The Lightweight Black Hole™ Duffel 45L is the perfect midsized duffel that packs down small but deploys when needed. It held warm-weather clothes for 4 days, a pair of flip flops, a toiletry bag, 32 oz. water bottle, tablet (all shown in the pictures), and had extra room for a fleece, scarf, and small purse, according to a review on Rei.com. The design of the bag makes it easy to spot when collecting luggage off a bus or the baggage claim belt. “It went into the wilderness and returned in good shape,” according to another review.
