Great raincover

  • Familiarity: I've used it several times

I've used this cover on several backpacking trips and it always keeps my gear totally dry, very easy to use and folds up into its own little pouch.

Keeps your gear dry! Seams.....

  • Familiarity: I've used it several times

I have only been caught in the rain and needed this cover 3 times this year since I bought it.

So far it has held out even torrential rain when I have needed it.

So far I have not had problems with the seams but they do not look the best, and I am a bit of a seam stickler so I have to knock of two stars because I highly doubt this is going to last as long as my osprey rain cover.

Keeps bag dry, but breaks easy

  • Familiarity: I've used it several times

I used this in a few rainstorms on my backpacking trip. My stuff stayed dry, but the plastic on the drawstring broke after just a few uses. I would spend a little extra money to buy a better made product.

What size would you suggest for a triple aught design fast pack litespeed?

Responded on

Hi Kaleb,
Looks like that bag is a 47.5 liter, so I would recommend you go with the size Small!

Seems good

  • Familiarity: I've used it once or twice and have initial impressions

I haven't field tested this yet and won't for some time, but I thought I'de share my thoughts on the sizing, as that seems to be one of the biggest ambiguities prior to purchase.
I have a 65-70 litre pack and ordered a Large because I wanted to have some extra room available for things tied externally. Large was a good choice. There is ample room for a few items to hang on the outside of the pack, yet not so much that the tarp is obnoxiously big when there is nothing attached to the pack or when it is only three-quarters full.
Overall construction seems good- taped seems, feels durable, nice stash pouch.

Good Bag, Bad Clip

  • Familiarity: I've used it several times

I use this bag to protect my backpack during extremely heavy east texas rain storms. The bag keeps my backpack, containing school books and a laptop, completely dry. The only complaint I have is that the clip used to cinch down the bag, broke the first time I put any strain on it. I now just make a slip knot to hold the clip, and it works fine. I wish the clip would have lasted longer, but again, the slip knot works.

Would the Extra Small fit a Maxpedition Lunada?

Responded on

Judging from their website it looks the fit should be no problem.

Responded on

the Lunada has an aprox. overall volume of 390 cubic inches. the xs is designed to fit packs at least 4 times that size. yes this rain cover would fit over it, but you'll end up with lots of extra material, and not a good fit.

So dry

  • Familiarity: I've put it through the wringer

This cover worked great was caught in a flash rain storm and the cover was easy to put on and kept my pack dry ?

Backpack cover

  • Gender: Female
  • Familiarity: I've put it through the wringer

Didn't work that well. Fell off as I was hiking a hard trail with it. Straps (of course) got soaked during normal wear. The part that was covered was well protected and it folds up compactly. The material is sufficiently rugged. But I will try a poncho next.

Do these fit well on a pack that has nothing sticking out above the shoulder straps? I'm running a 5.11 Tactical Rush 24 and I'm concerned the cover won't stay on.

Responded on

define well. the elastic will hold it on to the bag, but it can be pulled off and the shoulder straps will cause there to be a small gap between your back and the rain cover where rain can get in. my wife's 5.11 tactical backpack has some velcro on top, so i imagine you could modify a raincover with some stick on velcro and engineer a better system.

Good pack cover for the price

This is a good basic pack cover to keep your gear dry. The drawcord makes it quick and easy to cover and uncover your backpack.

I have two packs, both 30L, which seem to...

I have two packs, both 30L, which seem to be inbetween Small and Xsmall. The dimensions are 24" x 12" x 6" and 21 x 11 x 6 inches. Any suggestion on which size to go with. I won't be lashing any equipment to the exterior of either bag. I would prefer a snug fit without having to cinch drawstrings, I'm just paranoid that Xsmall will be too small. thanks in advance. Also, the dimensions and capacity listed here are not the same as those listed on the manufacturer's website.

Responded on

I would recommend going with the Small. The XS was designed for bookbags and 30L is a touch larger than that.

Hope this helps!

I'm contemplating buying this for a school backpack in a rainy climate. The knapsack in question seems to be roughly 20x14x12...will a Large cover be unhelpfully loose on a stuffed knapsack, or will the Small/Medium somehow cover enough to keep all the papers/laptop dry?

Is this specifically designed for Mountainsmith...

Is this specifically designed for Mountainsmith packs, or will it work with any brand, as long as I buy the corresponding size?

way too small


i have a vaude 45 + 10 Liter pack, and i bought small (which is supposed to fit up to a 58 liter pack), but i had a hard time putting the rain cover over my pack when the pack was NOT that full (closer to 45 liters of volume at the time).

Otherwise, the cover looks good.. but it doesn't fit. ORDER A SIZE UP!!! (or two..)

Not Sure

This product is okay. I didn't want something that only covers the bag but I wanted a cover that actually covers all the bag. The bag doesn't get wet in the rain, only the straps and it does its job. I think there can be better covers than this.

excellent product

even when i was a little anoing because the cover itsn't totally closed i try on my bag pack (i use it when i ride a bike under the rain) and my surprise was that the bag didn´t get wet at all (only the strips tha obvioustly stay out the cover) so I recomment this product.
