The updated Nathan Speed 4R now features 4 soft-squeeze 8 oz flasks with silicone Race Caps that are always open, but don't leak. A stretch belt with velcro closure makes fit-adjustments easy on-the-run and an open mesh pocket stashes several gels and keys, or your iPhone; a small front water-resistant velcro pocket keeps electrolyte caps within easy reach.
