Frequently Asked questions

Aren't most backpacks waterproof without a cover?

No. Water will enter through seams and zippers (especially in really wet parts of the world)

Why choose the Ultra-Sil Pack Cover over the Nylon version?

The Ultra-Sil Pack cover is slightly lighter and has a smaller packed volume - it is more suitable for weight-conscious backpackers

Will a pack cover make my pack completely waterproof?

In most cases, waterproof enough - wind-driven rain can still enter through the space between your back and the harness
