch-side wait
- TPU-coated bottom panel adds protection where the bag meets the ground
- Insulated full-length front pocket can separate a bottle or valuables from kit
Cons
- More structured front storage adds weight and complexity versus a basic sackpack
- Cording straps and an unpadded back remain less comfortable for heavy books
3. Under Armour Ozsee Sackpack: best lightweight pick
Under Armour Ozsee Sackpack
The Under Armour Ozsee Sackpack is the right choice when the bag's job is simply to carry a light change of clothes, trainers and a drink without adding unnecessary bulk. Amazon lists durable material, an easy-cinch drawcord and a sternum clip that keeps the cords secure and in place. Its stated full dimensions are 18 by 14 by 2 inches with a 16 L volume, giving families a concrete sense of the space before ordering. That makes it well suited to a younger child carrying PE gear, a swim towel or an after-school club kit who benefits from a simple bag they can close themselves. The limitation is storage separation: unlike the Alliance it does not provide the two bottle pockets and exterior zip pocket, and unlike the Undeniable it does not offer the insulated front compartment or TPU-protected base. Pack damp clothing in a separate bag and reserve the main compartment for essentials.
Pros
- 16 L stated capacity suits a compact PE, swim or club kit
- Sternum clip helps keep drawcord straps from slipping apart on active children
- Easy-cinch opening keeps the format simple for independent use
Cons
- No dedicated exterior bottle pockets or zipped small-item pocket
- Simple main compartment is less useful when wet kit and clean clothes must stay apart
FAQ
Are drawstring gym bags suitable for school PE?
Yes, provided the bag is used for a light PE kit rather than a full timetable of books. Look for a main compartment that fits the required clothes and trainers, then choose pockets according to the routine. The Alliance is helpful when a child carries a bottle and small items; the Ozsee is better when the kit is minimal. For a heavy school load, use a backpack with padded straps instead.
How should a child carry a drawstring bag comfortably?
Place the heaviest item low and close to the back, tighten the drawcords so the bag does not hang too low, and use both straps rather than one shoulder. Check that the cords do not dig in before a longer walk. The Ozsee's sternum clip can help keep its cords in position, while adjustable cords on the Undeniable can be tied to a more appropriate length.
Can a drawstring bag carry wet swim or sports clothes?
It can, but use a separate sealed pouch for wet clothing so it does not soak dry kit, school papers or snacks. The Undeniable's water-repellent finish and coated base help with outside moisture, not with containing a wet swimsuit inside the bag. Air the bag and the kit as soon as possible after use to limit odour.
