The Sac is an excellent, all-purpose sleeping bag made using the latest in synthetic fill technology. The Thermolink fill is exceptionally strong, warm and lightweight, encased in a highly breathable, water-repellent and durable 20 D Vapour Vent V2 shell. The roomy, tapered rectangular bags are easy to care for and stay warm when wet, with options available in three temperature ratings (ISO 23537.1 limit of comfort -1, -5 and -8°C) in regular and large sizes. The full-length YKK #5 zip has an anti-snag slider and opens at both ends for easy venting.
FEATURES
Tapered rectangular shape offers versatility and roomy comfort
Thermolink insulation uses hollow-core fibres and thermal bonding for excellent warmth-to-weight and durability
The half-moon foot-box is wide and cosy, while base draft tubes keep you warm and toasty
The contoured hood encloses your head, cinching tight while leaving enough space for your nose and mouth
The elasticised 3D neck baffle effectively traps warmth around the neck and shoulders
Full-length side zip from shoulder to ankle, with independent zip along the bottom of bag. Both are YKK #5 zips with locking sliders and innovative, anti-snag covers
Independent zip on the foot (from ankle to ankle) can be opened fully for extra ventilation
The two zips meet above the ankle, with a 10 cm crossover to keep draughts out
Selecting azip side is easy: when lying in a sleeping bag, a left-hand zip (LH) is on your left side
Joined at the zip: full-length zips allow models with compatible left and right zips to be zipped together

FEMALE AND MALE RATINGS ISO 23537-1: INDEPENDENTLY TESTED TEMPERATURE RATINGS
All ONE PLANET sleeping bags are temperature rated in accordance with ISO 23537-1. This is the only globally recognised standard for the temperature testing of sleeping bags, and gives ratings for both females and males. Sleeping bags tested to the International Organisation for Standardisation 23537-1 (Requirements for sleeping bags) allow users to make informed, educated and accurate decisions.
The ISO 23537-1 testing methods allows objective comparisons of the warmth of different shapes (mummy, tapered rectangular and rectangular), sizes (small, regular and large) and how this translates into warmth for both females and males. When reading the temperature rating information, the ’Comfort’ rating gives an accurate figure for the lower limit of comfort for a standard female, while the ‘Limit’ is an accurate gauge of the lowest limit of comfort for a standard male.
Not all manufacturers test to this standard, nor give information about how they arrive at their temperature ratings. As a result, care should be taken when comparing claims of warmth.
THERMOLINK
Thermolink synthetic fill is light and warm, incredibly durable, and naturally hypoallergenic. It is made up of multiple thermally-bonded layers, making it strong, giving it class-leading warmth-to-weight, and eliminating the need for sewn-through stitching (and the accompanying heat loss). The inner layer is made up of fine, soft fibres that contour to the body. The middle layer uses larger hollow fibre for loft and insulation, with a thermal barrier made up of high-density fibre on the outside
WARM WHEN WET
The insulative qualities of Thermolink fibres are not affected by moisture, so ONE PLANET synthetic sleeping bags will keep you warm even when wet. Inside each synthetic ONE PLANET bag are thousands of Thermolink hollow-core fibres, each of which has been heat-sealed at both ends, creating pockets of air within each fibre. These pockets trap warmth even when the sleeping bag is saturated, keeping you cosy all night long.
BAFFLE-LESS CONSTRUCTION
Thermolink fibres are thermally bonded to form structural sheets. We craft these into sleeping bags by shaping them into sleeping bag forms. The thermal bonding of the fibres keeps the fill securely in place without baffles. This improves insulation and warmth and reduces overall bag weight, creating a product that performs better and lasts longer. Cleaning is simple: Thermolink is very durable and can be washed in any standard washing machine.
ZIPS
Every detail counts. ONE PLANET use YKK #5 locking zips with an anti-snag slider. The anti-snag covers make jamming zips a thing of the past, while the YKK #5 zip is more reliable, durable and lasts longer than lower-gauge zips. Using a locking slider stops the zip from creeping open, so it will stay where you want it to for a good night’s sleep.
VAPOUR VENT V2
The Vapour Vent (V2) fabrics are lightweight, breathable nylon with C0 environmentally-friendly water-repellent treatment that promotes hands-free moisture management. The smooth fabrics are light and warm to the touch, ideal for use on multi-day journeys. The tight weave and high thread count ensures they are ‘downproof by construction’. The majority of ONE PLANET bags use the silky, light, 10-denier version both inside and out, while some use the more durable 20-denier option.
DESIGN PHILOSOPHY
ONE PLANET design innovations have led the way since 1980, both locally and globally. ONE PLANET sleeping bags are designed after careful consideration of real sleep – how we lie, move and lose warmth – and real people, with ranges made to fit females and males of all shapes and sizes. ONE PLANET sleeping bags combine 40 years of manufacturing experience with world-leading materials, modern scientific testing and the passion to keep improving.
