  Product Description
The Vango Sierra Air TC 300 is a three-person polycotton tent that combines traditional canvas comfort with modern inflatable technology. Built around AirBeam frames rather than conventional poles, it pitches in minutes using the included pump and features a stand-up height living area with a pre-attached front extension. The Sentinel TC fabric (a cotton-polyester blend) offers natural breathability and temperature regulation that synthetic tents can't match, staying cooler in summer heat and providing better insulation when temperatures drop. You'll find two Lights-Out bedrooms with darkened fabric that blocks early morning sun, plus a fully sewn-in groundsheet that keeps draughts and insects outside where they belong.

Practical touches make this tent work for families and couples who need proper living space at camp. The drop-down door step design allows wheelchair and pram access without the usual tent threshold obstacles. SkyTrack II rails run along the ceiling for hanging lights and storage exactly where you need them, whilst the toggled inner divider lets you configure the sleeping area as two separate bedrooms or one larger space. Diamond clear windows and large mesh roll-away doors flood the interior with natural light and airflow. The TBS II tension band system (something Vango has patented) braces the beams at three points to handle strong winds better than unsupported inflatable structures.

Crafted from durable polycotton fabric for superior breathability and long-lasting performance, this Vango tent is perfect for relaxed weekend camping or longer stays where you have space to enjoy its generous footprint and excellent stability from the additional guylines. Weighing around 21.4kg when packed, it’s designed for comfort and durability rather than lightweight backpacking, while the fabric’s natural performance means it should be fully dried before storage to maintain its quality. The Easy Pack carry bag simplifies packing, protecting the fabric from strain and making setup and pack-down easier. High-vis orange guylines enhance visibility and safety, AirSpeed valves allow quick inflation and deflation, and multiple AirZone ventilation points keep the interior fresh and comfortable for a better all-round camping experience.

Frequently Asked Questions


What does TC fabric mean and how does it differ from standard polyester tents?
TC stands for Technical Cotton, which is Vango's term for polycotton fabric that blends cotton and polyester fibres. The Sentinel TC material used in the Sierra Air 300 breathes naturally like canvas, reducing condensation and regulating internal temperature better than fully synthetic tents. In hot weather, air passes through the weave to keep the interior cooler. In cold conditions, the thicker fabric provides more insulation than standard polyester. The trade-off is extra weight compared to synthetic tents and the need to dry the tent thoroughly before packing to prevent mould growth.
How long does it take to pitch the Sierra Air TC 300 and what pump pressure is needed?
The Sierra Air TC 300 typically pitches in 10-15 minutes once you've done it a couple of times. The included double-action pump features a built-in pressure gauge, and Vango AirBeams inflate to 7 PSI. You peg out the groundsheet first, connect the pump to each AirSpeed valve in turn, inflate the beams, then tension the TBS II bands and guylines. The AirBeam structure is ready when the beams feel firm to squeeze and the pressure gauge reads 7 PSI. One person can manage this alone, though two people make positioning the tent easier before pegging.
Will three adults fit comfortably in the Sierra Air TC 300 bedrooms?
The bedroom space works better for two adults plus a child or two adults with extra gear room. Vango rates the bedrooms at 70cm width per person, which means three standard camping mats will technically fit side-by-side, but you'll be sleeping quite close together. Most users run this tent as a couple's tent with one bedroom for sleeping and the second for storage, or as a family tent with parents in one bedroom and a child in the other. The toggled divider can be removed to create one large sleeping area if you prefer a single king-size bedroom configuration.
What's the standing height in the living area and how much space does the pre-attached extension add?
The main living area offers full stand-up headroom for most adults, with the pre-angled beam design creating more usable internal space than a simple curved profile. The pre-attached front extension adds significant covered outdoor space without requiring a separate canopy purchase. This extended area works well for cooking, muddy boots, or sitting outside under cover when rain arrives. The drop-down door steps at both the main entrance and extension make access easier than traditional tent thresholds, particularly useful if you're moving camping furniture in and out or need wheelchair access.
How effective are the Lights-Out bedrooms at blocking morning light?
The Lights-Out bedroom fabric uses darkened material that blocks most early morning sunlight, letting you sleep past dawn without the tent interior lighting up like a lantern. You'll still get some light seepage around zips and at ground level where the inner meets the flysheet, but the bedroom stays significantly darker than standard tent inners. This feature works particularly well during summer camping when sunrise can be as early as 4:30am in the UK. The fabric doesn't create complete blackout conditions like bedroom curtains at home, but it makes a noticeable difference to sleep quality compared to traditional tent inners.
Can the Sierra Air TC 300 handle bad weather and strong winds?
The Sierra Air TC 300 includes Vango's TBS II tension band system, which braces each AirBeam at three points to reduce sideways flex in strong winds. When pitched properly with all guylines tensioned and pegs secure, the tent handles typical UK camping weather including rain and moderate winds. The polycotton fabric is more resistant to UV damage than polyester and the sewn-in groundsheet prevents draughts from underneath. That said, this is a family camping tent designed for seasonal use, not a four-season expedition shelter. In exposed locations or during weather warnings, all family tents become vulnerable. The high-vis guylines help prevent trip hazards in low light, and the multiple ventilation points (AirZone system) reduce condensation buildup during wet weather.
What maintenance does polycotton tent fabric require compared to synthetic tents?
Polycotton tents need proper drying before storage to prevent mould and mildew, which means you can't pack them away damp like many synthetic tents. After a wet camping trip, pitch the Sierra Air TC 300 in your garden or garage to dry completely before folding. The Sentinel TC fabric should be brushed clean rather than pressure washed, and avoid using harsh detergents that strip the water-repellent treatment. Over time, polycotton may need reproofing with a suitable tent treatment to maintain water resistance. The fabric lasts longer than standard polyester under UV exposure and handles temperature extremes better, but requires more careful storage. Never store a damp polycotton tent or you'll find black mould spots when you open it next season.
What accessories work with the SkyTrack II system and are they included?
The SkyTrack II rail system runs along the tent ceiling and accepts Vango's compatible hanging accessories including light hangers, storage organisers, and towel hooks. These accessories feature a slider mechanism that clips into the track and moves along freely, letting you position items exactly where needed. The tent includes basic lantern hanging points but SkyTrack accessories are sold separately. This system beats traditional tent loops because you can slide organisers to one side when not needed and adjust positioning without re-tying anything. The flexibility works well for families who need different configurations - cooking gear within reach during meal prep, then cleared away for living space afterwards.
