SG-Fieldcore Floatant Holders are available in three sizes. While they fit a wide range of floatant brands, we designed them around some specific bottles that we know a lot of y'all (including us!) like to use. Here are some reference points to decide which holder you need: "Small" was designed around the Loon Lochsa and Gink "Medium" was designed around the Tiemco Shimazaki Dry Shake "Large" was designed around the Loon Top Ride The mil-spec woven elastic we use to construct the holders will stretch around larger bottles without losing elasticity but use the references above to get the best fit. Key Features Velcro-hook backing to position anywhere inside the main compartment of the Frontier Chest Pack or on a MOLLE Velcro Panel on the front of the pack. Comes with a silicone drying band installed (assorted colors) Made in USA (Floatant bottles shown are for demonstration only and are not included.)
