Sizing is different and listed as Women's S/M which is in between the current 2 sizes. Backpack straps are velcro adjustable at the top. This was only used in the house...just couldn't get the fit quite right so essentially new. However, there is some mild discoloration on the back panel that developed from the adhesive that was used (See last few 2 photos). Contacted the company, but considered a cosmetic defect only as it does not affect the use and is not sticky. There is mesh over the area as well. Slight discoloration of right hip mesh pocket (see 3rd to last photo).
