When buying a smell proof bag, you have the option of choosing between disposable or reusable bags. That being said, we recommend reusable for the purpose of sustainability and space efficiency.
Disposable bags cost significantly less, but are extremely small, prone to breakage, and of cheaper quality than reusable bags. They need to be tossed after one or two uses, which isn't environmentally friendly.
Reusable bags are bigger and made of more expensive materials or fabrics. Rather than hold in odors, they can filter out odors just as effectively. Their shelf life is also significantly longer, which helps justify the more expensive price tag.
Material
While disposable smell-proof bags are mostly made of plastic, reusable options are made from more complex materials and fabrics. Reusable bags often feature a durable nylon exterior, which protects your marijuana from liquids and potential rips. Other materials like bamboo and cotton may not last as long and may experience more wear and tear, but have a more elegant aesthetic and texture.
Size
Smell-proof bags come in a range of sizes, depending on your needs. Highly compact models that are just 2 x 3 inches are available, and so are large crossbody and case-style bags which can be more than a foot wide, several inches deep, and six to eight inches tall. These bags are useful if you travel with multiple smoking accessories.
Closure
While this is about preference, choosing the right bag closure system is also about safety. If a bag is not sealed properly, smells can escape, and children can potentially access your marijuana. Zipper closers are functional, but the most effective type of closure is a zipper combined with a hook-and-loop or velcro, with a foldable top edge.
