At under 1.5kg the fully featured Women's Sirenik 65 seriously punches above its weight. Although one of the lightest weight 65 litre trekking packs on the market no compromise has been made. This pack boasts fantastic load transfer and carrying comfort from the height adjustable, ventilated Women's specific ZephyrAD back system, an extendible/removable lid, double lid closure, multiple storage solutions, including the iconic double front zipped mesh pockets and a base compartment. The Sirenik 65 allows you to ‘pack more’ but ‘carry less’ making it the perfect partner for unsupported stints in the wilderness.

I am 5ft tall and struggle to find a backpack to suit my short back - this was perfect. Should be advertised more for shorter women as its a market that a lot of people miss out on. Taking this to Pyrenees next week and Anconcagua in December so will hopefully have a better review by then but so far its great. The hip belt is one of best in the market as its not as thick and stiff as Osprey and Lowe Alpine ones, the straps are thin allowing comfortable movement but not too thin to rub. Havent packed it up fully yet - had about 9kg in it so far, Anconcagua will be the true test as roughly 17kg will be loaded in.
Its really really light which I was really surprised at coming from a 2.6kg 65+10 rucksack.
The space at the back allows free movement of he head even with a helmet on which is a must for anyone on high altitude expeditions.
All in all so far I am very impressed.

So far, on training hikes of about 3 hours, carrying 12 kilos over rough country, I have struggled to get this pack comfortable. The foam in the hip belt is very firm and the end of it digs into my hip bone. I am fairly broad in the beam (size 16) but the pack seems narrow. I will continue to experiment but am wondering if the men's version would have been better. Hopefully it won't end up on Ebay! I will recommend the product, with the caveat that you are of slim build.
