As the name suggests this is an excellent wee bag to take out for the day. The Arbor 20L Daypack in Joya Blue is perfect for the day because Patagonia have made it incredibly comfortable to wear for long stretches at a time due to the human curved straps. The material is also incredibly durable due to the tough polyester weave which has then been complimented with a water proofing layer. Perfect for cutting about the streets of Glasgow!
