A comfortable women's-specific pack that gives you the ventilation, hydration and protection you need for hiking the trails.

The Osprey Sirrus 36 Rucksack is made from tough materials but it's lightweight and low-bulk, and shaped to fit the female form to stay stable on your back.

There's an internal sleeve for your hydration bladder, so you can stay refreshed on the move. The AirSpeed™ trampoline mesh style back system, spacermesh harness and hipbelt all work together to keep you comfortable and cool even when you're working hard. Cleverly designed ice axe/walking pole storage lets you carry what you need without fuss. And an integrated raincover pulls out in seconds to keep your gear protected when the weather turns sour. 

The main compartment is easily accessed when you're moving, and has excellent internal organisation so your kit stays where it should. On longer trips, you can attach a sleeping pad to the outside and put your sleeping bag in the base. And there are a wealth of pockets inside and out, with compression to stabilise the pack and stop it from 'rolling' around your back.

It's a pack that lets you concentrate on your hike, not on what you're carrying.

Osprey Sirrus 36 Womens, 11 September 2016
By Tommy's mum (Essex)
I needed a decent rucksack as I was doing a fundraiser walk of the Norfolk coast with my dog a colleague recommended Osprey. Excellent, plenty of pockets, comfortable, I wore it every day for a week and suffered no aches and pains in neck and shoulders which I have experienced before when wearing a less structures ruck. Highly recommend this product and the fact it was in a lovely purple too rather than navy was a added bonus.

Love it, its comfortable to wear. Loads of room, lots of pockets. Like the colours available. Love the fact that it has a rain cover with it.

Best pack ever!, 05 May 2016
By Shaznay999 (Blyth, Northumberland)
I spent well over an hour with Naomi at the West Denton store to select the best pack for my height and size and more importantly, for the job I needed it to do. This pack is undoubtedly the most comfortable, well made ruc sac I have ever owned. I can comfortably fit everything in that I needed for a full day's hike, including 1.5 litres of water in the hydration kit. In essence, it fits so well, you forget that it is actually on your back. I am a lady hiker (5ft 3in). There are the most useful pockets at the sides of the belly strap - ideal for easy access to your mobile or small GPS. Great product.

It's even in my favourite colour......, 21 March 2016
By Flipper (Wisbech)
I have been researching rucksacks for a while and Osprey got a lot of good reviews. I have had shoulder and back injuries so it’s important I get a good fit. This is the best fitting rucksack I have ever bought. I do a lot of power walking and at present I am training with the rucksack weighted. It does not move around like my previous one. There are more compartments than I have things to put in them. Great to have the ability to carry my poles. It cost a bit more than I was going to pay but it was well worth it. Great piece of kit and although it’s in my favourite colour this was not the governing factor, just lucky.

It's perfect !, 28 December 2015
By Mac (London)
Excellent rucksack, perfect fit. I had my old rucksack for a number of years and it was hurting both my back and shoulders on long walks. I had a 10 day trek coming up so decided it was time to buy a new one. I did a good bit of research and the Osprey came up as fitting the bill. I honestly cannot fault the rucksack in any way. Firstly, after walking each day for around 10 hours and carrying around 6-7 kgs my back and shoulders felt great. I have a bad back and this rucksack didn’t cause any discomfort. The shape is brilliant, v neat, the straps mean you can tighten it all up. The two ways of carrying the poles are great too. The waist band sits just right on the hips for added comfort. Another great feature is the front opening – no more pulling out your gear from the top of the bag, everything can be accessed easily. The bag is so well thought out and well made, even the pulls on the zips are perfect. They have large plastic loops so you can really easily pull them even with gloves on. The bag is really light too. One last advantage is that there aren’t lots of straps, loops or elastic hanging off that you’ll never use. Definitely gets 5 stars
