Sea to Summit Frontier Ultralight Collapsible Bowl

The Sea to Summit Frontier Ultralight Collapsible Bowl is a packable camp and backpacking bowl built from EU food-grade glass-reinforced nylon 66 (base and rim) and food-grade silicone rubber (sidewalls), collapsing to under 2 cm for minimal pack footprint. The bowl is available in Medium (680 ml) and Large (887 ml), each in Puffins Bill and Aqua Sea colorways.

Collapses Flat Without Sacrificing Capacity

The Frontier Ultralight Collapsible Bowl flattens to under 2 cm when not in use, so it slips into a pack pocket or cook kit without claiming meaningful space. At 62 g for the Medium and 82 g for the Large, the bowl adds almost nothing to a base weight. For backpackers and overlanders who count grams and cubic centimeters, that combination of low weight and flat packed profile means the bowl is always worth bringing rather than leaving behind.

Built to Last Through Thousands of Uses

The base and rim of the Frontier Bowl are molded from glass-reinforced nylon 66, a material stiff enough to hold its shape under a full load of food and rigid enough to grip comfortably. The silicone sidewalls are heat resistant to 150°C / 300°F and tested not to crack in cold temperatures. Each bowl is cycle-tested on a mechanical rig through 5,000 extend-and-collapse repetitions before release, so the collapsing mechanism is not a weak point. Sea to Summit backs the bowl with a lifetime guarantee.

Designed to Work With Sea to Summit Spoons and Cookware

The curve where the sidewalls meet the base is shaped to match Sea to Summit spoons, so the spoon sweeps cleanly around the interior without leaving food in the corners. The Medium bowl is sized and shaped to nest inside the Sea to Summit Frontier 2L Collapsible Pouring Pot, keeping the cook kit compact when packed together. The Frontier Camp Kitchen Collection, of which this bowl is part, received a Gold award at the 2023 Australian Good Design Awards, recognized by the World Design Organization as Australia's peak international design endorsement program.

Specifications

Who This Is For and Isn't

The Frontier Ultralight Collapsible Bowl suits backpackers, bikepacking travelers, and overlanders who want a durable, packable eating bowl that weighs under 90 g and packs nearly flat. The Medium size works particularly well for anyone already running Sea to Summit Frontier cookware, as it nests directly inside the Frontier 2L Collapsible Pouring Pot.

The Frontier Bowl does not include a lid, and no press-fit lid is available for it. Neither size is microwave safe. The Large bowl does not nest inside the Frontier 2L Collapsible Pouring Pot; only the Medium does.

Common Questions

Can the Frontier Ultralight Collapsible Bowl be used in a microwave?

The Sea to Summit Frontier Ultralight Collapsible Bowl is not microwave safe and should not be used in a microwave oven. For reheating food, transfer contents to a microwave-safe container before heating.

Is the Frontier Bowl dishwasher safe?

Yes, the Sea to Summit Frontier Ultralight Collapsible Bowl is dishwasher safe and can be cleaned in a standard dishwasher at home or in camp facilities that offer dishwasher service.

How durable is the collapsing mechanism?

The Sea to Summit Frontier Ultralight Collapsible Bowl is cycle-tested on a mechanical rig through 5,000 extend-and-collapse repetitions. The base and rim are glass-reinforced nylon 66, which resists deformation under load, while the silicone sidewalls are rated not to crack in cold temperatures.

Is a lid available for the Frontier Bowl?

No lid is available for the Sea to Summit Frontier Ultralight Collapsible Bowl. Sea to Summit does not offer a press-fit lid for this bowl due to safety concerns associated with press-fit closures on collapsible vessels.

Does the Frontier Bowl nest inside Sea to Summit cookware?

The Medium Frontier Ultralight Collapsible Bowl (680 ml) is designed to nest inside the Sea to Summit Frontier 2L Collapsible Pouring Pot. The Large bowl (887 ml) does not nest inside that pot; nesting compatibility for the Large size with other Frontier cookware is not specified.

Sea to Summit offers its Guarantee for the lifetime of the Frontier Ultralight Collapsible Bowl. For specific terms and the claims process, refer to Sea to Summit's guarantee documentation at the time of purchase.
