We searched long and hard to find a travel backpack with all the features that we really care about, and we couldn't be more excited to share it with all of you.  Our favorite feature of this ultra lightweight backpack is that it weighs just over half a pound, and it fits inside the included stuff sack for easy travel.  We like to travel light and bring a lightweight bag with us that we can fill with additional items we've acquired along the way, and this pack does that and much more! With a capacity of 35 liters, this pack is a spacious day pack.  You can put your Retreat Outside insulated water bottle in the storage pocket on the side of the pack, and there's plenty of room for your cell phone, gadgets, and clothing inside. Did we mention this backpack is also waterproof?! After all the years we spent in the Pacific Northwest, that's a feature we had to include.  That way, you don't have to worry about your belongings getting wet on those rainy days. We're digging the vibrant blue color, sleek design, and minimal footprint.  Take this handy pack on your next adventure; whether it's a music festival, day hike, or a trip to South America, you'll be glad you have this versatile companion.
