Planning some touring for next year and am thinking about getting a hydration pack. Had a minimalist Camelback about 10 years ago and didn't like riding with the bladder more than 1/2 full as became an uncomfortable lump on my spine. The bladder didn't contain any baffles and I see a lot of the new packs have this.
Anyone else have this issue? Are packs with baffles in them noticeably more comfortable?
