Looking for a Vango hiking mat for UK walking and camping trips? The Vango Aotrom Thermo uses air-filled channels with reflective and hollow-fibre insulating materials. The Vango Trek Pro 3 Long is a self-inflating foam-core mat designed in a longer format. Start with the construction you prefer, then compare confirmed dimensions, carrying weight, packed size and insulation guidance.
Both mats are on display in the World of Camping showroom at 4 Bamber House, Victoria, St Austell, PL26 8LQ, Cornwall. Visit to view the designs in person and discuss your hiking setup with our team. Check opening hours and current display availability before travelling.

- Shortlist the Aotrom Thermo if you want to investigate an air-filled channel design with ThermoFlex reflective fabric and hollow-fibre insulation. Listed at £89.99.
- Shortlist the Trek Pro 3 Long if you prefer self-inflating foam-core construction and want to check a longer sleeping surface. Listed at £36.99.
- Do not choose on price or model name alone. Neither is established here as lighter, warmer or smaller when packed than the other.

Vango Aotrom Thermo: air-filled channels and insulation
The Aotrom Thermo sleeping mat combines ThermoFlex fabric with ARC, or Advanced Reflective Coating, and a siliconised hollow-fibre core. These materials are intended to help retain heat and insulate the sleeper from the ground.
Its welded air-filled channels mould to the contours of the body and the surface beneath. The listing describes a lightweight construction and small packed size, making it an option to investigate when carrying and rucksack space matter.
Before buying: confirm exact weight, inflated length and width, packed dimensions, inflation method and the exact model's tested R-value. Those numerical specifications are not established by the listing information used here. Do not assume an inflation bag or pump is included.
The word “Thermo” is not a guaranteed minimum sleeping temperature. Choose it around confirmed conditions and the rest of your sleeping system.
Vango Trek Pro 3 Long: self-inflating foam-core construction
The Trek Pro 3 Long is listed as a self-inflating mat made with recycled TrekEco fabric. Its Core Cutting Design reduces material in the foam core with the aim of reducing weight and packed bulk while maintaining comfort and insulation.
EasyGrip embossing is intended to help reduce sleeping-bag movement on the surface. A Fast-Flow valve controls inflation and deflation. Follow the supplied setup instructions, allow time for the foam to expand and do not assume a fixed inflation time or a built-in electric pump.
The Long listing states an R-value of 4.0. The test method is not established in the information used for this guide, so treat that as the listed model figure rather than proof of a like-for-like tested comparison with the Aotrom Thermo.
Before buying: confirm actual usable length and width, packed dimensions, weight and insulation test basis. Do not transfer measurements from a Trek Pro Short or Standard listing to the Long version. “Long” is a model designation, not a fit guarantee.
Which mat is warmer, lighter or smaller when packed?
The information here does not establish a fair numerical ranking. The Trek Pro 3 Long listing states R4.0, while a verified numerical R-value for the Aotrom Thermo is not established here. That does not mean the Aotrom has no insulation; it means we cannot rank the two by comparable verified figures.
Likewise, descriptions such as lightweight and compact are not a substitute for the exact weight and packed dimensions. Check those specifications for the model you will buy, including any inflation accessories you need to carry.

Five checks before buying a hiking sleeping mat
- Fit: compare the exact usable length and width with your height, sleeping position and tent-bedroom floorplan.
- Carrying: check confirmed weight and packed size against your rucksack and total kit load.
- Insulation: check the exact model's tested information and manufacturer guidance against expected overnight conditions.
- Setup: understand inflation, valve operation, included accessories and repair requirements before your trip.
- The whole sleep system: pair the mat with suitable bedding and keep sleeping equipment dry.
Side sleepers should consider support under hips and shoulders as well as width. A tent's person rating does not establish room for a particular mat. Protect either mat from sharp ground and follow its cleaning, drying and storage instructions.

The Aotrom Thermo and Trek Pro 3 Long are both on display in our showroom at 4 Bamber House, Victoria, St Austell, PL26 8LQ. Viewing them side by side can help you understand their different surface designs and discuss which specifications matter for your trips.
Bring your tent's usable bedroom measurements, your sleeping-height requirements and an idea of how much packed space you can spare. Ask our team about any missing specification before deciding. Confirm opening hours and current display availability before setting out, especially if travelling specifically to compare these models.
Whether your plans involve walking trips in Cornwall or campsites elsewhere in the UK, choose for the route and overnight conditions, not simply the season printed on a label. For broader preparation, read our guide to staying warm camping in the UK.
Vango hiking mat frequently asked questions
What is the main difference between Aotrom Thermo and Trek Pro 3 Long?
The Aotrom Thermo has air-filled welded channels with reflective and hollow-fibre insulating materials. The Trek Pro 3 Long is a self-inflating foam-core mat with TrekEco fabric and a Fast-Flow valve.
Which Vango hiking mat should I buy?
Shortlist by your preferred construction, then compare confirmed fit, weight, packed dimensions and insulation guidance for your trip. This guide does not establish one universal best choice.
Which of the two mats is lighter?
A verified numerical weight comparison is not established here. Check the exact models' specifications rather than inferring carrying weight from their names or prices.
Which packs smaller?
The available information does not establish a like-for-like packed-size comparison. Confirm dimensions including the required carry bag and any inflation accessories before choosing for a small rucksack.
Is the Aotrom Thermo self-inflating?
The information here describes air-filled channels, not a confirmed self-inflating foam setup. Check its inflation instructions and required accessories before buying. Do not assume it works like the Trek Pro.
Does the Trek Pro 3 Long have a built-in electric pump?
No built-in powered pump is established in the information used here. Follow its foam-expansion and valve instructions rather than expecting powered inflation.
What R-value does the Trek Pro 3 Long have?
Its listing states 4.0. Confirm the testing basis and manufacturer guidance before comparing it with another mat or choosing for cold conditions.
What is the Aotrom Thermo's R-value?
A verified numerical value is not established in the information used here. Ask for the exact model's tested specification rather than inferring it from the name or insulating materials.
Are these suitable for winter hiking?
No blanket winter recommendation is made. Assess your complete sleeping system against the expected conditions and the exact manufacturer's guidance. Mat thickness or reflective materials alone do not establish winter suitability.
Will the Trek Pro Long fit every taller camper?
Check the actual usable dimensions against the person's height and sleeping style. Its name alone does not guarantee fit, comfort or enough tent-floor space.
Are the Trek Pro Standard and Short available too?
The Standard was unavailable to buy at our 4 November 2026 check, and the Short was not published for online sale. Check current availability rather than assuming every size is offered.
Can I see both hiking mats in your showroom?
Yes. The Vango Aotrom Thermo and Trek Pro 3 Long are on display at World of Camping, 4 Bamber House, Victoria, St Austell, PL26 8LQ, Cornwall. Check opening hours and current display availability before travelling.
Does a showroom display mean I can take one home the same day?
Not necessarily. Display and purchase stock are separate. Contact our team to confirm current stock and collection arrangements before travelling to buy.
Our recommendation
Compare construction in person where possible, then buy on confirmed specifications. The Trek Pro 3 Long is worth investigating for someone who prefers a longer self-inflating format; the Aotrom Thermo is worth investigating for someone interested in an air-channel trekking mat.
