Douglaswrote a review of Therm-a-Rest Parsec Sleeping Bag: 20 Degree Down on September 15, 2018
Familiarity: I've used it several times
I've checked this thing out from our "Gear Closet" here at Backcountry 4 times now, it's about time I just pick up my own! The Parsec is very light and packable for how warm it is. 20 degrees is about the perfect do-it-all bag for high alpine stuff here in Utah, but still holds it's own for off-season desert camping. Although it's not really part of the functionality, I really dig the look of the face fabric, props to the designers on taking that into account.
I'd recommend this for anyone looking for a versatile sleeping bag to handle everything you throw at it (other than alpine winter camping).
