What Is the Lightest Roof Top Tent? Materials Compared
"What is the lightest roof top tent?" sounds like a question with a one-line answer. It is actually two questions: which models does a catalogue itself describe as lightweight, and what does a specific model weigh. The first is answered by the catalogue's own listings — in this catalogue, exactly one model carries a lightweight description. The second has an answer only per model, from the supplier's current specification — and any article that prints a league table of model weights without that paper is guessing with your roof load. This guide answers the first question from the listings and tells you how to get the second answered reliably.
What Each Architecture Is Made Of
A soft shell roof top tent is a folding fabric structure: a base frame, a mattress, tent fabric and a travel cover. In this catalogue the SRT14E's listed build shows the full recipe — welded aluminum tube base, aluminum anodized poles and ladder, 420D polyester fabrics, a 60mm mattress and a 680g/1200D PVC travel cover. There is no rigid shell in that stack. A hard shell model adds exactly that: an ABS, aluminum or fiberglass shell large enough to swallow the tent, plus its opening hardware. The shell buys transit protection and the step-up shelf story described in the stocking guide. What either stack weighs, however, is not something this catalogue publishes — no per-model totals, no component weights — so no weight ranking between the two constructions, or between ABS, aluminum and fiberglass versions within hard shell, can be drawn from published paper, and this guide will not pretend otherwise. The comparison has to wait for confirmed packed weights, model by model.
The Listed Lightweight Models
The catalogue does name its lightweight intent in one place: the SRT20-130 is listed as an "OEM Custom Foldable Rooftop Tent, Soft Cover Lightweight" — lightweight is part of the model's own catalogue description, within the SRT20 group at a US$400–500 band. The SRT20-130D (off-road SUV) and SRT20-130V2 sit in the same group, and neither carries a lightweight description, nor does any other model in the soft shell family. If your programme is weight-led — smaller vehicles, lower rack ratings, customers who remove the tent between trips — the SRT20-130 is the listed starting point for your enquiries, and every other model on the shortlist enters the comparison only once its packed weight has been requested in writing, because only the SRT20-130 carries the lightweight description.
Where Tent Weight Actually Matters
Three moments. While driving, tent weight plus rack weight counts against the vehicle's dynamic roof rating — the full explanation is in the weight limits guide. While mounting, weight is a handling question: every roof top tent is a two-person lift, and the lighter model — whichever one the confirmed packed weights say that is — is the one your customers will actually take off between trips instead of leaving mounted all season. And while camping, weight matters least — a parked folding tent shares its sleeping load between the roof and the ladder, as the weight guide explains. Buyers who fixate on the parked number and ignore the driving number have the priority backwards.
How to Compare Weights Honestly
Ask each supplier for the packed weight of the exact model, in writing, in the current specification revision — the same confirmation discipline the buying guide applies to every specification. Compare like with like: packed weight should include the ladder, mounting hardware and travel cover, because that is what rides on the roof; the SRT14E's included list (tent, cover, ladder, two bars, mounting parts) is the checklist to measure a quote against. Then run the vehicle-side arithmetic. A tent that is five kilograms lighter but leaves the combination over the dynamic rating is not the light choice — the light choice is the one that fits the vehicle with margin. For a weight-sensitive programme, that arithmetic can only be run on confirmed figures — which is why the SRT20-130, the one model in its group listed as lightweight, is the natural first model to request a packed weight for, alongside every other model on the shortlist.
The Short Answer
Within this catalogue, the SRT20-130 is the model listed as lightweight — the only lightness claim the published record makes. No construction family can be ranked lightest from that record, because per-model weights are not published. Any specific number for a specific model should come from the supplier's current specification sheet — request it in your enquiry, obtain the full packed weight of each model you are comparing, and treat any unverified weight figure, from any source, as marketing rather than data.
The Components, Listed in Words
Since per-model totals are not published in this catalogue, the only comparison a buyer can make from published paper is an inventory: which components a design carries. An inventory is not a weight — it becomes one only when the supplier confirms the packed total. The soft shell stack, as listed on the SRT14E, is a welded aluminum tube base with an anti-scratch aluminum sheet, aluminum anodized poles and ladder, polyester fabric walls and fly, a foam mattress and a PVC cover. The hard shell stack replaces the PVC cover with a full rigid shell — ABS on the ABS320-130 and ABS600-160, aluminum on the ALU line, fiberglass on the Tallsail and the FRP SFRP-82 — and adds the shell's hinge or strut hardware. That inventory is as far as published evidence honestly goes: the catalogue publishes no component weights and no model totals, so no component or construction can be ranked heaviest or lightest from it, and within hard shell no weight ranking between ABS, aluminum and fiberglass versions can be drawn either, because the figures are not published — request them per model if the ranking drives your decision.
Light for Whom?
Different buyers mean different things by light, and the answer changes with the meaning. For the rack-rating-limited buyer — a smaller car, a modest bar rating — light means total packed weight against the dynamic rating. The SRT20-130 is the one model in this catalogue listed as lightweight, which makes it the natural first model to request a packed weight for — a starting point for the comparison, not a verdict on the weight of any other model or family. For the owner who mounts and removes the tent by hand every trip, light means handling: a folding tent is a two-person lift that two people can actually do monthly without dreading it. For the fleet buyer, light means freight density across a season of containers. Name which buyer you are before asking the question; whichever meaning applies to you, the deciding comparison is the per-model packed weight from the current specification — request it for every model on your shortlist rather than assuming a group or a line carries it — and in the fleet case, pack dimensions may matter as much as kilograms, which is one more figure to confirm per model rather than assume.
A Word on Mattresses and Ladders
Two included components quietly shape a tent's packed weight and neither is optional. The mattress on both SRT reference models is a 60mm foam unit with a washable cover — real comfort weight that owners feel every night and curse only at the lift. The ladder is aluminum on the listed models; a steel ladder on any competing quote should be counted carefully in the total. When you compare two soft shell quotes and one is mysteriously lighter, run down the included list — cover weight class, mattress thickness, ladder material — before believing the total. Lightness achieved by quietly thinning the mattress or omitting the mounting hardware is not lightness your customers will thank you for.
