Explaining the Fit of the "Karrimor" Backpack "Contour 27" Achieved Through Seamless Adjustment

About 50 years ago in 1975, the backpack used by Junko Tabei, the first woman to successfully summit Everest, was a product of "Karrimor." "Karrimor," which significantly contributed to the development of modern mountaineering, shocked the world in 1983 with its "SA System" technology.

This system, which had been used exclusively for large backpacks until recently, has finally been incorporated into the "Contour 27" this year, a size convenient for low mountain hikes.
 
This is groundbreaking. Without exaggeration, it will greatly enhance the comfort of hiking and trekking. We promptly visited Karrimor International Ltd. and asked Kota Matsunaga from the product team about the outstanding features of the "SA System" and "Contour 27."

"Our original 'SA System' is a back adjustment system announced in 1983 as the 'world's first size-adjust system.' It's crucial to choose a backpack with an optimal back length; for example, even with the same capacity, sizes may be divided into L, M, S, etc., depending on the back length.
 
"Rather than dividing sizes by back lengths step by step, a product that covers the entire range with back adjustments fits individual users with one size. The 'SA System' is the technology that makes this possible. Developed because fit is most important when carrying heavy loads, it has been used in large backpacks."
