A Brief History of Sea to Summit Dry Bags

      Our Dry Sacks are not designed for water storage; the interior coating is not food grade. If you need to carry water for a short distance, the Folding Bucket or even the Kitchen Sink is a much better option. And for longer term storage, the Pack Tap is the way to go.

  1. So which of these bags works best in cold weather – for not being stiff or developing cracks after being flexed repeatedly?

      Thanks for contacting us about use of dry bags and X-Pots in cold weather. Sorry for the delay in replying – we’ve had some issues with messages not being forwarded from the blog.

      As far as the dry bags are concerned, you shouldn’t have any issues down to very cold temperatures below 0°F / -20°C. Unlike some other dry bags on the market which use basic urethane laminates, the welded bags (Stopper and Hydraulic) are made of Thermoplastic Urethane which would still be pliable at these temperatures. The sewn fabric dry bags (Lightweight Dry Sacks, eVac Dry sacks, Big River Dry Bags) will still be pliable at even colder temperatures, although care should be taken with the polypropylene stiffener built in to the roll-top closure of this type of bag.

      As to the X-Pots, the silicone rubber can be collapsed and expanded at temperatures below 30°F / 0°C. The silicone rubber may become stiff at temperatures around 20°F / -7°C, so we would advise cautious use in winter / mountaineering conditions (or rely on a more common alloy or titanium pot).

      If you’d like more details on either of these topics, shoot us an email at marketing@seatosummit.com and put ‘Cold Weather Performance’ in the subject line

      Cheers
