I would guess that each brand is slightly different, but if I am 6' 1", and most bags state a REG = up to 72" (6' 0") would I still "fit" in it or would that be so pussing the limit that it is not worth taking a change and just go with the LONG?
Anyone had any experience?
And I am tossing around either the Sierra Designs DriDown Cal 13 or the Marmot Helium Membrain SB if anyone has any opinions/experience.
