Why Criterion?
For two decades, Criterion Down Sleeping Bags has been a symbol of quality in the outdoor industry. Founded in 2003, we’ve built our reputation on a commitment to build quality. We use only branded Pertex fabrics and ethically sourced Polish goose down in our sleeping bags.
Minimalist Ultralight Design
Our sleeping bags are designed for enthusiasts who want to move quickly and as lightly as possible in the great outdoors. Designed in the UK, our goose down sleeping bags are perfect for adventurers who want to go as fast and light as possible without sacrificing warmth or comfort.
Manufacturing Quality
Criterion is a UK company. Our sleeping bags are made in the EU, where machinists are protected by employment law. We only used branded fabric and ethical down (RDS and Downpass Certificated)
Armed Forces Discount
We are happy to offer any member past or present of our armed forces a discount on the purchase of our sleeping bags. This covers full time personnel, reservists, cadets and members of auxiliary organisations such as the Royal Fleet Auxiliary.
Please email sales@criterion-sleepingbags.co.uk for a discount. This is because more will be offered to those needing bags for active deployment.
Real talk from our real customers
Loyal customers, they don’t just come back, they don’t simply recommend you, they insist that their friends do business with you.
I just can’t recommend Shoptimizer enough. I feel like I’m on a first-name basis with some of the crew, they’re just so unbelievably helpful, no matter what the question. Their products are also so beautifully well made and easy to maintain, they’ll last for years to come.


Every order from Shoptimizer has been an amazing experience. their site provides lots of detail so I know exactly what I’m getting and their customer support is just outstanding. I needed to swap an item for a different size and they arranged everything for me within 24 hours.
