Frontier Ultralight Collapsible Pour Over
Collapsible Pour-Over Coffee Filter · 55.7 g / 2.0 oz · Stainless Steel Mesh · Polypropylene Mount Base · Stows in Frontier Kettle
For backcountry baristas everywhere, the super-compact Frontier Ultralight Collapsible Pour Over makes a perfect cup of coffee every time. The Frontier Ultralight Collapsible Pour Over folds flat for storage in its polypropylene mount base, then pops out when needed to make a perfect pour-over brew. The easy-to-clean stainless steel mesh filter is sized just right for one serving (approx. 30g) of ground coffee and formed to hold the grounds but filter the coffee oils for a rich, satisfying cup of coffee. The mount base fits most mugs and wide-mouth bottle rims, and the EU food-grade silicone rubber and stainless steel filter unit slides inside the base for easy transport. It even stows nicely in a Frontier Collapsible Kettle.

55.7 g / 2.0 oz — the lightest Frontier UL product.

Pyramid folds flat (4 × 4 × 1 in packed) for ultra-compact storage.
SS Mesh Filter
Super-fine stainless steel mesh — holds grounds but lets the good oils through.

Holds 1 serving (~30g) of ground coffee per brew.
PP Mount Base

Stows in Kettle
Per STS — designed to fit inside the Frontier Collapsible Kettle for transport.
Polypropylene Mount Base (NEW MATERIAL IN FRONTIER LINE)
The Pour Over uses a Polypropylene (PP) mount base — a new material for the Frontier line:
Material split:
- 47% Silicone (the collapsible pyramid body)
- 24% 304 Stainless Steel (the mesh filter)
- 29% Polypropylene (NEW: the mount base)
What Polypropylene adds to the line:
- The other Frontier products use 100% silicone + aluminum + glass-filled nylon
- PP is a hard plastic (vs flexible silicone)
- Lightweight + rigid + food-safe
- Common in kitchen tools (spatulas, cutting boards)
- Heat-resistant to 100°C+ (boiling water safe)
Why PP for the mount base:
- Hard surface = stable platform for the pyramid
- Doesn't flex when coffee is poured
- Heat-tolerant (boiling water contact)
- Food-safe (no plasticizers)
- Lightweight (~16 g for the base)
Where the PP goes:
- The mount base "fits most mugs and wide-mouth bottle rims"
- The pyramid slides INTO the base for transport
- The base supports the pyramid when in use
Collapsible Pyramid (Folds Flat)
The pour over is a collapsible pyramid design:
Packed state (per STS):
- "Folds flat for storage in its polypropylene mount base"
- Packed size: 4 × 4 × 1 in (10.6 × 10.6 × 1.4 cm)
- = Incredibly compact (a credit-card-thick packet)
In use:
- "Pops out when needed to make a perfect pour-over brew"
- Open dimensions: 4 × 4 × 4 in (10.2 × 10.2 × 9.5 cm)
- Forms a pyramid shape for coffee brewing
Pyramid shape advantages:
- The shape is the classic pour-over cone
- Steam rises through the cone (cools + drips)
- Filter mesh holds grounds in the cone
- Coffee drips into the mug below
Filter design:
- "Super-fine stainless steel mesh to hold in grounds but let the good oils through"
- "Formed to hold the grounds but filter the coffee oils for a rich, satisfying cup of coffee"
- = Better than paper filters (no paper taste, more oils = better flavor)
Stows Inside the Frontier Kettle (NEW INTEGRATION)
Per STS: "It even stows nicely in a Frontier Collapsible Kettle."
What "stows nicely" means:
- The Pour Over's 4 × 4 × 1 in packed profile fits inside the Frontier Kettle (A1228)
- Or fits inside any small pot
- = One packed bundle for the morning coffee routine
Practical use:
- Wake up → pull out the Frontier Kettle
- Pull out the Pour Over (was inside the kettle)
- Set up the Pour Over on a mug
- Boil water in the kettle
- Pour water over the coffee grounds
- Wait for the coffee to drip through
- = One full brewing setup from a single packed bundle
Per FAQ: "We don't - the Frontier pour over is designed to fit into our smallest pots/kettles"
- The Pour Over is intentionally small
- Maximizes portability
- "Designed to fit into our smallest pots/kettles"
DISHWASHER SAFE (DIFFERENT FROM OTHER FRONTIER PRODUCTS)
Per STS FAQ: "Is the pour over dishwasher safe? Yes - it can be washed in a dishwasher."
This is a DIFFERENT answer from other Frontier products!Why the difference:
- The Frontier pots/kettles have hard-anodized aluminum (damaged by dishwasher)
- The Pour Over has NO aluminum — just silicone + 304 SS + PP
- = No anodization to damage
- = Dishwasher-safe
Material split:
- 47% Silicone (heat-tolerant, dishwasher-safe)
- 24% 304 Stainless Steel (dishwasher-safe)
- 29% Polypropylene (dishwasher-safe to 100°C+)
All 3 materials are dishwasher-tolerant:
- Silicone: ~230°C+ tolerance
- Stainless steel: dishwasher cycles are fine
- Polypropylene: ~120-130°C tolerance (well above dishwasher temps)
Practical:
- Throw the Pour Over in the dishwasher with your other kitchen gear
- No special hand-wash protocol
- More convenient than the Frontier pots/kettles
Award-Worthy Backcountry Barista Tool
Per STS: "For backcountry baristas everywhere"
The positioning:
- For people who want real coffee on trail
- Not instant coffee / freeze-dried
- Pour-over = the craft method
- "Backcountry barista" = the serious coffee drinker in the outdoors
Why pour-over for backpacking:
- Better than instant (real coffee experience)
- Lighter than French press (no metal frame)
- Lighter than Aeropress (no plastic body)
- Better than percolator (no metal parts to clean)
- 2 oz for a real coffee setup = no compromise
What "30g of grounds" means:
- 1 serving = 1 standard cup of coffee
- Per STS FAQ: filter is "sized just right for one serving"
- Multiple brews = need more grounds
- But 1 serving per brew = perfect single-person setup

