Sea To Summit Ultra-Sil Day Pack - 20L

Small enough to be on your keyring the Ultra-Sil Daypack is always there when you need it.

This bag is great as a summit pack, for carrying groceries, or as an extra traveling tote. When packed into the attached mini stuff sack, it’s easy to take anywhere. It is strong, yet compact and light; a must have for everyone from backpackers to students and mums.

Review: Great lightweight packable simple backpack. Ideal for multy purposes - It's great for when you're travelling and need a day pack, for music festivals, or day trips. Strong enough material, super lightweight, and very small packed size - packs down into a tiny ball you can fit in a pocket or clip to your belt loop. Focus on lightweight & small packed size means that luxuries such as padding & thick straps are sacrificed. However, it's perfect for its use case and you can fit a surprising amount into it without much of a struggle. I'd definitely buy it again!

Cordura fabric: Constructed using high tenacity fibre technologies, weight for weight, CORDURA® fabrics are exceptionally durable. Fact is, no matter the application, their fabrics are “best-in-class.” But more importantly, they have to pass their own stringent test criteria before they can earn the CORDURA® brand name.

30D Ultra-Sil®: 30D Ultra-Sil® is a 30 denier 240T Nylon made from a high-tenacity Cordura® brand yarn. High-tenacity nylon is stronger and more abrasion resistant than standard nylon fibres. We use two different versions of 30D Ultra-Sil®: a Sil/PU and a Sil/Sil version depending upon its purpose and use.

  • Sil/Sil: 30D high-tenacity Nylon with silicone impregnated on both faces. Silcone impregnation works really well with lightweight fabrics as it improves fabric tear strength, abrasion resistance and packability. Siliconised fabric has a measure of self-healing when punctured. This fabric has a water resistance of 600mm and is used where a product needs to be water-shedding and water resistant but not necessarily waterproof. We use Sil/Sil for products where ultralight weight and strength are most important, such as our Ultra-Sil® Day pack, Duffle, Shopping bag and Sling Bag.
  • Sil/PU: 30D high-tenacity Nylon with Silicone impregnated on the outer face and a polyurethane (PU) coating on the inside. It has a water resistance of over 2,000mm. The Silicone outer works really well for water shedding and to create a slippery surface for easy packing. The PU coating on the inside improves the waterhead rating and allows seam sealing tape to bond. We use Sil/PU in products that need to be waterproof, such as our Ultra-Sil® dry day pack, Ultra-Sil® dry sacks, Ultra-Sil® pack liners and many other products.
