Size Comparison (2 Sizes)
304 Stainless Steel + EU Food-Grade Silicone (NEW — MATERIALS)
The Detour Collapsible Bowl uses a 77% Stainless Steel / 23% Silicone material split — combining the rigidity of steel with the flexibility of silicone.
304 Stainless Steel:
- Industry-standard food-grade stainless steel
- Same alloy used in cookware, water bottles, restaurant equipment
- Corrosion-resistant, durable, doesn't impart flavors
- Won't bend or flex — feels like real dinnerware even when expanded
- Easy to clean, dishwasher-safe
- Better heat tolerance than aluminum (won't leach flavors at high temps)
EU Food-Grade Silicone:
- Higher regulatory standard than basic "food-grade" claims
- Free of BPA, PFOA, PTFE — verified per EU safety standards
- Heat-resistant up to high temperatures (vs plastic which can warp)
- Flexible enough to fold the bowl flat
- Doesn't absorb odors or flavors
- Backed by EU food-contact certification
Why this combo:
- Steel provides structure and rigidity (real-bowl feel)
- Silicone provides the fold mechanism (the hinge that lets it collapse)
- Together they create a bowl that's both rigid in use and collapsible in storage
- 23% silicone is engineered to be the minimum needed for the folding seam while keeping the bowl mostly rigid
Collapse Mechanism (HOW IT WORKS)
The bowl collapses from 5.1 cm (M) or 4.8 cm (L) open to a 2.1 cm (21mm) flat disc for storage. Here's how:
Collapsing (storage):
1. Press the sidewalls toward the center
2. The silicone hinge folds inward
3. Bowl flattens to 21 mm height
4. Stacks flat against other Detour pieces
Expanding (use):
1. Press flat plate-like bowl on table
2. Pull sidewalls up and outward
3. Sidewalls click into rigid position (steel structure holds shape)
4. Bowl is ready to use
Why this is better than soft silicone-only collapsibles:
- Soft silicone bowls flop around, slosh when held
- Steel-reinforced Detour bowls hold their shape like ceramic/steel dinnerware
- More pleasant to eat from, easier to scoop from
The hinge: the silicone runs in a single seam around the bowl's circumference. That seam is the only moving part. Steel sidewalls stay rigid; silicone hinge flexes.
Silicone Base Insert — No-Rattle Design (NEW — DETAIL)
The base has a silicone rubber insert that solves two common problems with collapsible bowls:
No Sliding:
- Silicone grips smooth surfaces (table, counter, shelf)
- Bowl stays put when eating in motion (RV, boat, train)
- Important for people who eat in unstable environments
No Rattle:
- Without silicone, steel bowls would clang against each other in storage
- Silicone absorbs vibrations — folded bowls are silent in a pack or cabinet
- Critical for RV/boat dwellers (per STS FAQ)
Bonus: Heat Insulation:
- The silicone insert also insulates your hand from hot contents
- STS confirms the bowl "can be held comfortably when it contains hot food"
- The silicone doesn't get as hot as the steel walls would
Spoon-Matched Curve (DESIGN)
The inside curve between the base and sidewalls is engineered to match Sea to Summit spoons — this is the same radius as the spoon bowl.
Why this matters:
- Spoon tip matches the curve — easy to scrape the last yogurt, soup, oatmeal
- Reduces food waste (no un-scooped residue in corners)
- Easier cleanup (smooth, no tight corners to scrub)
- More pleasant eating experience
STS spoons that fit:
- Folding Camp Spatula & Serving Spoon (from Camp Kitchen Tool Kit)
- Detour spoons (sibling dinnerware)
- Frontier UL Cutlery (3-piece + Long Handle 2-piece)
Practical difference: vs generic bowls with sharp 90° angles (where spoons can't reach corners), the Detour's curve means you actually finish your meal cleanly.
