Per STS FAQ: "Inflating an Ether Light will take 20+ breaths (depending on lung capacity). Whereas using the integrated pumpsack reduces this to three or four breaths." Inflation tips: - Use the integrated pump sack (much faster than mouth) - Inflate to medium firmness first, then adjust - For 3-season use, slightly under-inflate (more comfortable, less sweating) - For 4-season/winter use, fully inflate (more insulation = more air) - Add a few breaths after 30 min in the tent (foam creeps, may need top-up) Deflation tips: - Open XPRESS valve fully (large open position) - Press air out from foot end toward valve - Roll tightly for packing - Some residual air leaves slowly (leave valve open during packing) - Don't force the valve (open gently, wait for air to leave) Common mistakes: - Closing valve too early (mat inflates more from body heat — can over-inflate) - Too much force on the valve (damages the seal) - Inflate in the rain (water inside the pump can get into the mat)

The PillowLock patches grippy surface needs occasional care: Cleaning: - Wipe with damp cloth (no soap needed) - Don't use fabric softener (coats the grippy texture) - Don't scrub with abrasives (removes the grippy coating) Effectiveness: - Pure silicone-based patches grip best when clean - After many trips, grip may reduce (oil buildup from body contact) - Hand-wash in mild soap, rinse well - Air dry fully before packing Replacement: - Replaceable patches if needed - STS sells replacement patches - Apply to clean, dry mat surface

STS includes a repair kit with every mat — be familiar with it before you need it: Common field damage: - Pinhole leaks (small) - Larger punctures (thorns, rocks) - Valve issues (slow leak) - Seam failures (rare with newer welds) Repair process: 1. Identify the leak (inflate + listen + soap test) 2. Clean the area with alcohol wipe (included in kit) 3. Apply patch (included in kit) 4. Wait 24 hours for adhesive to cure 5. Re-inflate For serious damage: - Patch in the field as best you can - Sleep on it (foam creeps help with support) - Send for warranty repair after the trip

The ThermalCore / TRM (Thermal Reflective Membrane) is delicate: Avoid: - Folding the mat (compresses the TRM layers over time) - High heat (melts the TRM layers) - Direct sunlight for long periods (UV degrades TRM) - Sharp folding (creases damage the layers) Storage: - Store loosely (rolled loosely, not folded) - Don't store compressed for months - Avoid storing rolled tight - Room temperature (not hot car trunks) Inflation cycle benefit: - Repeated inflation creates a slight air gap - Helps the TRM layers not stick together - Use the mat regularly to maintain loft

Between trips: - Clean and dry before storing - Deflate fully - Loosely roll (not tight compression) - Store in stuff sack or loose - Room temperature - Avoid moisture (mildew risk on nylon) Long-term storage (months): - Don't store compressed tightly in the stuff sack - The compression damages air cell structure + insulation - Spread out flat in a closet if possible - Or loosely fold in a large container Inflated storage (alternative): - Leave inflated for long-term - Like a permanent spare bed (for guests, etc.) - Saves compression cycles

Don't: - Inflate mouth if pump is available (lots of moisture + slow) - Over-inflate (strains welds) - Use as a flotation device (not designed for that) - Leave in direct sunlight for hours (UV damages TRM) - Store compressed for months - Sleep on sharp objects (rocks, sticks, pine cones) - Use harsh chemicals on the face fabric - Wash in a top-loader (agitator damages welds) If damaged in field: - Small hole: patch from repair kit - Larger hole: emergency patch with Tenacious Tape - Major damage: field repair + warranty after If the mat won't stay inflated: - Check the valve (often the culprit) - Then check for leaks (soapy water test) - Then apply patch - Then contact STS warranty

Non-PFAS + flame-retardant free: - Per FAQ: "All Sea to Summit sleep products (pads, sleeping bags, liners and pillows) are non-PFAS and flame-retardant free" - No forever-chemical concerns Longevity: - 5-10 years with proper care - Welds are the most likely wear point - TRM layers last the life of the pad if not damaged At end-of-life: - TPU/nylon can be specialty-recycled - Don't landfill (long decomposition) - Some textile recyclers accept inflatable mats Repair culture: - Patches extend life by years - Replaceable welds for major damage - STS supports warranty repairs

- Ultralight backpacking: Perfect — pack to 9 × 5 × 5 in, 16-25 oz, 3-4 breath inflation. - Thru-hiking: Ideal. Many thru-hikers swear by Ether Light XR. - Bikepacking: Compresses small enough for frame bags. - Snow sports / shoulder season: R-Value 4.1 works to "hard frost" conditions. - Spring/summer/fall camping: Ideal conditions for this mat. - Family camping: Larger sizes work for couples / groups. - Frontcountry camping: Same use as backcountry. - NOT for: Hard winter (use R-Value 5+). Hammocks (need under-quilt). Permanent installation.
