Just used my Camelbak for the first time today. Oh wow. Why didn't I do this sooner? DH wasn't thrilled, because he didn't have to stop for me to drink, and it was So Easy!!!! Water. On demand. What a novelty! I may look like a bit of a dork (most of the roadies around here are 'too cool' for a Camelbak), but I'm a hydrated dork with a happy husband. For that, I can live with being a dork! Best. Cycling. Accessory. Ever.
