While not the lightest ultralight pack on the market, Exos is definitely one of the most comfortable! With the airspeed frame providing great airflow between the bag and your back, this is a great stepping stone for those making the switch to ultralight while maintaining some of their classic gear. The classic drawstring top opening has a twist, with the ability to detach the brain for shorter trips. Quickdraw hiking pole storage and all the pockets you'd expect, It's no wonder this pack is a hot seller!

At under 1Kg, this is one of the best ultralight back packs on the market! Balancing weight and comfort perfectly, Exos Pro 55 is minimalist in design while keeping all the handy feature you want while hiking. Front pouch, dual access drink bottle pockets and hip belt pockets are included. While the pack still has the brain of the bag protecting the drawstring opening, this too can be stripped off with a small flap taking it's place for protection from the rain. Ideal for the speed and comfort combo on long multiday hikes, or the likes of Te Araroa trail. Ultralight material by its nature, is thinner, lighter and less abrasion resistant. As long as off trail bush bashing isn't in on you itinerary, this is a great light weight pack choice!

One of, if not, the best fitting harness I've tried on. Hugs the hips really nicely and has enough structure in the hip belt that you don't need to pull it overly tight. Compression straps in every place you could need them and tie on points for overflow of gear and hiking poles or ice axes. Side access zips make it convenient to pull out anything from just about any place inside the pack. Favorite features by far are the front access to the water bottle sleeves or the overflow pocket on the front that makes a great spot for a wet shell jacket.

Fit tip:

Definitely get fitted in store
