So, is it any good?

The kettle collapses to under two inches tall, the flattest packing item in this group.

The whole set weighs about 11.2 oz including two cups.

It flattens down to almost nothing and boils fast on my stove, but I keep it well away from any open flame and do not expect to fry in it.

Our Analysis, Comparisons, and Test Results

The Sea to Summit Frontier Ultralight Collapsible Set scored 86 out of 100 overall.

It is strongest on packability and weakest on ease of use.

Here is how it did on every metric we tested, with exactly how each score compares to the rest of the field.

Cooking Performance

The hard anodized aluminum base transfers heat fast and boils two cups of water in about five minutes.

The wide rim lets the kettle work as a shallow cooking pot as well.

The silicone walls mean it is not ideal for open flame, so it suits a stove.

It is aimed at boiling water more than frying or simmering real meals.

Packability

The kettle collapses to under two inches tall, the flattest packing item in this group.

The whole set weighs about 11.2 oz including two cups.

But here is the catch:

It flattens into a pack far better than a rigid pot.

PackabilityRating

Durability

The kettle uses EU food grade silicone paired with a hard anodized aluminum base.

Reviewers call the build quality top notch with no early failures reported.

The silicone body resists dents that would dip a thin metal pot.

The aluminum base is the part exposed to heat, so keep it off open flame.

Weight

At about 11.2 oz the full kettle and two cups make a light two person kit.

The collapsible design saves both weight and pack volume.

Light enough for fast and light backpacking.

Ease of Use

Two glass reinforced nylon handles give a stable pour.

The silicone insulates enough to hold on a cold morning like a hand warmer.

You must expand it fully before heating, an extra step over a rigid pot.

Features

The wide rim lets it double as a cook pot when needed.

The pour handles make it a genuine kettle, not just a pot.

What Other Camping Cookware Sets Should You Consider?

Not sold on this one? A few others from our testing are worth a look.

The GSI Halulite Minimalist Cookset is our best aluminum backpacking pot. A tiny, cheap and very light solo boil water pot, ideal for dehydrated meals but too small to actually cook in.

The Snow Peak Titanium Multi Compact Cookset is our best titanium cookware. The lightest and toughest option here, but titanium hot spots make it a boil water pot more than a cooking pot.

The GSI Halulite MicroDualist 2-Person Cookset is our best backpacking cookware. A smart two person backpacking kit that cooks, eats and packs well for close to titanium performance at a lower price.
