The humble sports cap has become a mainstay in thru-hiker packs for a reason - this plastic free flow sports cap allows for easy drinking on the go and can attach to any bottle with a 28mm thread, like our 28mm Vesica and Hydriams. Sold individually so there's no need to purchase a single use plastic bottle to grab one the next time yours gets lost or breaks.
Note: each purchase of a 28mm Vesica comes with a free sports cap
