Sea To Summit Collapsible X Cup 250ml

Sea To Summit Collapsible X Cups are an ideal weight and space saving drinking vessel for adventurers.

Manufactured from food grade BPA free heat resistant silicone, these cups walls have a concertinaed design that allows them to fold flat when not in use to a disc that has a depth of only 15mm.

When extended, the durable Nylon 66 rim provides extra support to prevent the opening from collapsing, allowing you to drink hot and cold drinks safely. On the inner walls there are calibrated imperial and metric measuring marks enabling it to be used as a measuring cup.

With a holding capacity of 250ml, these X Cups are compact enough to be stored in pockets for quick access when thirsty.
