The Lyng -20 Four Season Sleeping Bag: Extreme Cold Weather Performance
The NORTENT Lyng -20 is a serious contender for extreme cold weather camping. Its -20°C comfort rating and -25°C limit rating promise warmth even in the harshest conditions. Constructed with 1.2kg of ethically sourced, DWR (durable water repellent) down, this bag isn't lightweight at 1.8kg, but its superior insulation makes it worth the extra weight.

The bag features a center zip, a rarity that makes getting in and out a breeze. Large toggles on the zipper are easy to grab even with gloves. Additionally, arm zips provide ventilation and allow for easy access to belongings without fully unzipping the bag.

Internal baffles around zippers minimize heat loss. A neck collar, strategically placed baffles on the sides and along the zippers, and an internal pocket complete the insulation package. A unique feature is a large, external Velcro pocket at the foot of the bag, perfect for storing damp items.
NORTENT Sleep Map: Unbeatable Comfort and Packability
The NORTENT Sleep Map is a game-changer in comfort and packability. Its 11cm thickness, generous dimensions (198cm x 68cm), and square-sided design create a luxuriously supportive sleep surface. Despite its impressive size, it packs down surprisingly small, thanks to a clever Velcro pump sack.
The Sleep Map’s 7R value provides exceptional insulation, verified by ASM. Its unique dimpled surface adds another layer of comfort. The design eliminates pressure points, ensuring a restful night's sleep. This is despite its slightly higher weight of roughly 750g (800g with the pump sack).
The square-sided design and robust construction make it particularly comfortable. Its comfort and packability are a significant improvement over some competitors, while its price point is surprisingly budget-friendly, especially compared to other high-end NORTENT gear.
NORTENT Vern 1 Tent: Spacious and Storm-Worthy
The reviewer uses a borrowed NORTENT Vern 1 tent for this test. While not a full review, the video focuses on whether the tent is spacious enough for the reviewer's needs and their gear. The reviewer notes ample interior space, particularly impressed with the headroom and overall comfort.

Even with the sleep map and a down jacket inside, there is enough room for the reviewer to move around comfortably. The tent’s design includes convenient features such as pockets and double doors for enhanced ventilation. However, the reviewer notes that when the tent poles are fully extended, the sloped ceiling might be a bit tight for taller individuals.
The double-door design and robust construction ensure that even in windy conditions, the tent provides great protection. However, the reviewer points out that the storm flaps can make noise in strong winds and might be a minor drawback. Overall, the reviewer is favorably impressed with the tent's spaciousness, features, and weather resistance.
Final Verdict: A Luxurious Winter Camping Experience
The NORTENT Lyng -20 sleeping bag and Sleep Map together create a fantastic winter camping setup. The Lyng -20 provides exceptional warmth, far exceeding the needs of most campers, with thoughtful design features for comfort and convenience. The Sleep Map's comfort and packability are remarkable at its price point.
Both products are robustly built and high quality. Despite their focus on comfort and warmth, they retain relatively packable sizes, making them suitable for various camping styles. The reviewer highly recommends both products for serious winter campers, but notes they might be overkill for milder conditions.
While the Vern 1 tent is spacious, its headroom might be a slight constraint for taller individuals, but overall it's a great tent for most users. The waterproof zippers are a welcome feature for wet conditions, negating the need for a storm flap. The noise of the storm flaps in windy conditions is a minor annoyance.
