Frontier UL Collapsible Cup

Description

The Frontier UL Collapsible Cup represents Sea To Summit's latest evolution in portable drinkware, combining over a decade of design refinement into a remarkably compact solution. Engineered with glass-reinforced nylon 66 at the base, rim and center ring, it delivers superior stability and ergonomic grip compared to earlier iterations. The EU food-grade silicone rubber sidewalls compress to under 2cm, making it ideal for backpacking, camping or travel where space is precious. These cups nest efficiently, maximising packability without sacrificing functionality or durability.
