Sea To Summit Ultra-Sil Pack Cover -

The Sea to Summit Pack Cover Sn240 forever ends the debate about whether you can afford the extra weight of a pack cover especially considering the medium size weighs only 4 ounces and packs into a tiny stuff sack.
Made of 30D Diamond Ripstop silicone impregnated Cordura®, this cover's waterproof finish can’t peel or wear off over time.
Siliconized Cordura is about one third the weight of traditional coated nylon. This pack cover uses a “no seam” construction for complete waterproofness, and has a mid-back keeper strap that helps secure it to the pack and keep the sides from catching wind. It comes packaged in its own mini siliconized nylon stuff sack that remains attached to the cover so it can’t get lost. This pack cover comes in four sizes to fit daypacks up to large backpacks.

Fit:

  • Comes in four sizes to fit daypacks up to large backpacks
  • Fits packs 1,800-3,000 cu. in. (30-50 liters)

Fabric:

  • Siliconized Cordura® is about one third the weight of traditional coated nylon

When a waterproof pack cover is this light (3 ounces), bringing it along is no hassle at all. It even comes with its own stuff sack.

Tough, lightweight, easy to stow.

Don't usually write reviews, but I was surprised to see just one review for the Ultra-Sil pack fly. Mine has worked great. Primarily purchased for a day-trip from Yosemite Valley Floor to the top of Half Dome last July. WIth the heavy snow last winter the Mist Trial was like walking hiking through a typhoon. My Med Ultra-Sil (Gray color) slipped nicely over my Kelty 44L Redwing pack. Cinch and strap served to hold the cover on securely. For such a light material (Ripstop) it seems very durable. Jamming against jagged rock on the trailside left rock walls left no marks, and the thing packs so small and weighs so little it never leaves my pack between trips. No problem getting it back in the attached sack between uses for me, BTW. Highly recommended. I'm gettin another for my bigger pack now for a trip to Philmont and up Whitney this Summer with my sons.

Loosey-goosey pack cover

The concept is good: packs need to be protected from rain and they need to be visible for bikers and hikers along roads. Visibility should be a major concern for traffic safety and rescue efforts.The available colors are too dull for the required degree of safety. (I got the orange color, but it is not traffic-cone orange.)

As for rain protection, the overbag seems capable of shedding rain, but the fit is loose and large, so rain might trickle down the wearer's back. I got the Small, but it still seems large for bookbags or small daypacks. I would have appreciated more straps to adjust the rain cover to fit the pack.

Super-light pack cover

These pack covers, made of siliconized cordura nylon, are spectacularly light. An elastic drawstring that runs around the edge of the cover is useful to tighten the cover so that it fits nicely around the pack. Each cover comes with its own tiny stuff sack.

The extra-small is the standard size to fit most day packs. Packed into its stuff sack it is smaller than my fist and weighs in at a near-negligible 2 oz!

It might take a couple of tries to get the cover back in its miniature stuff sack the first time you try it but with a bit of practice it becomes easier.

Great Protection

Very pleased with this pack cover - Small size worked like a charm with my Kelty Redwing 44 (2650 ci). It's very lightweight, self-contained (cover attached), and easy to deploy. Seems to be very durable for the weight, and well designed. This cover tamed the mist trail in what is probably one of the wettest season in Yosemite on record!

Bomb Diggity pack cover

This is a very tough pack cover,and my third one that I own as well.I use them on all of my backpacks,Sea-to-Summit makes wonderful products,I also use their stuff sacks and mesh sacks,perfectly sized and light weight and at a very affordable price for what they are.

Excellent quality

I use my backpack almost every day. I struggled with how to keep my Laptop dry in pouring rain. The waterproof cover takes no time to deploy, and is removed and packed in a minute. The cover keeps my gear completely dry.

Works For Me

I've read some reviews that this cover tears easily when packs are (carelessly) dropped. It's water resistant nylon - NOT Kevlar. It works as advertised.

As Described

I bought this to protect my camera gear that is enclosed in a water resistant backpack designed for that use. Redundancy.
