Americans are apparently less outdoorsy than they used to be. Tracking by The NPD Group finds that sales of camping and backpacking items are being largely driven by replenishment. But while people aren’t being drawn to take up camping, there is growth in travel-related items as Americans spend big on trips seen as “experiences.”

Sales within the core U.S. outdoor industry spanning outdoor equipment, apparel, footwear and accessories were $18.9 billion in the 12 months ending April 2018, as tallied by NPD. That’s a decline of 4 percent from the prior year. Despite this topline drop, pockets of growth in areas such as packs, outerwear, and certain camping-related equipment and accessories suggest that adaptable products associated with travel, as well as those tied to replenishment, are bright spots within the core outdoor marketplace.
