A basic drawstring bag can be useful when you need something lighter and simpler than a full backpack, but buying a multipack also raises questions about material quality, size, and how much each bag can realistically carry. The COIDEA Drawstring Backpack 6Pcs set gives you six lightweight polyester bags designed for gym gear, sports, travel, swimming trips, parties, and other everyday uses. Its main strengths are the six-bag format, foldable construction, reinforced corners, and DIY-friendly surfaces. Its biggest limitation is equally important: the current product specifications list it as not water resistant, so it is better for dry everyday carrying than for protecting valuables from rain.
Quick Verdict
Rating: 8/10
Best For: Buyers who want several simple, lightweight drawstring bags for gym clothes, sports gear, travel organization, events, or DIY projects.
Bottom Line: The six-bag COIDEA set offers practical value when you need several basic sack-style backpacks rather than one feature-heavy bag. The polyester build and reinforced PU leather corners are useful, but you should not buy it expecting weather protection or the organization of a traditional backpack.

What Is the COIDEA Drawstring Backpack 6Pcs Set?
The COIDEA CBT6808-DSCSBB-X6 is a six-count set of lightweight drawstring backpacks. Each bag measures about 16.5 by 13.5 inches and uses a simple cord closure that also functions as the shoulder straps.
The main body is polyester, while PU leather reinforcement is used around the corners where the drawstrings place stress on the bag. That construction is more practical than an unreinforced fabric sack when you plan to open, close, and carry the bags regularly.
The set is designed as a simple carrying solution rather than a technical backpack. You get one main compartment rather than padded laptop storage, structured organizers, or the multiple sections found on larger gym and travel backpacks.
Who Should Buy It?
Best For
- You need several basic bags for a family, team, event, class, or group.
- You want a lightweight sack for gym clothes, towels, shoes, or sports essentials.
- You want plain bags that can be personalized with a logo or pattern.
Skip If
- You need reliable rain or splash protection for the contents.
- You want padded straps, laptop protection, or extensive internal organization.
- You regularly carry heavy or bulky loads that are better suited to a structured backpack.
Detailed Features and Build Quality
Polyester Body and Reinforced Corners
The main bag material is polyester, including the listed outer material and lining. The product is also described as a soft-shell design with lightweight, non-stretch fabric.
The useful detail is at the lower corners. COIDEA reinforces these cord attachment areas with PU leather. Drawstring bags concentrate much of their carrying force around these points, so reinforcement is a sensible feature for repeated everyday use.
This still remains a lightweight drawstring sack. You should not expect the structure, padding, rigid base, or load distribution of a conventional backpack.
16.5 × 13.5-Inch Size
Each bag measures approximately 16.5 × 13.5 inches. That gives you a useful flat area for items such as exercise clothing, a towel, smaller sports accessories, or other flexible essentials.
The listing also describes the bag as suitable for carrying exercise clothes, shoes, and towels. How comfortably those items fit will depend on their size and how tightly you pack them.
Amazon currently lists a storage volume of 1 liter in its specifications. Because a soft drawstring bag changes shape depending on what you put inside, check the current product details and physical dimensions if exact capacity is important to you.
Simple Drawstring Closure
The cord system keeps the design uncomplicated. Pulling the cords closes the top opening, and the same cords act as shoulder straps when you carry the bag.
This makes the bag fast to open and close, but it also means there is no zippered main opening. Small loose objects are better placed in a separate pouch if you do not want them moving around inside the main compartment.
Foldable Design for Storage
The soft polyester construction lets you fold the bags when they are empty. That is useful if you want to keep one in luggage, a vehicle, a locker, or a larger travel bag until you need an extra carrying option.
A foldable bag also takes up much less storage space than a structured daypack. The tradeoff is that it offers little shape or impact protection for fragile contents.
Six-Bag Multicolor Set
The package contains six bags in a multicolor set. A multipack makes more sense than a single bag when several people need their own sack or when you want separate bags for different activities.
You can also use different bags for gym gear, travel accessories, sports equipment, event supplies, or household organization instead of repeatedly emptying one bag.
DIY and Personalization Potential
COIDEA specifically promotes the bags as suitable for adding logos or patterns. That can be useful for parties, clubs, teams, group activities, simple promotional packaging, or craft projects.
