The Ultra-Sil Pack Cover from Sea to Summit for ever ends the debate about whether you can afford the extra weight of a pack cover - the medium size weighs less than 4 ounces and packs into a tiny stuff sack.

• Made of 30D Diamond Ripstop silicone impregnated Cordura, so its waterproof finish cant peel or wear off over time
• Siliconized Cordura is about one third the weight of traditional coated nylon
• This pack cover uses a œno seam construction for complete waterproofness
• Has a mid-back keeper strap that helps secure it to the pack and keep the sides from catching wind (except size XS)
• Comes packaged in its own mini siliconized nylon stuff sack that remains attached to the cover so it cant get lost
• Comes in four sizes to fit daypacks up to large backpacks
• Comes in assorted colors only; sorry, specific color requests cannot be accommodated
