JanSport Cirque Spring 1998 Catalog Cover, I designed the bag not the catalog.
JanSport Cirque, and Couloir
JanSport Traditionalist and Extremist. The Extremist is an obvious spin off from the Traditionalist. I believe that the Traditionalist was already designed, probably by Jerry Parker, but I think that I did all the product development on this style.
JanSport Alpine Day and Alpine Trek. I don't remember how much of the design I actually did on these two bags, however I do remember making one of the first samples for the Alpine Trek I believe. Did all the product development and managed the manufacturing of this bag out of Costa Rica. - Saw the biggest spiders I had ever seen at a place called the Zoo Ave in Alajuela Costa Rica. They were 3" to 4" in diameter. When I asked the guide if they had a lot of big spiders in Costa Rica, he laughed nervously, and said that he hoped not, as this was the first time he had ever seen anything bigger than common house spider.

I designed these packs in collaboration with Jerry Parker who was the Product Line Manager for Technical Packs at the time. Absolutely loved working with Jerry he was the best, and we did a lot of great work together.

Many of the designs were also influenced by Jan Lewis one of the founders of JanSport and still the primary design influence at JanSport in 1998
