The Sirrus 44 is a great pack to choose if you are looking at the 36L and thinking you just need that extra space or if you are simply thinking on taking it on a one to two night tramp. The 44L is an ideal volume if you don't want to overpack and like to carry less or if you are mostly staying in huts. The Sirrus uses the Airscape back technology which allows more airflow through your back. This in turn can cause some people to feel like the shoulder straps are pulling on the collar bone as the pack is naturally going to sit further away from your back.
This model is good if you are going to be using it in summer or hot countries where you know you will want that airflow and comfort.

Fit tip:

Multiple torso lengths. Sits further from your back.

I am excited for the Tempest Pro to be my future multi day lightweight tramping pack. The 40L volume offers that sweet spot between enough space to fit your belongings as well as keeping you from overloading yourself and carry less. The "Pro" version of the tempest is a more streamlined version of the 44L. It has less padding on the shoulders and hip belt and less straps hanging about and it is made from lighter weight materials. The pack sits closer to your back the same way all Tempest/Talon range packs do, which is better for fast hiking, going on uneven and steep terrain as it keeps the pack from swinging side to side or having a sensation that the weight of the pack is pulling you backwards and destabilizing you. If you are looking for something more padded and comfy, this is not the pack for you.

Fit tip:

Close to your body. Comes in different sizes.

This is my go-to pack on long Winter hikes when I need some extra volume or on quick overnight missions. This pack has come with me to Cape Brett lighthouse, Pouakai Tarns, and many others. This pack does better with a lighter load as it has minimal padding, and the adjustability in the shoulder straps/hip belt is more limited compared to other packs. I love how this pack carries weight close to the back and the harness hugs around the hips/lower back - but if you have wider hips this may not be the pack for you! The one thing I don't love about this pack is the load adjusters on the shoulder straps - if your pack is on the heavier side you'll definitely start to feel it which is why it's suited more to lightweight trips.

Fit tip:

Suits narrower hips
