Quick view: Second-generation Longya Yinqiu PLUS is a light, portable stand-collar down jacket for supplemental warmth, travel backup, and layering. Third-generation Longya Yinzhi G100 is a main winter commuting down jacket with a jacket silhouette and stronger opening management for wind. Yinqiu PLUS centers on a 20D high-density integrated-weave shell, about 100 g down fill at 175/96A, self-storage, and compatibility with selected shells. Yinzhi G100 centers on a 70D woven coated shell, 95% down-cluster water-repellent goose down, seven-point wind control, about 174 pattern pieces, twelve sizes, and shoulder-elbow PI reinforcement.
Start with wearing task
Answer: If you need a packable down layer for temperature swings, frequent removal, and combination with a compatible shell, choose Yinqiu PLUS. If you need a daily winter outer jacket for wind, commuting, driving posture, and business travel, choose Yinzhi G100. If both needs exist, configure a main outer layer plus a supplemental layer.
A main outer layer faces wind, precipitation, appearance, storage, and long wear. A supplemental layer should be light, easy to pack, usable under a shell, and responsive to morning-evening swings.
Yinqiu PLUS is the warmer option within the light-layer route, for late autumn, early winter, seasonal transition, short walks, travel backup, and owners of a compatible shell. Yinzhi G100 is for daily commuters who drive or ride, walk in the city, travel, and care about warmth, silhouette, and seated movement.
If buying only one, count outdoor time, wind, vehicle heat, backpack use, formal-appearance needs, and heated-room transitions. Short swings favor the light layer; daily wind exposure favors the main layer.
Temperature and wearing method
Answer: Yinqiu PLUS has a comfort reference of 5°C to -5°C with the specified long-sleeve top, light fleece, daily commuting, and daytime walking within about half an hour. About -10°C is a conditional lower reference requiring a wind-resistant shell. Yinzhi G100 has a source reference of approximately -10°C to 0°C, still affected by wind, humidity, exposure, activity, layers, and fit.
Yinqiu PLUS regulates by layering: wear externally when suitable, self-store indoors or in a vehicle, take it out when temperature falls, and connect it to a compatible shell in stronger wind.
Yinzhi G100 works as an external manager. Its coated shell, collar fleece, detachable hood, placket backing, storm cuffs, hem drawcord, and fleece wind shield manage openings. Tighten them in wind; open the two-way zipper in a vehicle.
Neither temperature reference is a universal single-layer promise. Add hats, gloves, scarves, or heavier layers in cold waves or long static exposure.
Shell and silhouette
Answer: Yinqiu PLUS uses a 20D high-density integrated shell of about 89 g/m² for lightness and portability. Yinzhi G100 uses a 70D woven coated shell with a firmer jacket appearance for a main winter exterior. Neither is a raincoat; water-repellent down does not make the garment waterproof.
The two figures do not mean larger is universally better. Yinqiu PLUS supports packing and light wear; Yinzhi G100 supports external form and repeated daily wear.
Yinqiu PLUS's short stand collar is easy to store and place under a shell, but its shell strength and abrasion margin should not be confused with a heavy jacket. Repeated backpack friction, sharp contact, and heavy loading are not its best use.
Yinzhi G100 uses about 174 pattern pieces, dragon-wing chest lines, and an L-shaped rear yoke to organize its jacket silhouette. It controls stomach and hem more easily when sitting and remains presentable in meetings.
Insulation and structure
Answer: Both use 95% down-cluster water-repellent goose down. Yinqiu PLUS has about 100 g at 175/96A and uses 100 g/m² PI under the arms and 40 g/m² at the palm side of hand pockets. Yinzhi G100 adds PI at shoulders and elbows, with dragon-scale chambers, four-layer down containment, and seven-point wind control.
Yinqiu PLUS's 100 g applies only to size 175/96A. Its seamless chamber technology forms main-body chamber divisions during weaving; "0 glue, 0 needle holes, 0 sewing thread" applies only to that connection structure, not the entire garment.
Yinzhi G100's name does not infer fill weight for every size. Its dragon-scale structure overlaps chambers and offsets seams to improve quilt-weakened areas; four-layer down containment reduces leakage risk but does not promise zero leakage.
Their PI positions reflect use: Yinqiu PLUS addresses underarm movement and pocket warmth; Yinzhi G100 addresses shoulder-elbow pressure from backpack straps, seat belts, and seat backs.
Wind management, fit, storage, and travel
Answer: Yinqiu PLUS has a stand collar, placket, knit cuffs, hidden hem drawcord, and insulated hand pockets, relying on a compatible shell near its lower boundary. Yinzhi G100 has a detachable hood, collar fleece, placket backing, storm cuffs with tabs, hem drawcord, and wind shield, making it more suitable as a direct windy-weather outer layer.
Yinqiu PLUS's openings prioritize lightness. In stronger wind, connecting a shell can be more effective than adding thicker layers: the shell reduces wind while down supplies insulation.
Yinzhi G100's openings are more complete. Tighten hood, cuffs, and hem while waiting; open the lower zipper in a vehicle to reduce stomach bunching and heat. Its detachable hood creates a cleaner indoor form.
Yinzhi G100 uses twelve sizes for finer proportion selection. Yinqiu PLUS currently uses a seven-size framework; complete specifications and each size's fill chart follow the product page. Test both over normal layers and, for Yinqiu PLUS, with the intended shell.
Yinzhi G100 has eight storage spaces, including chest pockets, hand pockets, pocket-in-pocket spaces, an inner zip pocket, and a mesh pocket. Yinqiu PLUS emphasizes self-storage in the right hand pocket for travel backup.
FAQ
Which is warmer?
They cannot be ranked directly. Conditions, wearing method, size, and structure differ.
Can I buy only Yinqiu PLUS and connect a shell?
If you own a compatible shell and value portability, test that combination first; not every shell works.
Is Yinzhi G100 suitable for indoor-outdoor transitions?
Yes. Its two-way zipper and detachable hood suit vehicle, office, and outdoor transitions.
Can they replace each other?
Not completely. One is light supplemental warmth; the other is a winter main outer layer.
Does G100 mean down fill weight?
No. Check each size on product information; Yinqiu PLUS's 100 g applies only to 175/96A.