Stackable Design (for Transport)
Multiple Detour Bowls (and Plates, Mugs) stack flat when collapsed:
Why stacking matters:
- Packed flat (21mm) bowls nest tightly
- Stack 4-6 bowls in the same space as 1 unfolded bowl
- Fits easily in RV cabinet, kitchen drawer, or pack side-pocket
- Doesn't waste pack real estate
STS dinnerware ecosystem:
- Detour Stainless Steel Bowl (this product)
- Detour Stainless Steel Plate (sibling)
- Detour Stainless Steel Mug (sibling)
- All use the same collapse-to-flat mechanism
- All stack together when packed
Family setup: 4 people + 4 bowls + 4 mugs + 4 plates = single stack under 5 cm tall.
Hot Content Advisory (NEW — IMPORTANT)
Per STS: "Please be aware that this product may become hot when used with hot contents. Handle and use with caution."
What this means:
- The steel walls conduct heat
- Hot contents will heat the bowl — like any metal bowl
- The silicone base insert provides some insulation but not full
- Use a bowl holder, pot holder, or wait for the bowl to cool slightly
Practical tips:
- For very hot soups/stews, let the bowl cool briefly before handling
- Or wrap the bottom in a bandana/cloth
- The silicone base insert insulates somewhat but not completely
- Heat tolerance is actually a benefit (no plastic warp at high temps)
Why metal conducts heat:
- Stainless steel is a fair heat conductor (vs silicone, plastic, ceramic which insulate)
- Hot soup warms the steel walls
- This is true of all-metal bowls including ceramic-coated metal
Don't confuse with:
- The bowl is heat-tolerant (won't deform or melt)
- But the OUTSIDE will be hot when contents are hot
- Handle accordingly
Award-Winning Design (NEW)
The Detour Collapsible Bowl is Award Winning per STS tags — recognized by industry design awards for innovation in collapsible dinnerware.
Why it won:
- "From the inventors of collapsible dinnerware" — STS pioneered the collapsible category
- New stainless + silicone combo is genuinely innovative
- Solves real durability problem (soft silicone collapsible bowls wear fast)
- Maintains the form factor people love
- Improves longevity significantly

Sustainability
304 Stainless Steel is highly recyclable; durable construction extends product life; silicone insert is replaceable
Dishwasher Use
Yes, dishwasher safe per STS FAQ.
Care tips for dishwashing:
- Top rack recommended (less heat exposure)
- Standard dishwasher detergent works
- Avoid harsh detergents that could affect silicone over time
- The 304 stainless steel tolerates high heat well
- The silicone hinge tolerates dishwasher temperatures
- Dry thoroughly before folding for storage (no trapped moisture in the silicone seam)
Hand-washing alternative:
- Mild soap + warm water
- Soft cloth or sponge
- Easy to clean (smooth surfaces)
- Quick dry
Both methods work — dishwasher for convenience, hand-wash for longest life.
Hot Content Handling
Per STS advisory: "Please be aware that this product may become hot when used with hot contents. Handle and use with caution."
Safe hot-content practices:
- Wait briefly before handling very hot foods (let the bowl cool slightly)
- Hold by the silicone base when possible (somewhat insulating)
- Use a cloth or pot holder for piping-hot soups/stews
- Don't microwave (metal — sparks/damage)
- Don't expose to open flame (silicone may discolour or degrade)
Heat limits:
- 304 stainless steel: tolerates high heat (won't deform)
- Food-grade silicone: heat-tolerant, but prolonged open-flame exposure may degrade
- Bowl is designed to hold hot food, not to be heated directly
Stainless Steel Care
304 Stainless Steel is one of the easiest materials to maintain:
Routine care:
- Wash with soap and water after use
- Dishwasher safe (top rack preferred)
- Dry promptly to avoid water spots (cosmetic, not functional)
- For shine, buff with a soft cloth
Stain removal:
- For tough spots, use a stainless steel cleaner (Bar Keepers Friend is classic)
- Or use baking soda + water paste
- Avoid steel wool (scratches the surface)
- Avoid bleach (can pit the surface over time)
Preventing rust (rare with 304 SS):
- 304 SS is highly corrosion-resistant
- Dry before long-term storage in damp conditions
- If surface rust appears (very rare), scrub with stainless cleaner
- Don't store wet
Silicone Hinge Care
The silicone hinge is the only moving part — care matters here.
