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.

Can the Retro-Fit Wheels...?

  • Fit in a sea kayak hatch? The wheels measure 9.85 inches / 25cm in diameter. They should just fit into a 10” hatch.

  • Be used on soft sand? Possibly not. On very fine-grain sand the rim of the wheel will sink and the spokes will become clogged with sand.

  • Be used for kayak carts made by other manufacturers? Probably not. To determine if these wheels will fit your cart, measure the external diameter of the axle: “25mm” or “35mm” refers to the interior diameter of the wheel hub.
