Sea to Summit Frontier Ultralight Collapsible Pour Over

The Sea to Summit Frontier Ultralight Collapsible Pour Over is a fold-flat, single-serve pour-over coffee brewer built for backpackers, campers, and overlanders who want a proper cup of coffee without the bulk. The filter unit collapses into its polypropylene mount base, with a packed size of 4 × 4 × 1 in (10.6 × 10.6 × 1.4 cm), and pops open in seconds to brew directly into a mug or wide-mouth bottle.

A Real Cup of Coffee, Anywhere

The Frontier Pour Over uses a super-fine 304 stainless steel mesh filter that holds coffee grounds in place while allowing the natural oils to pass through into the cup. Those oils carry much of coffee's body and flavor, which is why paper-filter methods often taste thinner by comparison. The filter is molded permanently into the folding silicone pyramid, so there are no loose parts to lose on the trail and no paper filters to pack in or pack out.

Designed to Pack and Clean Easily

When brewing is done, the filter unit slides back inside the mount base, reducing the whole brewer to a 1-inch-tall disc that weighs 2.0 oz (55.7 g). The silicone and stainless steel construction is dishwasher safe, and the open mesh design rinses clean quickly in the field. The collapsed unit fits inside a Frontier Collapsible Kettle, keeping the camp kitchen kit consolidated.

Food-Grade Materials, No Compromises

The silicone used in the Frontier Pour Over is BPA-free, non-PFAS, and certified to EU and FDA food-grade standards, the same standards applied across Sea to Summit's Frontier Camp Kitchen Collection, which received a 2023 Australian Good Design Award Gold for the line. The mount base is polypropylene; the filter is 304 stainless steel. No coatings, no plasticizers, nothing that needs replacing.

Specifications

Who This Is For and Isn't

The Frontier Ultralight Collapsible Pour Over suits backpackers, bike packers, and car campers who want a genuine pour-over brew in the field without carrying a dedicated brewer. The mount base fits most standard mugs and wide-mouth bottle rims, making it compatible with gear most campers already carry.

The Frontier Pour Over is sized for one serving only (approximately 30 g of ground coffee) and is not available in a larger format for vacuum flasks or multi-cup brewing. The stainless steel mesh filter is molded into the silicone body and cannot be removed or replaced separately.

Common Questions

Does the Frontier Pour Over fit a vacuum flask or travel mug?

The Frontier Ultralight Collapsible Pour Over is designed to fit most standard mug rims and wide-mouth bottle openings. A larger version sized for vacuum flasks is not available. The Frontier Pour Over is built to fit most standard mug rims and wide-mouth bottle openings, not the narrower openings of vacuum flasks.

Can the Frontier Pour Over go in the dishwasher?

The Frontier Ultralight Collapsible Pour Over is dishwasher safe and can be machine washed. The stainless steel mesh and food-grade silicone construction hold up to repeated dishwasher cycles, making cleanup straightforward at home between trips.

Is the stainless steel mesh filter removable?

The stainless steel mesh filter in the Frontier Ultralight Collapsible Pour Over is molded directly into the folding silicone pyramid and is not detachable. This keeps the part count low and eliminates the risk of losing a separate filter component in the field.

How much coffee does the Frontier Pour Over hold?

The Frontier Ultralight Collapsible Pour Over is sized for approximately 30 g of ground coffee, which yields one serving. The Frontier Pour Over is not designed for multi-cup brewing; campers needing more than one serving at a time would need to brew multiple rounds.
