I was pretty pleased when this daysack arrived in the post, but I soon discovered that what is generally a useful (but rather small) item is seriously let down by cheap zips. I immediately found myself struggling to open or close them, especially when the sack was full-ish, and within a few days a couple of 'kinks' had developed on the main zip. I also found that the zips snagged on the fabric, and sometimes found it difficult to find the ends (I think both these last mentioned problems caused by weather strips that are tailored too tightly). I write in the past tense as yesterday, after no more than 6 weeks of use, the main zip gave out and I have had to discard the sack!
Won't be buying from Karrimor again unless the quality of the zips is clearly better than those on this Chinese-made model.
