We have no idea. First off, you ask...then buy...you are doing things assbackwards. Second, you can't ask the internet this type of question and get an answer worth a damn as some people are light on stuff and some people stomp on everything they own and treat it like shit.

Sally....may use her 18 bag as a glorified lunch bag and it lives in her passenger seat or next to her chair in a climate controlled office. She sews cute patches on it, launders it once a month in woolite and air drys. She will arrive shortly and post a lovely haiku singing the praises.

Carl...internet naysayer, uses his 18 bag in his job as the guy who cruises every neighborhood in his 84 Chevy with catty-wampus bed looking for scrap metal to stuff it with. And its stored amongst beer cans and rust water in the bed. He cleans it by beating it on the fender and watching the rust cloud add to his mesothelioma index. He will arrive shortly and tell you its a piece of shit and then say something bad about your mother.

Read the above. Then read it again and see the wisdom. Treat your stuff nice. Ask, then purchase. A $1 IKEA bag will outlast the universe, so when yours do die, put them in an IKEA bag.
