Sea to Summit Frontier Ultralight Collapsible Kettle

The Sea to Summit Frontier Ultralight Collapsible Kettle is a 1.1L silicone-and-aluminum kettle that collapses to a 6 × 6 × 2 in pack footprint and weighs 7.1 oz, built for backpackers and camp cooks who need boiling water without sacrificing meaningful pack space. The body is EU food-grade silicone rated to 225°C / 440°F, the base and lid are hard anodized aluminum, and the construction is BPA-free and non-PFAS.

Collapses Flat, Boils Fast

At 7.1 oz and a packed size of 6 × 6 × 2 in, the Frontier Kettle fits into gaps in a pack that a rigid pot cannot. Hard anodized aluminum on the base distributes heat evenly and avoids hot spots, so water comes to temperature quickly on a canister stove or a two-burner camp stove. Keep the flame pattern within the printed ring on the base and the handles in the vertical position during use. When the trip is over, the kettle collapses back down in seconds and takes up almost no room in a dry bag or kitchen roll.

One Piece That Does Two Jobs

The Frontier Kettle's wide rim lets it function as a small cookpot when the situation calls for it: heating soup, rehydrating a meal, or simmering anything that fits in 1.1L. Dual glass reinforced nylon handles give a stable, controlled pour even when the kettle is full, and the silicone lid grip stays cool enough to handle without a cloth. Carrying one piece of cookware that covers both boiling and light cooking reduces total kit weight and frees up space for other gear.

Materials Built for Repeated Use

The silicone body is EU food-grade certified and heat resistant to 225°C / 440°F, and it does not crack in cold temperatures. That cold-weather resilience is relevant for alpine starts or winter camping where gear sees wide temperature swings in a single day. The hard anodized aluminum base and lid resist surface damage through the anodization process. The entire kettle is BPA-free and non-PFAS, meeting US, EU, Japan, and South Korea food-grade standards. Sea to Summit backs the Frontier Kettle with a lifetime guarantee.
