Not the best for actual on the bike use, but I could see carrying this to work and back in a pannier for at the desk hydration. Aside from breakage, glass dirnking vessels are hands down my favorite to use. Easy to clean, non-toxic, flavorless and resistant to holding the taste of today’s beverage for tomorrow, there are a lot of reasons to like glass. Plastic bottles don’t bother me on the bike, but on the job I just can’t handle them. Lifefactory has introduced the Straw Cap line of 16 and 22 oz silicone shielded glass bottles to go alongside their flip and screw cap versions. Screw or flip cap versions are available now, with the straw cap available in store this spring for roughly $25. I can see this on summer commuter’s desks already.
