A neoprene sleeve that carries a 1000 ml (33.8 oz) bottle on a shoulder strap and leaves both hands free.
The neoprene is 0.45 cm thick and does two jobs with that thickness: it slows a cold drink warming and a hot one cooling, and it puts a layer between your palm and a single-wall aluminium or steel bottle that has been standing in the sun. It also absorbs the knocks that dent a bare bottle on a rock or a kerb.
The sleeve is about 8 cm across and 20 cm tall, and fits most 1000 ml bottles measuring roughly 3 x 23 cm. The strap adjusts up to about 110 cm, long enough to wear crossbody on a hike or around town. Black; the bottle is not included.
