This is the first twin somewhat sophisticated than jachète for a long hike it is still a bit heavy but it is still light for this type of binoculars, and the bag is provided. Maybe one expert would find fault but in any case, as the first purchase that's great, I'm already used it several times for animal observation, the picture is very beautiful and the development easily adaptable to the eye left and right. At value I think it is part of the best articles of this type.
