  Product Description
The Vango Gravity Grande delivers proper warmth and comfort for camping trips where you need reliable sleep without spending a fortune. This square-shaped sleeping bag uses Grade A Thermolock insulation that keeps working even when damp, paired with Polair fabric on both the shell and lining. The 190T brushed polyester microfibre lining feels soft against your skin, while the outer shell stands up to repeated use and machine washing. The square cut gives you more room to shift position during the night compared to mummy-style bags, which matters if you're not a still sleeper.

Vango's single-layer stitch construction spreads the insulation evenly throughout the bag, reducing those annoying cold spots you get with cheaper sleeping bags. The integrated headrest and shaped hood with drawcord help retain heat around your head and neck, where you lose warmth fastest. You can adjust ventilation with the two-way zip, opening from top or bottom depending on conditions. When morning comes, hanging loops make it straightforward to air out the bag before packing away. The included stuffsack with drawcord keeps things compact in your car boot or rucksack.

This sleeping bag meets ISO 23537-1:2022 certification, meaning it's been independently tested for temperature ratings rather than relying on manufacturer claims alone. The Polair shell and lining both use 190T polyester that goes in the washing machine, useful after muddy festivals or extended camping trips. While the square shape does take up a little more room than similarly warm mummy bags, it rewards you with extra freedom to move and a more spacious, relaxed sleep feel. The woven zip puller makes operation easier in the dark, and the Insulation Lock S-stitching keeps the synthetic fill where it belongs rather than bunching up after repeated compression.

Frequently Asked Questions


What temperature rating does the Vango Gravity Grande have?
The Gravity Grande is ISO 23537-1:2022 certified, meaning it's been independently tested for temperature ratings. Vango uses this international standard to provide accurate comfort and limit temperatures, though the specific ratings vary by model within the Gravity range. The ISO certification means the temperatures quoted are based on standardised laboratory testing rather than estimates.
Can you machine wash the Vango Gravity Grande sleeping bag?
Yes, both the Polair shell and lining are machine washable. Use a large capacity washing machine on a gentle cycle with mild detergent. The synthetic Thermolock insulation handles washing better than down fill and dries faster. Hang the bag using the integrated hanging loops after washing to ensure even drying, and store it loosely rather than compressed to maintain the insulation's loft between trips.
What's the difference between square and mummy shaped sleeping bags?
Square shaped sleeping bags like the Gravity Grande offer more internal space and freedom to move around during sleep, making them comfortable for people who shift position at night or feel restricted in tighter bags. Mummy bags taper towards the feet and fit closer to your body, which makes them warmer for the same insulation weight and pack smaller. Square bags work well for car camping, festivals, and situations where pack size isn't critical.
What does Thermolock insulation mean on Vango sleeping bags?
Thermolock is Vango's synthetic insulation technology that maintains its insulating properties when damp or wet, unlike down which clumps and loses warmth. The high loft synthetic fibres trap warm air close to your body and continue working in humid conditions common during UK camping. Grade A Thermolock represents the higher quality specification within Vango's insulation range, offering better warmth-to-weight ratio and durability through repeated compression cycles.
How do you properly store a synthetic sleeping bag?
Store the Gravity Grande loosely in a large breathable storage sack or hung up, rather than keeping it compressed in the stuffsack between trips. Continuous compression damages the synthetic insulation's ability to loft and trap warm air. The stuffsack is for transport only. Keep the bag in a dry place away from direct sunlight and moisture. Before storing, make sure it's completely dry using the hanging loops to air it out after camping trips.
What does single-layer stitch construction mean?
Single-layer stitch construction means the sleeping bag has one continuous layer of insulation held in place by stitching that goes through from the outer shell to the inner lining. The Gravity Grande uses S-stitching (Insulation Lock) to distribute the fill evenly and reduce cold spots where stitching compresses the insulation. This construction method is lighter and less bulky than double-layer systems, making it suitable for bags where weight and pack size matter but extreme cold performance isn't required.
Can you zip two Vango Gravity Grande bags together?
Vango sleeping bags with compatible zips can often be paired together to create a double bag, but you need matching left and right zip configurations. The two-way zip on the Gravity Grande allows you to unzip from top or bottom for ventilation control. Check the specific zip configuration when buying if you want to pair bags together, as you'll need one left-hand and one right-hand zip model from the same range for proper compatibility.
What's the packed size of the Vango Gravity Grande?
The Gravity Grande comes with a drawcord stuffsack designed to compress the bag for transport. Square shaped sleeping bags with synthetic insulation generally pack larger than equivalent mummy bags because of the extra fabric and insulation volume needed to cover the wider shape. For car camping, festivals, or campervan trips where space isn't as tight as backpacking, the trade-off between pack size and sleeping comfort usually favours the square design.
