We Like
- A 150 gram daypack! Drop your main pack when you go off trail and take just the essentials to minimise the weight you carry and reduce the impact on your body
- Water bottle carrier so you can take what you need rather than a large bladder. Less weight on you
- One size fits all means that anyone in your family and group can carry this pack making it very versatile
- No waist band required with such a light pack further reducing the weight you carry and minimising the impact on your body
We Don't Like
- Being so lightweight can also be a negative as durability is going to be an issue if you are rough with your gear or go bush bashing
Osprey Ultralight Stuff Pack Review
In 2017 we walked the Overland Track and it’s common practice for a number of the side trails to drop your main pack and take the bare minimum. While I’m a trusting soul I always take my wallet and passport (if I have one) along with the essentials such as snacks, small water bottle, my podcasting recorder, phone, GPS, personal locator beacon and some essential gear to cater for adverse weather. This 18 litre pack is a good size and easily managed to take all of the above gear along with my wife’s raingear and lightweight puffy jacket as well.
As an ultra lightweight pack there is no waist strap and I found that I didn’t need it. The pack was comfortable to wear and easily moulded to my back. The shoulder straps are lightweight mesh and have an adjustment strap on them to allow you to adjust the pack to suit your frame.
The pack comes with its own stuff sack built into its construction and packs down to a very impressive 11 cm x 11 cm x 5 cm which disappears into your main pack. I purchased the orange pack at that time which seems to be hard to find these days with the teal, lime and black versions as being much more common. The price is reasonable at just under AUD $69.95 and comparable to the similar options available from other suppliers.
Prior to this 2017 trip I had not bothered with an ultra lightweight day pack but for the sake of 150 grams I am sold on this pack. It now forms part of my long distance gear kit when I know that I will be resupplying in towns and need to go shopping and I now regularly use this pack as part of my long distance hiking kit. It’s also a great little pack for when you are carrying the bare minimum. My pack is now 9 years old and is still going strong.
Best Uses
- Instant daypack that weights almost nothing for when you don’t want to lug your full pack around
