The Helly Hansen Guide 22L Daypack sheds drizzle on the walk to work, thanks to 600D polyester ripstop with a thermoplastic polyurethane coating. YKK AquaGuard zippers extend that water resistance to the closures. The combination suits rainy commutes and damp trailheads. What Our Gearhead(R) Experts Are Saying:"On a rainy commute, the dedicated padded compartment keeps my laptop away from the wet umbrella and damp jacket in the main compartment. The padded back panel adds cushioning when the pack gets shoved under a train seat."
