Sea to Summit Ultra-Sil Nano 18L Daypack Review

The Sea to Summit Ultra-Sil Nano 18L Daypack is one of those unique products that most hikers haven’t considered but should. As far as a packable daypack goes this is one of the smallest and lightest daypacks available on the market. In fact this pack is so tiny that its storage sack packs down to the size of an egg and only weighs 30 grams.

Now while I don’t carry this on every hike it is something that gets used on a regular basis for two main purposes. First if I’m going on a short hike and just need somewhere to put a few basics like my keys, wallet, water bottle and snacks this little pack is ideal. The main reason I use this pack is when I’m doing long distance hikes. In this instance I will use a little foldable daypack as my carry on baggage for the plane trip and once I start the hike, it becomes my shopping pack in towns when I need to resupply.

Construction wise the Sea to Summit Ultra-Sil Nano 18L Daypack is made of an ultralight 15 Denier siliconised water resistant nylon fabric and is about as simple as it gets. It has a single zip at the top that opens into a single 18 litre pouch. There are two lightweight but non adjustable shoulder straps and like other packs of this type, no waist belt. Given this pack is really designed for a lightweight load a waist belt and padded shoulder straps aren’t really necessary.

On the downside, this pack isn’t meant to be used as a full on day pack. Having said that this pack is supposed to be able to carry 20 kg and while construction wise I’m sure it would cope, that weight would really cut into your shoulders. Personally I think it’s best suited to around a 5-7 kg load, possibly more if you are carrying the shopping home. The other potential negative is that this pack is so tiny there is the potential to lose it either within your pack or altogether if you aren’t paying attention. First world problem I know but store the pack along with all you other tiny items in a safe place. Price wise at just on $50.00 AUD this pack also isn’t cheap.

So is it worth it? For me the answer is yes. The last thing I want to do on a long distance hike is to carry a food shop with my full sized hiking pack and if I’m flying, I still need a travel pack so this is a great option. For the sake of 30 grams you won’t notice the impact.

We Like

  • 30 grams is about as light as it gets in a packable 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
  • When packed this daypack is about the size of an egg
  • Durable water resistant material
  • One size fits all means 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 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 you go bush bashing
  • Being so tiny you need to be careful not to lose it
  • Not cheap but other packs in this category are also similarly priced

Best Uses

  • Instant daypack that weighs almost nothing for when you don’t want to lug your full pack around. Drop your main pack somewhere safe and take the essentials. Also great for doing your shopping
