I have finally gotten sick of my water bottles sweating all over everything and decided to make a sleeve for them. I literally whipped this one up in like 15 mins, I just wanted to see if something basic was going to work for me. I reused a pair of jeans for this one. It is super simple and after testing it I was pleased that the bottle did not sweat & the jean material was a good fit I thought. But I want improvements. I think a little pocket would be handy for my skinnier bottles to hold my chapstick & maybe cash/debit card. I could probably do a larger pocket for my bigger Nalgene bottle that would hold my phone too. I would also like to insulate them so the stay cooler a little longer. A lot of sleeves I've seen have handles or straps on them but for my personal use I don't see a need in that since I just grab the Nalgene bottle's handle to carry it
I'll post pics of my new sleeves when I get them made with a review.
