Ultra-Sil Pack Covers

G'day Saskia,

Unfortunately, we're not overly familiar with the Gregory Deva 70 so it's hard to say exactly which pack cover will be best. I've had a quick look at this pack online and they're listed as having a rain cover, which I would assume will be similar to the Sea to Summit pack covers. I would personally steer toward the standard cover as they tend to be a little more durable over time.

G'day Tam,

Thanks for your enquiry. I have had a chat with a few experts regarding your question as there are a couple of variables to consider. As we don't stock the One Planet brand, I was unable to physically try each size of the Sea to Summit Ultra-Sil Pack Covers but I've spoken with a rep at One Planet who was able to provide the dimensions of the 70L pack and after discussing the question with our travel experts in store, we think it's best to purchase the Large size to be safe. The pack covers come with drawstrings so you'll be able to tighten the cover if you find it's sagging a bit but we feel if your pack is close to full plus items in the front pouch of the pack, you're best to go with the large. I hope this helps. 

G'day Lloyd,

On the Sea to Summit Ultra-Sil Pack Covers, there are no attachments that you can use to hook the stuff sack to your Molle system. The only thing you might be able to try and use is the drawstring but I'm not sure it would work all that well for you. 

G'day Dale,

When buying a Sea to Summit Ultra-Sil Pack Cover, you can choose whichever colour you'd like after selecting the size. That way you can guarantee you'll get the colour you want. 

G'day Michelle,

The Sea to Summit Ultra-Sil Pack Cover is a waterproof cover that will protect your bag against the rain. It doesn't, however, provide a watertight seal around the bag.