If you plan to print, press, paint, or otherwise customize the polyester surface, confirm that your chosen decoration method is compatible with polyester and follow the instructions for the materials or equipment you use.
How It Performs in Real Use
For Gym and Sports Gear
The 16.5 × 13.5-inch format is well suited to a basic change of clothing, towel, or lightweight sports accessories. The drawstring opening is also faster to access than a bag with several buckles or compartments.
For heavier equipment or a full gym load, a structured gym backpack with padded straps will usually be more comfortable.
For Travel Organization
Because the bags fold flat, you can pack one or more inside your luggage and use them later for day activities, laundry separation, shoes, or lightweight purchases. The six-count package gives you several organizers without requiring six structured backpacks.
Do not use the bag itself as moisture protection. Keep passports, electronics, and other sensitive items in appropriate protective cases when conditions are wet.
For Beach or Swimming Trips
The bag can carry a towel, swimwear, or other lightweight beach items, but the listing’s lack of water resistance is important here. Wet clothing can also transfer moisture to other contents.
Use a separate waterproof pouch for phones and valuables, and isolate wet items when needed.
For Parties, Groups, and DIY Projects
A six-pack can be especially practical when you need matching bags for multiple people. The simple polyester surface also gives you room for names, patterns, or other customization when you use a suitable method.
This is one of the areas where the COIDEA set has a clear advantage over buying one more expensive individual sackpack.
Tips for Better Everyday Use
- Avoid overloading: A drawstring sack is better for flexible, lightweight belongings than dense or heavy equipment.
- Protect sharp objects: Keep pointed or abrasive items inside another pouch so they do not press directly against the polyester shell.
- Separate wet gear: Use another waterproof or leak-resistant bag for wet swimwear and towels when necessary.
- Balance the contents: Distribute items evenly so one side does not pull harder on the cords and reinforced corners.
- Follow the care instructions: The product is listed as machine washable, but check the label on your specific bags before washing.
Pro Tip: If you use different bags for gym clothes, shoes, travel items, or family members, label or customize them before regular use. The six-bag set is easier to manage when every bag has a clear purpose.
Materials, Care, and Weather Protection
The verified main material is polyester, with a polyester outer layer and lining. The bag uses a soft-shell, non-stretch construction and PU leather reinforcement around the corners.
Amazon lists the care instruction as machine wash. Follow the attached care label for your specific set, particularly after adding printed logos, paint, transfers, or other DIY decoration that may require different washing conditions.
The most important limitation is water protection. The current specification is Not Water Resistant. You should not assume the polyester fabric will keep the contents dry in rain, around a pool, or during a wet beach trip.
Pros and Cons
Pros
- Six bags in one package for families, groups, events, or separate uses.
- 16.5 × 13.5-inch size works for many lightweight gym and travel essentials.
- Polyester body with PU leather reinforcement at the drawstring corners.
- Foldable design is easy to store inside luggage, lockers, or larger bags.
- Plain multicolor design supports DIY logos, names, and patterns.
Cons
- Current specifications say the bags are not water resistant.
- Simple drawstring construction lacks the padding and organization of a full backpack.
- Cord shoulder straps may be less comfortable when you carry heavier loads for long periods.
Is It Worth the Price?
The COIDEA set makes the most sense as a budget-oriented multipack. Instead of paying for padding, frames, laptop sleeves, or complex organization, you are getting six simple polyester bags intended for basic carrying and repeat use.
You get the most value if you genuinely need several bags. Families, teams, party organizers, teachers, travelers, and DIY users can divide the set among different people or purposes. If you only need one everyday backpack and plan to carry electronics or heavier items, investing in one more structured bag may give you better long-term utility.
How It Compares to Alternatives
If you want a single established drawstring sack instead of a six-pack, the HOLYLUCK Drawstring Backpack and adidas Alliance Sackpack are worth comparing. They make more sense when your priority is one dedicated sports bag rather than multiple inexpensive bags.
If extra organization and weather protection matter more, a model such as the WANDF Drawstring Backpack, which is sold with additional pocket features and water-resistant positioning, is also worth comparing. The COIDEA set remains more appealing when quantity, simple construction, foldability, and DIY use are your main priorities.

The reinforced corners and simple 16.5 × 13.5-inch design support everyday use, but buyers who need water resistance, padded carrying comfort, or advanced organization should choose a more structured backpack.
