This CalPak laptop briefcase is really wonderful .... I looked in some of the large retail stores and nothing compares with the quality and price of this bag ! The outside material is very good quality (strong but not too heavy ). The inside lining material is satin like and also very strong. The shoulder strap is well made with a contoured shoulder pad which also makes it easy to know the way to carry the bag on your shoulder so that the "outside" of the bag in always on the outside. It is very comfortable too. There is lots of room to carry additional papers in the bag, yet overall, the size is not bulky. Lastly, the price is at least $20 less than anything one would find in the store. The delivery was incrediblely fast , just about 2 days after ordering. Thank You Overstock !
