Query: Cheap and very functional but not sturdy

This is a great jacket to stuff in your bag to have on hand. Extremely lightweight and VERY waterproof, but also breatheable, so you don't get horribly hot when you wear it while biking. At the same time, it keeps you warm on a chilly morning. The only (and rather serious) trade off for this deal is that the jacket rips pretty easily. The material is not terribly sturdy so if you wear this jacket a lot, you are likely to shred it within a season as I did. At the price, it isn't hard to replace each season, but I wish I didn't have to replace it all the time.
