Mummy shaped bags
The Cocoon and Winter Lite are One Planet’s mummy-shaped bags, and the most thermally-efficient bags in our range. Designed to hug your body shape, these bags give the most warmth for their fill but have the least internal space. A combination of vertical and horizontal baffles is used, preventing the fill from shifting during use. The vertical chest baffles, which run from the neck to the waist, prevent the down from drifting from the highpoints of the bag (created by your torso) down to the sides of the bag during the night, causing cold spots. The baffles are also ‘sewn-off’, which prevents the fill from moving from the top to the base of the bag. However, this means the fill cannot be shifted as conditions dictate. The Winter Lite has a zip which runs the full length of the side whilst the Cocoon only has a half zip.
The One Planet tapered rectangular bags provide a combination of efficiency and comfort, allowing more wriggle room and versatility but with an increase in size and weight. Most of our tapered rectangular bags use vertical chest baffles to keep the fill where it is needed. However, the Booster, Camp Lite and Stowaway use V-shaped baffles, which prevent the down from moving more efficiently than the traditional horizontal baffle while still allowing it to be moved within the bag to suit conditions.
The One Planet tapered rectangular range includes the Booster, Bungle, Bush Lite, Camp Lite, Stowaway and Zephyr down bags, as well as the whole synthetic range.
Rectangular bags are spacious and comfy, with the good old rectangle providing extra space for those who really like to move. Our versatile, cosmopolitan Robin Hoodless is designed for car-based camping or travelling where packed size and weight are less of an issue. In these conditions, there’s no need for a technical hood so we’ve removed it – the hood is a sleeve only, so a pillow can be inserted and will definitely stay put. V-shaped baffles help prevent the down from shifting unintentionally, whilst it can still be moved from top to bottom as conditions dictate. When unzipped, this style of bag makes a great queen-size doona: perfect for when you’re staying put for a while and want the comforts of home.
