Traveling light for a short ski trip requires a simple backpack. It needs space for a spare shirt and pants, your computer, and a few other compartments for things like shades, a jacket, beanie, headphones, and water bottle.
The travel pack also needs to be versatile and not too trendy so that you can actually take it for a jaunt outside. The below packs are a collection that travel well via plane or on the commuter bike, can be used as a work bag, gym bag, or both, and in a pinch can play double duty on the trail.
Considering a 30-liter backpack is big enough for shredding, the Dakine Concourse will easily handle any short getaway. The top loader flips open for easy stuffing, and can be accessed via a side pocket with an additional top-flip loader compartment for sunglasses and other accessories—so they don't end up at the bottom of the bag. The computer sleeve is padded and easily accessible for that chaotic TSA line, and has a multitude of other pockets to make it a slick work bag as well.
The Greenland Top from Fjallraven may look like a hipster version of your old Jansport school bag, but the brand's patented G-1000 water-resistant material differentiates it from those OG knapsacks. Fjallraven's Greenland Wax can also be added to enhance the waterproof protection. It has a minimalist design with a flip top drawstring closer, and is more suited for work and commuting, as the shoulder straps are a wee-bit thin for hiking. However, it can be used for quick overnighter trips via plane given how light and easy it is.
Featuring a similar flip-top design like the Concourse, the 21-liter Robo Flip is perfect for work and play. It has an internal water bottle sleeve, and a padded laptop holder along with a tablet pocket. Mystery Ranch’s burly nylon fabrics hold up to most abuse, be it a bumpy bike commute or post-work hike in the drizzle. It also can adjust to the amount of load with side compression straps.
