(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 the event you’re a chilly sleeper or need a single sleeping bag that may span winter-to-spring or fall-to-winter temperatures, I feel you’ll be impressed by the NEMO Sonic 0’s versatility and luxury.

It additionally contains two pretty distinctive options, which differentiate it from most different chilly climate sleeping luggage: Therm-Gills and Waterproof Ends (footbox and hood).

It’s secured on one facet by velcro and tensioned on the opposite facet with an elastic wire and rope lock that’s straightforward to make use of with one hand when the bag is closed and zippered up.

Two-Approach 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 allows you to vent the underside of the bag when you’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 coming into by means of it. The material alongside each side of the zipper additionally has a material stiffener to forestall the slider from snagging and tearing on the bag’s material which may be very useful on a excessive fill bag.

Extensive Girth

Dimensionally, the Sonic 0 is minimize vast so you’ll be able to retailer additional gear, your boots, or water inside with you while you sleep to forestall them from freezing. That additional width additionally allows you to sleep in your facet or transfer round at evening with ease. If you need to 12 hours in a sleeping bag, you’ll recognize 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 standard arched bag-width mummy hood. The fitted sides imply that the hood strikes together with your face while you flip, providing you with the flexibility to sleep in your facet within the bag, with out drenching the facet of the hood with moist exhalations. NEMO’s spoon-shaped sleeping luggage reworked sleeping bag design by making it doable for facet sleepers to get evening’s sleep so this function is in step with 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-resistant footbox and hood.

When unzipped the Thermo-Gills release some of the warm air trapped in the chest baffles

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 unattainable to succeed in when you had been snuggled inside. Whereas they had been nonetheless helpful, the brand new model of the Sonic provides one other pair of zippers on the within of the bag so you’ll be able to additional regulate your heat stage with out getting chilled.

For instance, when you run your hand down the entrance of the chest (on the within) when the outer or internal zippers are opened, you’ll be able to really feel that the liner is noticeably cooler than on both facet. In the event you’re nonetheless too heat, you’ll be able to 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 nicely they work.

If you’ve ever slept in a single wall tent, it’s common to wake up with a damp footbox
In the event you’ve ever slept in a single wall tent, it’s widespread to get up with a footbox damp from tent condensation. That was the case once I awoke on this single-wall pyramid tent.

Waterproof Foot Field and Hood

In the event you’ve ever slept in a single wall tent, it’s widespread 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 you need to maintain the door closed at evening. However NEMO has encased the Sonic footbox and a lot of the hood in waterproof/breathable material to forestall the moisture from making the sleeping bag’s down insulation moist.

For 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 be vulnerable to condensation switch.

Advice

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 function referred to 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 form of versatility. In the event you wish 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 cheaper 40+ diploma bag or quilt to cowl the hotter months.

Now, the scores for this bag are based mostly on the ISO sleeping bag temperature ranking customary, in order that 0-40 diploma Fahrenheit temperature ranking is sweet for males and heat sleepers. If you’re a chilly sleeper or a lady, the temperature vary will fall between 14 and 40. The distinction is because of the truth that ladies aren’t typically as massive as males and don’t generate as a lot physique warmth. If you’re a lady and wish a 0-degree bag, I’d contemplate the NEMO Sonic -20, which has the identical function set however is rated for colder climate.
