An insulated jacket should fit snugly to your body. It is important that the jacket be allowed to bend completely so that hot air can be trapped. Insulation simply does not work when compressed. You can also leave some room underneath for extra layers when it's really cold.
A properly sized down jacket should have a snug fit to prevent air from entering and, at the same time, not restricting its movement in any way. It should also not feel tight in the chest, shoulders, or arms, nor should it expose the stomach when the arms are raised above the head. Insulated jackets are pedantic little things. Too tight and you'll compress the insulation and limit the warmth capabilities of your new jacket, too loose and you'll spend hours warming up the dead space inside the jacket.
Getting the right fit isn't just about aesthetics, it will determine how hot you are. It should fit close to the body if it is not placed much under it. The fit should be close enough, but not compress the down with full range of motion on the arms, shoulders and chest. I think it's weird that the GW stays.
Tight in the chest and shoulders, loose in the belly and long in the arms. However, it could be my body type. You don't want something baggy, but it shouldn't be restrictive or tight for you. If it is too loose, it will get in the way a lot and it will take longer to warm up.
Being restrictive has obvious problems. And if it is too tight, the insulation is compressed and can not do its job. A down jacket should not be too tight or too loose. You should allow layers to be added underneath, but make sure that it is not too roomy, as cold air could enter through the hem and arms.
Down jackets tend to be heavier than regular waterproof jackets or fleece coats, so remember that you need a little space to move. We're not going to get into the thick of it here, but you should know that a sewn down jacket will almost always be less warm than its baffle box brother. In addition to aesthetics, it is important to know if your down jacket fits you, as it will not insulate as effectively if it is too big. Additional fabric is added, which means that it can be heavier than a jacket with the stitched method, and because additional fabric is used and the technique is more complex, items with box baffles are often more expensive.
You also don't want the jacket to compress because it is tight, since its swelling is what makes it effective. That said, sometimes this is part of the jacket style, but other times, it means excessive space where bad air pockets hang out. However, in addition to the right fit, there are also other factors to consider when it comes to an excellent down jacket. Two different types of down jackets contrast sharply both in cost, comfort and significant level of warmth.
Remember that your down jacket should have a solid layer of insulation between you and the jacket; however, if that layer is too big, it will end up being colder. I have separate, much heavier puffy jackets that can fit over a fleece, plus a quilted layer, plus a soft or hard layer, for deep winter and ice climbing. It has become very fashionable that box deflector jackets on the market have extremely narrow boxes filled with down. When I say airbags, I don't mean the protruding folds, bulky folds and open jacket hems - these are the defective air pockets that provide too much space for air to circulate and cannot effectively heat the entire area.
The fit of a winter coat should not be too wide, or it will not insulate as efficiently as a well-fitting coat. Worn by everyone from Kanye West to Daniel Craig, down jackets can trace their origins back to the 1930s, when American nature lover Eddie Bauer nearly died of hypothermia on a fishing trip. With only one shirt on, I plan to size them the same way I would fit a blazer or a light city jacket, cropped but not tight. Between the inner and outer lining, the down is filled into the jacket before being sewn directly onto the lining, hence the sewing category.
