Sea to Summit Frontier Ultralight Collapsible Cup

The Sea to Summit Frontier Ultralight Collapsible Cup is a masterclass in minimalist outdoor design, engineered for backpackers, hikers, and ultralight campers who demand maximum performance with minimal bulk. Crafted with food-grade, heat-resistant silicone walls and rigid heat-shielding rings and base made of glass-reinforced nylon66, this cup magically collapses to under 2cm in height, folding flat to nest into any corner of your pack or even slip into your pocket.Despite its compact form, it offers a practical capacity of around 355ml (some sources round this to 400ml), and weighs a mere 54g.

The materials are BPA-free and meet EU/FDA food-grade standards; the silicone walls withstand temperatures up to 150C without cracking, while the nylon components provide durable reinforcement-even through thousands of collapses.It also nests neatly with other Frontier Cookware, such as the 2L Pouring Pot, adding to its modular versatility.However, keep in mind it lacks insulating power - its silicone walls do temper heat slightly, but it isn't a substitute for double-walled insulated mugsv- and microwaving is not recommended.

Features:

1. Ultra-Lightweight: Weighs just about 54g , making it one of the lightest collapsible cups available.
2. Compact Collapsed Size: Collapses to under 2cm (around 17-20mm) thick, so it easily fits in a pocket or slim portion of your pack.
3. Mixed Material Build: Sidewalls are crafted from food-grade, BPA-free silicone, while the base, rim, and center ring are reinforced with glass-reinforced nylon 66 for structure and heat protection.
4. Heat Shielding Design: The nylon rings help insulate and protect fingertips from hot contents.
5. Ample Volume: Holds around 355ml to 400ml (12-13.5oz), sufficient for a standard serving of hot beverage or hydration on the trail.
6. Nesting Compatibility: Designed to nest with other Frontier series dinnerware, including the 2L Pouring Pot-great for organized packing.
7. Dishwasher Safe & Durable: Made to withstand regular dishwashing and tested to endure 5,000 cycles of collapsing/expanding without failure.

Product Care:
1. First Use: Wash with warm, soapy water and dry thoroughly before using it for the first time.
2. Avoid Harsh Tools: Do not use heavy-duty scouring pads, as these may damage the silicone.
3. Rinse & Dry: Always rinse well and dry completely before storing.
