If you do carry a tea bag, you really need to consider how you will be boiling water to use it. <br><br>So the shirt pocket kit must be inclusive of at least a tin or foil to even have the option to make tea. Finding a tin can around an urban setting is easy enough, but a wilderness setting less likely. Brewing up in an Altoids tin seems hardly worth the effort for 3 oz of tea.<br><br>So if a tea bag is included in the PSK, so should a reasonable way to brew up.<br><br>I have a 600mL metal cup in my carry bag with tea bags. Comfort and calm provided by the ablity to brew up is worth the effort.<br><br>My PSK has one tea bag, no foil, in a plastic fly box....Why is it here? Hum...because it is my UERK...(urban emergency response kit)....Yea that's why.
