The NEMO Sonic 0 is a down-insulated sleeping bag that may be comfortably used from zero levels Fahrenheit as much as 40 levels. (That is the 2022 model which has been considerably up to date from earlier fashions.) Whereas the Sonic 0 can be utilized as a winter sleeping bag and has all of the superior options you’d anticipate, it has particular thermo-regulation gills on the chest that allow you to vent it in hotter climate. In case you’re a chilly sleeper or need a single sleeping bag that may span winter-to-spring or fall-to-winter temperatures, I believe you’ll be impressed by the NEMO Sonic 0’s versatility and luxury.

Sleeping Bag Options
The Sonic 0 has all the normal options you’d anticipate on a premium chilly climate sleeping bag, together with a draft collar, two-way aspect zipper, zipper draft tubes, taped zipper stiffeners, spacious dimensions, and a really heat hood. It additionally consists of two pretty distinctive options, which differentiate it from most different chilly climate sleeping luggage: Therm-Gills and Waterproof Ends (footbox and hood).
Draft Collar
The draft collar is a down-filled tube that drapes over your higher chest and neck and round your higher again to seal within the warmth generated by your decrease physique. It’s secured on one aspect by velcro and tensioned on the opposite aspect with an elastic twine and rope lock that’s straightforward to make use of with one hand when the bag is closed and zippered up.
Two-Means Zipper and Draft Tubes
There’s a 3/4 size two-way zipper that begins above the footbox and runs all the best way to the hood. Having a two-way zipper enables you to vent the underside of the bag for those who’re too heat. The zipper has two draft tubes (most luggage solely have one) that run alongside the zipper and fold collectively to dam any drafts from getting into by it. The material alongside either side of the zipper additionally has a cloth stiffener to stop the slider from snagging and tearing on the bag’s material which could be very useful on a excessive fill bag.
Extensive Girth
Dimensionally, the Sonic 0 is reduce extensive so you may retailer further gear, your boots, or water inside with you if you sleep to stop them from freezing. That further width additionally enables you to sleep in your aspect or transfer round at evening with ease. If it’s important to 12 hours in a sleeping bag, you’ll respect the additional room!
Mummy Hood
Whereas the Sonic 0 has a mummy hood, it’s formed extra like a jacket hood with close-fitting sides than a extra typical arched bag-width mummy hood. The fitted sides imply that the hood strikes together with your face if you flip, supplying you with the flexibility to sleep in your aspect within the bag, with out drenching the aspect of the hood with moist exhalations. NEMO’s spoon-shaped sleeping luggage reworked sleeping bag design by making it doable for aspect sleepers to get evening’s sleep so this characteristic is according to their core DNA.
However there are extra differentiating options on the Sonic 0 that you simply simply gained’t discover on different comparable sleeping luggage, together with the Thermo-Gills and a water-proof footbox and hood.
Thermo-Gills
Thermo-Gills are lengthwise zippered channels sewn over the chest of the Sonic 0 that launch a few of the heat air trapped within the down baffles with out letting drafts in. Earlier variations of the Sonic had these zippered channels on the skin of the bag solely, which made them not possible to succeed in for those who have been snuggled inside. Whereas they have been nonetheless helpful, the brand new model of the Sonic provides one other pair of zippers on the within of the bag so you may additional modify your heat degree with out getting chilled.
For instance, for those who run your hand down the entrance of the chest (on the within) when the outer or interior zippers are opened, you may really feel that the liner is noticeably cooler than on both aspect. In case you’re nonetheless too heat, you may loosen the draft collar and let further warmth out. I’ve taken the Sonic 0 as much as the mid-forties (F) utilizing these temperature regulation options and have been actually impressed by how effectively they work.
Waterproof Foot Field and Hood
In case you’ve ever slept in a single wall tent, it’s frequent to get up with a sleeping bag footbox or a hood that’s damp from tent condensation the place they contact the partitions. It’s additionally a typical incidence in winter tents, particularly when it’s important to hold the door closed at evening. However NEMO has encased the Sonic footbox and a lot of the hood in waterproof/breathable material to stop the moisture from making the sleeping bag’s down insulation moist.
As an example, I’ve slept with the Sonic 0 in three totally different single wall tents and observed water droplets on the skin of the footbox each time. Whereas the outside material is well dried by placing it out within the solar whilst you make breakfast, it’s good to know that the down insulation, which might take longer to dry, hasn’t gotten moist and can retain its loft, particularly on a multi-day journey. It’s the identical with the hood, which can also be susceptible to condensation switch.

Suggestion
The NEMO Sonic 0 is a cold-weather down-insulated sleeping bag that has a a lot wider temperature vary than its title would recommend. Whereas it’s designed to maintain you heat in 0-degree climate, it has a temperature regulation characteristic known as Therm-Gills that allow you to vent heat as much as about 40 levels. I can’t consider another cold-weather sleeping bag with that sort of versatility. In case you prefer to winter camp however wish to prolong the season into early spring or autumn, the Sonic 0 is a wonderful choice. You’ll be able to then purchase a a lot inexpensive 40+ diploma bag or quilt to cowl the hotter months.
Now, the rankings for this bag are primarily based on the ISO sleeping bag temperature score normal, in order that 0-40 diploma Fahrenheit temperature score is sweet for males and heat sleepers. If you’re a chilly sleeper or a girl, the temperature vary will fall between 14 and 40. The distinction is because of the truth that girls aren’t usually as massive as males and don’t generate as a lot physique warmth. If you’re a girl and want a 0-degree bag, I’d think about the NEMO Sonic -20, which has the identical characteristic set however is rated for colder climate.
