The Ultra-Sil™ Day Pack won the Backpacker Editors' Choice Gold Award in 2017, meaning this little pack has stood the test of time and sustained its best-in-class status for more than 5 years. It is perfect for a summit pack, carrying groceries when on foot, on a bike or as an extra traveling tote. The tiny packed size of this perennial bestseller fits easily onto your key ring, in a jacket pocket or a purse. Reinforced bar-tacks at all stress points enable it to withstand loads many, many times its own weight.
