Olympus Sleeping Bags

Olympus

Olympus 450 | Olympus 450 Women's

A perfect first down bag that's ideal for camping and backpacking trips through the warmest months whilst still giving enough insulation for the cooler nights of late Spring and early Autumn.

 

Built better

For those taking their first forays into the mountains, the Olympus is an excellent down-filled sleeping bag for those on more modest budgets.

 

It offers a well thought-out and compelling feature-set which includes CODEX® audited down and PFC-Free fabrics. Packing down smaller, weighing less and likely to last far longer than nearly any comparable synthetic bag this is an ideal bag for Spring, Summer and early Autumn.

 

Features | Fill

Down is a unique and exceptional insulation. It is more compressible, longer-lasting, and offers better warmth for its weight than any other fibrous insulation, achieving this through a structure that traps maximum still air while weighing as little as possible. Geese, Ducks and Swans all possess down feathers underneath their flight feathers, but as all of Mountain Equipment’s down is a by-product of the meat industry, our down is only sourced from Geese and Ducks. The down is removed from the birds at slaughter and processed to make it clean, hygienic and fluffy.

 

600 Fill Power Duck Down

A high quality duck down. Sourced from China, with an actual minimum down cluster content of 80% and individually tested at the point of filling to ensure a minimum fill power of 600. DOWN CODEX® approved.

 

DOWN CODEX®

In 2009 Mountain Equipment became one of the first outdoor brands to introduce independent auditing of our down supply chain. Quietly introduced, without fanfare or press-releases, DOWN CODEX® set out to understand an industry and supply-chain that was largely ignored and certainly little understood.

 

All products contain a code that can be entered into our DOWN CODEX® website to trace the down that they contain. Not only can you identify the source of your down but the audit relating to that source and the down batch test results can also be viewed.

 

 

Features | Fit

The fit of a sleeping bag is crucial in optimising performance. A well-fitting sleeping bag is not only highly comfortable it also reduces dead air space and maximises thermal efficiency.

Alpine 2.0 Fit

Slightly more tapered in the upper body and in the legs than our Mountain Fit, our Alpine Fit maximises thermal performance while minimising weight.

Features | Fabric

Fabric technology is advancing all the time and we continually seek out those fabrics that offer the lowest weight, maximum breathability, compressibility and comfort.

HELIUM™ 30D outer

Helium fabrics are our range of high performance woven downproof fabrics. Lightweight and ultra-compressible, Helium fabrics are the perfect choice for any product where weight and bulk are a prime concern. Their densely woven structure and use of fine denier yarns ensures these fabrics are down-proof, tear-resistant and highly breathable.

 

Downproof by construction, they do not use membranes and as such have unimpeded breathability. A nanoscale durable water repellence provides water resistance. Helium fabrics are constantly evolving as our fabric partners develop superior technologies. Weaving is a constantly changing field and in recent years the speed of developments has only increased. Before we commit to any new fabric, however, it undergoes extensive laboratory and field testing. Only the best survive.

Supersoft 30D lining fabric

Supersoft™ 30 is our legendary performer chosen for its breathability and durability. Weighing just 49g/m² provides exceptional durability with a soft hand and good breathability.

Features | Baffles

Baffle structure is crucial to the performance of down sleeping bags. Without it, even the best quality down will not loft and insulate to its full potential. Baffles affect a sleeping bag’s durability, weight, and the migration of down inside them – they are the building blocks from which sleeping bags are made.

 

Our neck baffles and entry-zip baffles are vital in reducing the ‘chimney effect’ of hot air flowing out of the sleeping bag’s openings, and are also useful in reducing the ‘bellows effect’ of the movement of a restless sleeper pumping warm air from the bag.

Slanted Box Wall Baffles

A slanted box wall baffle takes the classic box wall and offsets it to reduce thermal bridges and increase thermal efficiency. It also offers improved down migration control. An excellent lightweight construction technique.

Good Night's Sleep Guarantee

Every Mountain Equipment sleeping bag comes with a separate ‘A Good Night’s Sleep Guaranteed’ temperature rating.

Features | Hood and Foot Piece

The head loses a lot of heat and is very sensitive to changes in temperature, making good hood design crucial to the performance of any sleeping bag. A good hood will also keep the neck warm and reduce the ‘chimney effect’ of hot air escaping the body of the sleeping bag.

 

Cold feet can spell the end of a comfortable night’s sleep or even the end of an expedition and we have unrivalled experience in designing innovative sleeping bag foot pieces. By controlling the down in a sleeping bag, the foot is kept warmer, and ensuring the foot piece fits perfectly around the lower body is crucial.

DC5 Hood

A 5 baffle hood that provides high levels of down control, low weight and excellent insulation. Its roominess imparts excellent versatility and, combined with the easy-run dual tether draw cords, superb comfort.

2 baffle anatomically shaped and offset foot-box

A 2 baffle foot piece baffle construction restricts down migration whilst keeping weight and bulk to a minimum.
