When the valve is open, the foam draws air in like a sponge — cells expand and pull air through the valve automatically.\n\n\u003cstrong\u003eInflation steps:\u003c\/strong\u003e\n1. Unroll the mat, valve open\n2. Wait 5-10 minutes — foam self-inflates to ~80% capacity\n3. Add 2-4 breaths of mouth air to dial in firmness\n4. Close valve\n\n\u003cstrong\u003eDeflation steps:\u003c\/strong\u003e\n1. Open valve fully (XPEL valve enables faster deflation)\n2. Press flat from foot end toward valve end\n3. Roll tightly (the contour shape allows tight rolls)\n4. Insert into stuff sack via the wide side-loading opening\n5. Compress stuff sack to expel remaining air\n\n\u003cstrong\u003eWhy \"self-inflating\" + breath:\u003c\/strong\u003e foam cells can only draw so much air before backpressure stops them.