DISHWASHER SAFE (The Only Frontier Product That Is!)
Per STS FAQ: "Is the pour over dishwasher safe? Yes - it can be washed in a dishwasher."
This is the OPPOSITE of the other Frontier products:
- Other Frontier: NOT dishwasher safe (anodized aluminum)
- This Pour Over: DISHWASHER SAFE (no aluminum)
- = Different material set = different care
Why the difference:
- The Pour Over has NO anodized aluminum to damage
- Material split: 47% silicone + 24% 304 SS + 29% PP
- All 3 materials are dishwasher-tolerant
- Throw it in the dishwasher with your other dishes
Materials & dishwasher tolerance:
- Silicone: ~230°C+ tolerance
- 304 SS: dishwasher cycles are fine
- Polypropylene: ~120°C tolerance (well above dishwasher temps)
Practical:
- Throw in the dishwasher after a trip
- No special hand-wash protocol
- More convenient than the Frontier pots/kettles
- Use the dishwasher for any cooked coffee residue
Stainless Steel Mesh Filter Care
The mesh filter is the key feature — take care of it:Cleaning:
- Rinse immediately after use (prevents coffee oils from drying)
- Mild soap + warm water
- Soft brush to remove grounds (a small bottle brush works)
- The mesh is fine — don't use abrasive scrubbers (degrades the mesh)
- Dishwasher safe (per FAQ)
Longevity:
- 304 SS won't rust
- Fine mesh stays effective for years
- Coffee oils can build up over time → strip with baking soda
If the mesh gets damaged:
- The filter is molded into the pyramid (per FAQ: "No - it is molded into the folding 'pyramid'")
- = Can't replace the mesh alone
- = Need to replace the whole Pour Over if the mesh is damaged
- STS sells spares or replacements
Pro tip:
- After each use, rinse thoroughly
- The oils in coffee can build up
- Use a small bottle brush for the mesh
- Or soak in mild soap + water
Polypropylene Mount Base Care
The Polypropylene mount base is rigid and durable:
Care:
- Wipe with damp cloth after use
- Dishwasher safe
- The PP material is heat-tolerant
- Don't put in direct flame (degrades PP)
Why PP is good for the mount base:
- Rigid = stable platform for the pyramid
- Doesn't flex when coffee is poured
- Heat-resistant
- Lightweight
The mount base function:
- "Fits most mugs and wide-mouth bottle rims"
- Wide compatibility (most standard cups)
- For smaller mugs, the base hangs over the edge
- For wide-mouth bottles, the base sits on the rim
Practical:
- Hot mug + cool base = no melting
- Dishwasher cycles are fine
- Long-life (PP is durable)
Avoid These Failure Modes
Don't:
- Microwave (PP + metal = bad)
- Force the pyramid open (degrades the silicone hinge)
- Cut with sharp objects (silicone damage)
- Use with non-mug containers (won't fit)
- Use if the mesh is damaged (coffee grounds in the cup)
- Drop on hard surfaces (silicon + PP can crack)
- Store wet for extended periods (potential mildew)
Common failure points:
- Mesh filter damage (cut by utensils or rocks)
- Pyramid hinge stress (over-folding)
- Mount base cracking (extreme cold + impact)
- Lost in the field (it's small — keep track of it!)
Sustainability & End-of-Life
Material considerations:
- Silicone: harder to recycle (specialty facilities)
- 304 stainless steel: highly recyclable
- Polypropylene: recyclable (code 5)
Longevity factors:
- Stainless steel mesh: years of use
- Silicone pyramid: 20+ years
- Polypropylene base: very durable
- Total expected life: 5-10+ years
At end-of-life:
- SS mesh: recyclable as scrap metal
- PP base: code 5 recycling (some facilities)
- Silicone: landfill mostly
Compare to the other Frontier products:
- Frontier pots/kettles: NOT dishwasher safe (anodized aluminum)
- This Pour Over: IS dishwasher safe (different materials)
- = The Pour Over is the more convenient-care coffee accessory
Activity-Specific Tips
- Backcountry barista (primary): Real pour-over coffee on trail. 2 oz for the whole setup.
- Bikepacking: Stows in handlebar roll. Brew at cafe stops or camp.
- Packrafting: 2 oz is negligible. Brew during lunch stops.
- Solo thru-hiking: Combine with Frontier Kettle — full coffee routine from a single packed bundle.
- Most important: Dishwasher safe = easy cleanup. Hand-wash not required.
