Product Description

Strata Duo LT is an all-season insulated inflatable pad engineered for reliable warmth and comfort. Lab-tested to an R-Value up to 7.5 under ASTM F3340-22, it blocks cold ground so you actually rest. A Duo Air Chamber design adds fail-safe security: even if one chamber goes down, you still retain meaningful insulation performance (R > 5) far beyond closed-cell foam pad. At 8 cm thick, it spreads body pressure for a calm, drift-off-fast feel, and the 20D nylon shell keeps weight low for backpacking. Prefer quick, clean inflation over breath moisture? The included electronic air pump gets you there fast. Wondering what is the best camping sleeping pad for year-round trips or a lightweight backpacking sleeping pad that stays warm in winter? This is the one. Grab yours and sleep like it is summer.

What’s Included?

• Strata Duo LT Sleeping Pad

  • This complimentary first-generation pump is supplied as a prototype, and performance may vary.
  • When connected to a power bank or USB source, it may need a gentle knock to begin running.

Warnings

• Pump pressure limit: When using non-Asgard pumps, do not exceed 0.7 PSI to avoid delamination.
• Surface check: Clear sharp objects before setup to reduce puncture risk.
• Moisture control: Prefer electronic pump inflation to minimize internal moisture and extend life.
• Important: The included electronic air pump is a first-generation test unit. It may not function like a retail-grade pump. When using with a power bank, it may need a gentle knock to activate.

How to Use?

1. Unroll and stage:
   • Lay the pad flat with valves accessible; clear the ground of sharp debris.
2. Inflate Chamber A:
   • Attach the included electronic pump, or use the Asgard Packraft Hand Pump for manual control.
   • Inflate until the pad takes shape but remains slightly soft.
3. Inflate Chamber B:
   • Repeat for the second chamber; fine-tune firmness by brief pumps or by tapping the release.
   • If using another brand of pump, do not exceed 0.7 PSI.
4. Adjust for comfort:
   • Aim for a slight give under hips and shoulders to avoid pressure points.
5. Deflate and pack:
   • Open valves, roll tightly to purge air, and stow to packed size.

FAQs

Q: What is the best camping sleeping pad for year-round trips?
A: Strata Duo LT delivers up to R 7.5 warmth, dual-chamber safety, and 8 cm comfort for true four-season use.

Q: The pad says R-Value 7 but you mention 7.5. Which is correct?
A: The product is printed with R-Value 7 for consistency, but our official ASTM F3340-22 test results show it reaches up to 7.5. We print a conservative figure to ensure realistic expectations in all conditions.

Q: Is a self inflating sleeping pad warmer than an inflatable with a pump?
A: Not necessarily. This inflatable pad is lab-tested under ASTM F3340-22 to an R up to 7.5, exceeding many self inflating designs.

Q: How does it compare to closed-cell foam pads?
A: Closed-cell foam pads are lighter and inexpensive but much less warm and far bulkier to pack. Strata Duo LT delivers far higher insulation (tested up to R 7.5) and retains meaningful warmth even if one chamber fails (R > 5), while packing much smaller than most closed-cell pads.

Q: Why does the included electronic air pump sometimes not start immediately?
A: The included electronic air pump is a complimentary first-generation prototype provided as a gift. Because it’s an early test unit, performance can vary. When powered from a bank or USB source, it may need a gentle knock to activate. You can also use any other compatible pump under 0.7 PSI if you prefer consistent operation. You can also use a manual option like the Asgard Packraft Hand Pump.

Q: Can I use other electronic pumps?
A: Yes, but keep pressure under 0.7 PSI to avoid internal delamination.

Q: What are the packed sizes and weights for backpacking?
A: Regular packs to 3.54 x 3.54 x 7.48 in at 20.1 oz; XL to 3.54 x 3.54 x 7.87 in at 23.3 oz.

Q: Is it suitable for winter camping in the US (Sierra, Rockies, Northeast)?
A: Yes. The tested R value up to 7.5 is designed for freezing ground and alpine nights.

Q: Will it handle Canadian cold snaps (BC, Alberta, Quebec)?
A: Yes. The four-season rating and dual chambers help maintain warmth in Canadian winters.

Q: Does it include a pump?
A: Yes. An electronic air pump is included for fast, low-moisture inflation.

Q: Where do I get support or start a return?
A: Reach us via the Contact Page or see our Refund Policy.
