More info

GOSSAMER GEAR Gorilla 50 - is a top loading backpack with a total capacity of 50 liters (including extension collar), with 32 liters of space in the main compartment and the rest divided among the pack’s other pockets. 

According to Outdoor Gear Lab’s Editor’s Choice it is the best mid-volume light backpack. Its versatility, durability and comfort make it the best weekend companion you’ll ever have. Also works on longer trips and through hikes with itineraries including grocery/laundry opportunities.

The main compartment features an internal hydration sleeve to hold a hydration pack with a hang loop at the top for securing it and two hydration ports located above both shoulder straps to let you route the drinking hose over either shoulder.

It is made of Robic nylon fabric. 100D Robic nylon is used for the main pack and thicker more durable and abrasion-resistant 200D Robic nylon in critical areas - bottom of the pack and the side pockets. Robic fabric is waterproof and sheds water well in rain, but the backpack is not completely waterproof and leak at the seams which are not sealed, so we recommend to use waterproof stuff sacks or line the pack with the plastic bag to protect your gear against rain and moisture.

How to Attach Hiking Poles to Your Mariposa? For attaching trekking poles hiking poles, an umbrella or other gear to your pack you can use Lightrek Pack Bungee Attachment (sold separately).

Read detailed Review from Outdoorgearlab:

"This model is the best do-everything ultralight backpack we tested. When we needed to carry winter gear and five days of food on the Appalachian Trail in January, it was just the right size. When we wanted to strip it down for day hikes or one night out in the wilderness, the frame and waist belt were easily removable. The exterior storage pockets were also perfect for our testers, keeping snacks, water bottles, and extra clothing layers easily accessible. Whether you're thru-hiking for months or playing in the backcountry for the weekend, this pack is perfect."
