In astronomy, a parsec is a unit of measurement used to express the distance between various celestial bodies or objects – like how far the planets are from the sun. Apparently, 1 parsec equates to about 3.26 light years. Which is a very long way away.
But no matter how far you are from home, Therm-a-Rest’s new Parsec sleeping bags are designed to deliver toasty warmth, all night long. And since it’s unlikely you’ll be going anywhere that compares with the intense cold of interstellar space (not much above absolute zero, which is -273.15° Celsius or -459.67° Fahrenheit, in case you were wondering), their premium 800 fill power down should be able to keep you perfectly cosy.
A Trio of Options
In fact, to increase the Parsec’s suitability for a wider range of temperatures and conditions, Therm-a-Rest have also added two more options to the line-up for 2022. Until now, the only bag in the Parsec series was the 20°F/-6°C model, with an EN comfort rating of 0°C (32F) and a lower limit of, you guessed it, -6°C (20°F). That’s the sort of temperature range that makes for a solid three-season sleeping bag, ideal for wild camping and backpacking adventures from late spring through to early autumn.
However, to cater for dedicated winter warriors, there’s also now a slightly bulkier and heavier but significantly warmer Parsec 0°F/-18°C, which is designed to remain comfortable even if you’re out in sub-zero temperatures that drop into double digits.
And for ‘fast and light’ backpacking trips in the warmer months, when either of the two other bags would be overkill, there’s a Parsec 32°F/0°C, intended for nights that could get a little chilly but won’t dip below zero.
Unlike a lot of rivals, all the bags are available in small, regular and long lengths too, ensuring a tailored fit whether you’re 5ft 6 or 6ft 5. In terms of weight and pack size, they’re also very competitive. The regular sizes tip the scales at 685g (32°F), 805g (20°F) and 1,090g (0°F) respectively, with the smallest option packing down to around the size of a 1-litre Nalgene bottle. Therm-a-Rest have also managed to shave a little weight off the new 20°F/-6°C model compared to the previous generation.
They’re all supplied with a compression stuff sack for efficient packing, plus a cloth storage bag that will allow the down fill to loft when not in use, prolonging the life of your sleeping bag.
Who is the Therm-a-Rest Parsec Sleeping Bag for?
With three different bags designed for use in the different seasons, and three different lengths available too, the Parsec range is undoubtedly versatile – it’s a cliché, but there really is something for everyone here.
