What the Numbers Say

- ▸Price: Big Agnes Rapide SL is cheaper at MSRP by $30 ($170 vs $200). Real-world street prices vary, but the starting MSRP gap is consistent.
- ▸Ultralight classification: the NEMO Tensor All-Season is classified ultralight, the Big Agnes Rapide SL is not. That usually means the heavier product trades grams for durability or features.
- ▸Review coverage: neither has a full review yet. Specifications are taken from current manufacturer product pages.
Detailed Breakdown
Carry weight and packed size
On the published spec sheet, the NEMO Tensor All-Season comes in at 400 grams against the 510 grams of the Big Agnes Rapide SL. That 110-gram gap may sound trivial in isolation but compounds across multi-day trips — at 25 km a day for a week, you're carrying that delta for about 175 km of trail. The NEMO Tensor All-Season's ultralight classification reflects the deliberate design choices that produce the saving: thinner fabrics, simpler architectures, or fewer secondary features.
Price and total cost of ownership
MSRP gap: $30 (Big Agnes Rapide SL cheaper). For most buyers that's the only price number that matters short-term. Long-term cost depends on durability and warranty handling: a product that lasts seven seasons at $200 costs less per use than a product that lasts three at $170. Without long-term field data on both we won't claim a winner on durability, but it's the lens to apply if you re-sell or replace gear infrequently. Look for current sales on either before assuming MSRP is what you'll pay.
Materials and durability
Material composition for both products comes from the manufacturer product pages and is not always reported in directly comparable units. The NEMO Tensor All-Season carries the manufacturer's published spec only; the Big Agnes Rapide SL carries the manufacturer's published spec only. Without a full review of either, treat material and durability claims as starting points rather than verdicts. Reader reviews on REI or Amazon (filtered to verified purchases) often reveal failure modes that brand copy doesn't.
Features and ergonomics
Manufacturer feature descriptions: the NEMO Tensor All-Season — R-5.4 insulated air pad, ~0.40 kg (min, regular), 8 cm thick, dual Thermal Mirror film.. The Big Agnes Rapide SL — Inflatable pad, R-4.8, ~0.51 kg regular, 9 cm thick — value-oriented (2024 redesign). Pay particular attention to fit, adjustability, and hand-feel — three dimensions that don't show on a spec sheet and that disproportionately determine whether you'll actually reach for the gear after the first trip.
Use-case fit
The insulated air pads category covers a wide range of trip styles. For weight-counted thru-hikes, lean toward the NEMO Tensor All-Season — every gram in your pack rides with you for thousands of kilometers. For weekend trips and base-camp days, weight matters less and durability, comfort, and feature count matter more — the heavier of the two on this page often makes more sense in those scenarios. For three-season generalist use, our recommendation: prioritize the product you can handle in a store or borrow from a friend, because neither has a full review on this site yet.
Brand support and availability
NEMO and Big Agnes both produce insulated air pads for the North American and EU markets. Availability varies: smaller cottage brands may require direct-from-manufacturer ordering with 2-6 week lead times, while bigger brands stock through REI, Backcountry, and large EU outdoor chains with same-week shipping. Before buying either, check the manufacturer's warranty terms (often 1, 2, or 10 years depending on brand culture) and the brand's reputation for honoring claims on minor failures versus catastrophic ones. Neither product has a full review on this site yet, so check owner reports for warranty experiences before buying.
Frequently Asked Questions
Which is lighter, the NEMO Tensor All-Season or the Big Agnes Rapide SL?
On published manufacturer specs, the NEMO Tensor All-Season is the lighter of the two by 110 grams (0.40 kg vs 0.51 kg). For ultralight backpackers counting grams in the insulated air pads category, that's a meaningful difference.
Which costs less, the NEMO Tensor All-Season or the Big Agnes Rapide SL?
At MSRP, the Big Agnes Rapide SL costs $30 less than the NEMO Tensor All-Season ($170 vs $200). Real-world prices fluctuate with sales and seasonal promotions, but the spec-sheet starting price is clear.
Does this site have full reviews of both products?
Not yet. Neither the NEMO Tensor All-Season nor the Big Agnes Rapide SL has a full review on this site yet. This comparison is built from published manufacturer specifications only, clearly labeled. Treat it as a shortlist starting point rather than a verdict.
Is the NEMO Tensor All-Season ultralight by industry standards?
Yes. The NEMO Tensor All-Season is classified ultralight in our database (0.40 kg, sub-threshold for its sleep system category). Ultralight insulated air pads typically means built for thru-hikers and gram counters rather than three-season car-camping use.
Is the Big Agnes Rapide SL ultralight by industry standards?
No. The Big Agnes Rapide SL at 0.51 kg sits above the ultralight threshold. That usually buys more durability or features at the cost of weight — appropriate for car-camping, base-camp, or shoulder-season trips.
Is the price difference worth it?
The NEMO Tensor All-Season costs $30 more than the Big Agnes Rapide SL but is 110 g lighter. That's roughly $0.27 per gram saved. Whether that's worth it depends on how often you carry it: a thru-hiker saving grams every day for months will rationalize the premium more easily than a weekend backpacker.
Where can I read the full review?
Neither product has a full review yet. The current page lists manufacturer-published specifications for both. We'll add full research-based reviews as published testing and owner feedback accumulate.
Bottom Line
Winner on weight: the NEMO Tensor All-Season by 110 g (0.40 kg vs 0.51 kg). If your trip style punishes grams, that's the pick.
Winner on price: the Big Agnes Rapide SL at $170 versus $200 for the NEMO Tensor All-Season — a $30 gap that may close or widen with current sales.
