Choosing a sleeping bag for UK camping
Cornwall campsite holidays and coastal camping
For a camping holiday in Cornwall, use the overnight forecast for your actual campsite rather than assuming a coastal or summer location guarantees a warm night. Check your sleeping mat, personal sleeping preferences and the bag's confirmed comfort guidance together.
Dartmoor, the Lake District and Scottish camping trips
For walking trips and upland campsites, check conditions for your route or campsite, including elevation and exposure. A season label alone does not establish suitability. Confirm comfort guidance before planning colder nights.
DofE and Scout expeditions
The Alpha 250 listing describes it as DofE Recommended Kit, and the Alpha 350 description refers to DofE and Scouts recommendations. Confirm your group's current kit requirements, expected conditions, fit and total pack weight before ordering. A recommendation does not guarantee suitability for every expedition.
Choose your sleeping bag and mat together
Your sleeping bag is one part of your sleeping setup. Check your mat's insulation and suitability for the ground conditions. Compare the complete system rather than selecting a bag from its extreme rating.
Frequently asked questions
What is the difference between the Vango Nitestar Alpha 250 and 350?

Which Nitestar Alpha is lighter?
The Alpha 250 is 350g lighter than the 2.0kg Alpha 350. The checked Alpha 450 description does not state its weight, so this guide cannot rank all three by weight.
Is the Nitestar Alpha 450 warmer than the 350?
The checked Alpha 450 description does not provide temperature ratings. Confirm its comfort rating before making a reliable warmth comparison with the Alpha 350.
Is the Nitestar Alpha 250 suitable for UK summer camping?
It may be an option when its listed 2°C comfort guidance suits the expected overnight conditions and your personal needs. Check the campsite forecast and your sleeping mat rather than relying on the season alone.
Which Nitestar Alpha should I choose for autumn camping?
Choose using overnight conditions and confirmed comfort guidance. The 350's 3–4 season label is useful context, but does not guarantee comfort on every autumn trip. Confirm the 450's missing temperature details before selecting it.
Can I use a Nitestar Alpha for DofE?
The Alpha 250 listing describes it as DofE Recommended Kit, and the Alpha 350 description also refers to expedition recommendations. Check your group's current requirements and match the bag to planned conditions and total pack weight.
How tall can I be to use the Alpha 350?
The Alpha 350 listing gives a maximum user height of 190cm and an internal length of 205cm. Its internal chest width is 83cm and foot width is 48cm. Check room and fit rather than assuming all three models have identical dimensions.
Does the Alpha 350 include a compression sack?
Yes. The Alpha 350 listing includes a four-strap compression stuffsack to help reduce packed bulk for transport.
Can I camp at a sleeping bag's extreme temperature?
Do not treat an extreme rating as a normal camping or comfort target. Use confirmed comfort guidance alongside your mat, personal needs and expected conditions.
Where can I compare Nitestar Alpha sleeping bags in the UK?
Use the World of Camping product links in this guide to compare specifications and current purchasing options. Confirm availability and any missing details on the exact product before ordering.
Our recommendation
Start with the Nitestar Alpha 250 if its listed 2°C comfort guidance suits your trip and lower carried weight matters. Compare the Nitestar Alpha 350 if you are considering a 3–4 season bag, checking comfort guidance and fit before committing. For the Nitestar Alpha 450, confirm weight and temperature figures first. Choose for your conditions and complete sleeping setup, not simply the highest model number.
