This jacket is so comfortable that I forgot it was even on. The mesh back kept me from sweating and let me sit all the way back against my seat. There are quite a few straps so that you can adjust it to fit perfectly. Add to that some handy pockets in the front for keys and a knife and you have a winner. The only drawback (and a minor one at that) is that the pockets are fairly small and snug. It's hard to beat this PFD, especially at this great price!
