Sleeping Bag Temperature Ratings Explained

The EN Rating scale is a scientific test to determine the warmth of a sleeping bag. The test produces a Lower rating (for male sleepers) and a Comfort rating (for female sleepers). Both are listed in the features table on the product page.

A unisex sleeping bag with a Lower limit of 23ºF means a man should be comfortable down to air temperatures of 23ºF. The same bag will also have a Comfort limit, in the realm of 32°F, so a woman would be comfortable down to an air temperature of 32ºF. These ratings require a sleeping mat with an R-Value appropriate for expected ground temperatures – without this, the sleeping bag itself is unlikely to keep the sleeper warm enough.

A variety of factors impact sleeping bag warmth - the above temperatures are merely guidelines, not guarantees. It’s important to think of a sleeping bag, an appropriately insulating sleeping pad and a liner as a sleep system. For example - if you plan on sleeping in nighttime air temperatures of 27ºF / -3°C, choose a bag with a gender-appropriate rating of 23°F / -5°C, plus a sleeping mat with an R-Value of 2.5 to 3, and consider a Reactor thermal liner.

Description

The Stopper™ Dry Bag is a fully welded dry bag made from 210D nylon fabric with TPU lamination on the outer face and RF welding for optimum durability. With a nice clean profile and oval base for easy packing, the Stopper™ dry bags are perfect for canoeing, kayaking, rafting, general boating, SUP boarding and any activity where water shedding and abrasion resistance is paramount. Uses a reliable TPU Roll-top, non-wicking closure, and features Field Repair Buckles which can be replaced in seconds with a Philips screwdriver.

ARE stopper DRY BAGS...?

  • Suitable for paddle sports? Absolutely. The tough TPU laminate is perfectly suited to watersports use. Just apply reasonable caution in sharp and abrasive environments.

  • Waterproof? The fabric is more than adequately waterproof (10,000 mm hydrostatic head) – just avoid submersion, as water can seep through the roll-top closure of any dry bag.

  • Suitable for motorcycling? Yes and no. Stoppers pack down small when not in use, and shed water reliably when called into duty – but the Big River Dry Bag has lash points for securing to a rack.

Technical Features

210D Stopper Fabric

The Stopper fabric starts with a 210 Denier Nylon carrier fabric to which a Thermoplastic Urethane (TPU) layer is laminated. This creates a fabric that is extremely waterproof while remaining soft and pliable – so you can stow a Stopper Dry Bag in tight spaces.  It has exceptional abrasion and puncture resistance. The TPU laminate construction also allows for all the seams to be Radio Frequency (RF) welded.

Thermoplastic Urethane (TPU)

Thermoplastic Urethane (TPU) is a PVC-free material used in a number of functional areas within Sea to Summit products:

 

  1. As an airproof barrier in our Air-Sprung Cell™ and Self-Inflating mats. Here it is used in a liquid-extruded format – the TPU bonds to the face fabric for the highest possible level of reliability.
  2. As a waterproof barrier in our Accessory Guide Cases and Map Cases; and in several models of our Dry Sacks. Here it is used in a film format, where its superior flexibility (even in cold weather) and waterproofness are key.
  3. As a waterproof barrier in the Nylon Folding Bucket. This particular film is also food grade – ideal for water storage.
  4. As a transparent window in View Dry Sacks and Travelling Light products – allowing you (and TSA inspectors) to see the contents.

PVC Free

This product is free of any Polyvinyl Chloride (PVC). This means that the production process is significantly more environmentally friendly, and the disposal of the product at the end of its life will also not burden the environment. With advances in modern polymers, it also means there's no reduction in performance.
