I. Introduction Gregory's backpack is divided into three series of pro series (previously known as expedition series), Adventure series, escape series, the design is different, the appeal is not the same, will be introduced later, Gregory backpack's characteristics as their motto - Fit is -everything, so they respond by providing different sizes and replaceable shoulder straps and waist straps so that each user can choose a backpack that fits his own. The design of the piggyback system is simple and straightforward, but there are many small organs that are adjustable, including shoulder width, back length, belt angle, etc.; Second, Adventure Series: There are five models in active service, Wind River, Whitney, Palisade, Shasta, Lassen. The belts and shoulder straps of flo-form II are used. The back bag is composed of 210d double-lined mesh nylon cloth. 420d), Skeleton uses 2 X 7075-T6 0.75 Aluminium Bar (Before 2001 used 2 X 2024-T4 1 Aluminium Bars), a thick waterproof rubber at the bottom and back, and the back of the backpack is designed to have two connected back cushions , The internal filled with similar electrical shockproof foam material, will not absorb water, the overall air-weight than the pro series light 0.75-1 kg, but the strength, back and comfort is still not as pro, the price is relatively low, the top cover can also be Removed from the pockets, in 2002 this series made a lot of lightweight efforts in an attempt to get rid of gregory empty weight too bad notoriety. Three, Escape Series Belonging to the backpack category, although the largest Forester has achieved 75L, but the original design of the upper limit of 40lb, 2002 from large to small have Forester, Reality, Gravity, Chaos, Banshee, Fury, 2003 new models for Forester, Reality , Acadia, Deva, Siren, where Deva and Siren are narrow back versions designed specifically for women; the interior is a single 7001-T6 aluminum strip (6061-t6 before 2001), screwed onto a human hard plastic plate, In the two years, the material has gradually changed from 420d to 210d. The top cover must not be used as a hip pack. The stealth shoulder strap and wildness belt (Banshee & Fury uses a fixed belt) have weak support and the back design is similar to the Adnenture series. Filled with foaming material, the back is less than 15kg fashionable and comfortable, it will be slightly deformed when it exceeds 20kg. Fourth, shoulder straps and belts The three series of shoulder straps and belts are divided into two types: Flo-Form II (Pro & Adv series) and Stealth (escape series): (1) Flo-Form II's shoulder strap: The shoulder straps do not belong to the heavy type. Compared to many U.S. backpacks, they look thinner and narrower. Using special patented technology, heat treatment makes the S-type foam, and the foam they use is said to be It is the highest grade, coupled with unique sewing techniques, that does not allow any sutures to pass through the foam, it can make the foam will not be elastic and fatigue (the personal ten years of experience is also the case), after a long time there will be suitable for you The shape of the individual (individuals agree very much with him, so the backpack does not borrow); there is a thin plate on the shoulder strap and under the devil felt, this feature can be used to adjust the shoulder width to achieve the best fit for everyone's body shape; Bring the original iron buckle, can be adjusted up and down, so that the edge of the strap with the rain backpack force angle to perfect, so the backpack will be closer to bear the stress center. In the past five years, Flo-Form II has begun to cooperate with the Auto-Cant system. Prior to this, the shoulder strap was directly connected to the backpack body, and the adjustable distance was longer. There were three compartments at intervals of 1 ft.; the new generation system was added auto. -Cant, the design principle is simple. It is connected by a rotating plastic steel plate and a backpack. The main purpose is to use its natural rotation principle. When everyone back, they will turn out the most suitable personal angle for Best Fit, but you can Fine-tune the grid spacing into two compartments, every 1 mile. (2) Flo-FormII Belt: The construction method is the same as that of the shoulder strap. The material is made of a high-density, high-density foam. The hard plastic version connected to the skeleton of the backpack is particularly mentioned. Many people who like or hate Gregory are because of this so-called rigid belt. This one-of-a-kind design is unique in that most of the weight of the backpack can be borne by the waist belt. When using it feels tight, it is the largest waist support force in the backpack I have tried. It is also due to his hard and many uses. The person is not accustomed to it; there is another characteristic of the waist belt. There is a screw on the inside and you can adjust the angle of the belt (three segments), called adjust-a-cant, to match each person's different waist to hip ratio. (3) Stealth harness & Wildness waist belt: The use of three layers of foam with different densities and hardness, thickness and width than the Flo-Form II, but the bearing capacity and support force are not as good as Flo-Form II, but the use of the system such as the escape series, the original design The shoulder straps are not adjustable. The shoulder straps are not adjustable in shoulder width. The straps are also connected to the backpack by the Auto-Cant. The angle of the belt is also not adjustable, and there is no rigid plate support, so the waist is not as strong as the Flo-Form. II. The connection between the belt and the backpack body is through the hard plate on the back of the backpack and it is not connected to the skeleton.
