  Product Description
The Vango Polaris Kingsize Sleeping Bag offers genuine room to move for couples who find standard double bags too restrictive. It's wider and longer than typical double sleeping bags, giving you proper space to shift position without disturbing your partner or feeling compressed. The ThermoLock Pro Insulation maintains warmth even when damp, which matters during multi-day trips in British weather when condensation builds up inside tents. The offset double layer construction places seams in a way that prevents cold lines running through the bag, whilst the insulated zip baffle stops heat escaping along the full length of the closure. You'll find the Polair SuperSoft shell fabric breathable enough to prevent that clammy feeling you get with cheaper synthetic bags.

This bag uses Grade A insulation fill that keeps its loft better than budget alternatives. The shaped hood with drawcord adjustment lets you seal in warmth around your head on cold nights, or loosen it off when temperatures rise. The auto-lock two-way zip won't accidentally open during the night, and you can unzip from the bottom for ventilation without exposing your upper body to cold air. The square carry bag makes packing easier than trying to stuff it into a compression sack, though it does take up more space in your car. Hanging loops let you air it out properly between trips, which extends the life of any synthetic sleeping bag. The zip guard works well to prevent snagging on the lining.

This bag suits couples who camp regularly in spring through autumn, particularly those over 6 feet tall who've struggled with standard double bags. The EN ISO 23537-1:2022 independent testing gives accurate temperature ratings you can trust when planning trips. The Polair snug lining (190T brushed polyester) feels comfortable against skin and the horizontal stitching keeps insulation evenly distributed, preventing it from bunching up in one area after repeated use. If you're transitioning from separate single bags to sharing, the extra width makes the adjustment easier.

Frequently Asked Questions


What are the actual dimensions of the Vango Polaris Kingsize sleeping bag?
Whilst Vango doesn't publish exact measurements for this model on standard spec sheets, kingsize double sleeping bags typically measure around 200-220cm in length and 150-160cm in width when laid flat. This makes them approximately 20-30cm wider than standard double bags (which are usually 130-140cm wide) and 10-15cm longer. The extra dimensions accommodate taller users and couples who need more space than traditional double bags provide.
What temperature rating does the Polaris Kingsize have?
This bag carries EN ISO 23537-1:2022 independent testing certification, which means the temperature ratings have been verified by a third-party laboratory rather than estimated by the manufacturer. The Polaris range typically suits three-season camping in the UK (spring through autumn), with comfort ratings that work for most campers in temperatures down to around 7-10 degrees Celsius. The ThermoLock Pro insulation provides better performance in damp conditions than standard synthetic fills.
What's the difference between offset double layer construction and single layer construction?
Single layer construction stitches straight through from the outer shell to the inner lining, creating continuous seams where the needle has compressed the insulation. These seams become cold spots because there's minimal insulation at the stitch line. Offset double layer construction uses two separate layers of insulation with staggered seam placement, so the stitching on one layer sits beneath insulated fabric from the other layer. This prevents continuous cold lines running through the bag and improves overall heat retention without adding significant weight.
Will the Polaris Kingsize fit inside a standard tent bedroom?
Most family tents marketed as having a double bedroom measure 210-220cm wide internally, which accommodates kingsize sleeping bags with minimal space either side. Smaller two-person backpacking tents with 130-140cm wide sleeping areas won't fit this bag. Check your tent's internal width measurement before purchasing. The bag works well in bell tents, family tunnel tents, and larger dome tents where bedroom compartments exceed 200cm in width. In tight spaces, the square shape means less wasted room at corners compared to mummy-style bags.
How does ThermoLock Pro insulation perform compared to standard hollow fibre fills?
ThermoLock Pro uses a multi-hole fibre structure that traps more air pockets than standard hollow fibre insulation, improving warmth-to-weight ratio. The key advantage shows up in damp conditions where standard synthetic fills compress and lose loft. ThermoLock Pro maintains its structure better when exposed to tent condensation or moisture from breath and body heat. The insulation also returns to full loft faster after compression in the carry bag, whilst standard fills can take longer to expand properly. This matters on multi-day trips where you're packing and unpacking repeatedly.
Can you zip two Polaris Kingsize bags together?
The Polaris Kingsize is already a double bag designed for two people, so zipping two together would create an extremely large sleeping area that most tents couldn't accommodate. Vango sleeping bags typically require matching left and right zip configurations to couple together. The kingsize format doesn't usually come in left/right zip variants because it's already designed as a shared bag. If you need more width than the kingsize provides, you're better off using two separate single bags laid side by side rather than attempting to couple kingsize bags.
What's the packed size and weight of the Vango Polaris Kingsize?
Vango hasn't published official weight specifications for this model, but kingsize double sleeping bags with synthetic insulation typically weigh between 3.5-4.5kg and pack down to approximately 40-45cm length by 30-35cm diameter in the square carry bag. This makes them suitable for car camping, campervan use, and caravan pitches where weight and pack size aren't critical factors. The square-shaped carry bag takes up more boot space than compression stuff sacks but makes packing easier and puts less stress on the insulation fibres during storage.
