Atmos 65 is a premium pack with all considerations taken into account. The airspeed frame wraps around connecting to the adjustable hip belt for an incredibly comfortable carry experience. Be aware that while this pack is designed for premium comfort, The wire frame creating this system is prone to twist and sway when walking if excessively overloaded. Other than litreage, features that distinguish the Atmos AG 65L from the Atmos AG 50L include 2 outer zip pockets for extra storage and organisation. I find attachment points on the outside of the bag, and easy stow hiking pole bungees incredibly useful when out in New Zealand bush, and Atmos a fantastic pack to get me where I need to go!

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!

The Aether 75 is praised as a premium durable pack suitable for heavy load carries by backpackers and mountaineers alike. Osprey's Airscape frame provides the foundation for comfortable carry of more weight and bulk. A stripped back version of the Aether, the Aether Pro trades all external pockets for much larger hip belt pockets big enough to fit a reasonable sized drink bottle, and straps as alternate storage and to synch the sides in when not using the packs full capacity. Great design means that this pack can be stripped down with removable side pockets and the brain of the bag when a more minimalist set up is desired.

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