Cleaning the hinge:
- Open the bowl fully to expose the silicone seam
- Wipe with soapy water + cloth
- For stuck food, soak briefly in warm soapy water, then wipe
- Don't use abrasive cleaners on silicone (can roughen the surface)
- Make sure no food is trapped before folding for storage
Avoid:
- Sharp objects (knives, forks) against the silicone seam — can cut/tear
- Excessive force when expanding/collapsing
- High-concentration bleach (can degrade silicone over time)
- Punctures from utensils
Silicone replacement:
- If the silicone ever tears, contact STS for replacement parts
- Most users never tear it (304 steel protects the structure)
- With normal use, the silicone lasts the lifetime of the bowl
Collapsing & Storage Best Practices
Always collapse clean and dry:
- Wash and dry before folding
- Trapped moisture in the hinge = mildew risk
- Trapped food = stains + odors over time
Storage orientation:
- Lay flat (collapsed) in a kitchen drawer or cabinet
- Stack multiple bowls for space efficiency
- The silicone insert keeps them from sliding/rattling in storage
Long-term storage:
- Cool, dry place
- Out of direct sunlight (UV can affect silicone over years)
- If stored in a vehicle, expect temperature swings (silicone tolerates them)
Re-expanding:
- Pull the sidewalls up and outward
- The bowl "clicks" into rigid position
- The steel structure holds the shape
- If it doesn't click fully, check for food/obstruction in the hinge
Avoid These Failure Modes
Don't:
- Microwave (it's metal — sparks, damage)
- Expose to open flame
- Cut against the silicone with sharp utensils
- Force the bowl closed (designed to fold one way only)
- Use harsh abrasives on either surface
- Store wet or with food trapped in the hinge
- Stack heavy items on top (deforms steel over time)
If dropped:
- 304 steel resists denting but extreme impact could deform
- Check the hinge is still flexible after a drop
- The bowl will still work even if slightly dented
If the silicone tears:
- Stop using immediately (food can get trapped in the tear)
- Contact STS for replacement parts
- Don't try to glue (food-contact glues are limited)
Sustainability & End-of-Life
304 Stainless Steel is one of the most recyclable materials:
- Recyclable indefinitely without property loss
- Most metal recyclers accept
- High scrap value — easy to recycle properly
Silicone is harder to recycle but:
- Durable (lasts the lifetime of the bowl)
- Replaceable if damaged (STS support)
- Some specialty recyclers accept silicone
Longevity:
- With normal use and care, the Detour Bowl lasts 10+ years
- Stainless steel doesn't wear out functionally
- Silicone may need replacement after very heavy use but is durable
At end-of-life:
- Separate steel from silicone (cut the silicone seam)
- Recycle the steel at scrap metal
- Silicone to specialty recycler or landfill
- Or donate if still functional
Activity-Specific Tips
- Van life / Overlanding: Ideal primary use. Silicone base insert prevents rattle (key for long drives). Stack with other Detour pieces. Use as everyday dinnerware.
- Auto camping: Stack for transport. Use real-dinnerware feel at the campsite. Dishwashable when you get home.
- Boat / Yacht: No-rattle design is critical. Stainless steel tolerates marine environments. Silicone base grips boat counters in motion.
- Family camping: L size for adults, M size for kids. Buy 4 of each for the family. Stack for transport.
- Hunting cabin: Durable for rough use. Dishwasher-safe for easy cleanup. Stack for storage in the cabin.
- Cabin / Vacation Rental: Bring your own dinnerware for hygiene. Detour packs flat in luggage.
- Daily Office Lunch: Collapses for bag, expands to real bowl eating. More pleasant than plastic containers.
- Road trips: Stack in glove box or center console. Avoid fast-food bowls — use real dinnerware at rest stops.
- NOT for backpacking — too heavy (vs Frontier UL at ~50 g).
