The tradeoff is a bit more length and weight; if that's not a priority, the 88ci or 77ci will feel more compact on your marker.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"so-tab\"\u003e\n\u003cinput id=\"faq-aa98-4\" type=\"checkbox\" name=\"faq-aa98\"\u003e \u003clabel for=\"faq-aa98-4\"\u003eHow much more air does the 98ci hold than the 88ci?\u003c\/label\u003e\n\u003cdiv class=\"so-tab-content\"\u003e\n\u003cp\u003eThe 98ci holds about 11% more air than the 88ci, adding roughly 0.35in of length and about 2.7oz of weight — the smallest jump between any two sizes in the lineup, since it's the last step up to the largest bottle.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"so-tab\"\u003e\n\u003cinput id=\"faq-aa98-5\" type=\"checkbox\" name=\"faq-aa98\"\u003e \u003clabel for=\"faq-aa98-5\"\u003eWill my tank cover fit the 98ci?\u003c\/label\u003e\n\u003cdiv class=\"so-tab-content\"\u003e\n\u003cp\u003eThe 98ci keeps the same 4.4in diameter as every other Alpha Air bottle, so covers sized for that diameter will still fit around it.
