Hotslings also does Solarveil in the summer. What specific qualities are you looking for? Any Solarveil pouch is going to be water-friendly, quick-drying, light and cool, and provide sun protection. Features to think about would be: double or single layer (double gives more sun protection), adjustable or non-adjustable, etc.
Well, I know I would like something I could wear in the pool with my dd who is 7 1/2 months old. I also have a 3 year old who loves to run off sometimes. I haven't tried a pouch before and really want too. I don't like ring slings. I liked the guard that the Mammas Milk pouches had. At least they sounded good and they are cheaper. I like that they are adjustable too because I think I might try to wear it when I'm not swimming too (you know, with clothes on).
