The Elite Bundle is Endorphin's running kit: the Endorphin Belt, two soft flasks (450 ml and 250 ml), and the Endorphin Performance Hat. The belt is the centerpiece, a 4.4 oz bounce-free belt with a waterproof phone pocket, dual-adjustment straps and gel loops. The two flasks fit the belt's front or rear pockets and combine for 700 ml of carry. It suits runners who want one race-day and training setup rather than buying belt, bottles and hat separately; the trade-off is that you pay for the hat and second flask whether or not you need them.

Rated 4.8 out of 5 across 993 ratings, buyers are largely enthusiastic about the belt's stability and the convenience of the full kit. Complaints center on the bundle format and capacity rather than the gear itself.
The Elite Bundle is a running kit that combines an Endorphin Belt, two soft flasks, an Endorphin Performance Hat and race bib toggles. It is meant for training, racing and daily runs, from mid-length to long distances.
The Endorphin Belt carries a phone, hydration and fuel. It has a waterproof phone pocket, gel loops and a dual-adjustment system that keeps it in place when fully loaded. It weighs 4.4 oz.
The two soft flasks are sized for the belt. They can be carried together for 700 ml of total capacity, or one at a time in the front or rear pocket. The hat is lightweight and breathable. The race bib toggles attach directly to the belt, so a race number can be secured without safety pins. The toggles are reusable.
