SITKA Kelvin Aerolite 30 Sleeping Bag Review

By Brodie SwisherJuly 12, 2021

Planning a hunting trip with a tent or truck as your base camp this season? If so, you might want to check out the all-new SITKA Gear Kelvin Aerolite 30 sleeping bag.

It’s the answer to the demand by hunters for a bag built specifically for hunting camp. Check it out in the video below…

The Final Layer

SITKA has been designing clothing systems to protect in extreme conditions for many years. They’ve got the program figured out when it comes to gear that performs well for hunters on the move, while maintaining warmth and comfort at the same time. 

However, for 2021 SITKA turned their attention towards delivering the final layer to complete their mobile warmth layering system. That final layer is the Aerolite 30 sleeping bag. It was designed to be way more than just a sleeping bag. It was built to be an extension of your layering system.

How it Performs

As the name implies, the Aerolite 30 has a comfort rating of 30 degrees. And while that may not seem like enough horsepower to handle extreme cold temperatures, keep in mind the bag is built as an extension of the SITKA clothing system. 

As the temperatures dip below freezing, you simply stack on additional layers under your bag to extend the comfort rating. By layering up  within the  bag, SITKA has developed a system to handle temperatures to 20 degrees, and even 10 degrees. 

The bag is built with lightweight, synthetic insulation designed to maintain warmth, even when wet. It has a durable water repellent finish that prevents the face fabric from wetting out.

A Different Design

“Building a system is not something you do as much as it’s a way you think,” says John Barklow, SITKA Big Game Product Manager. “We took experience and insights designing clothing systems and applied that knowledge to the sleeping bag, turning something you typically use just for sleep into a multifunctional tool for backcountry use.”

With zippered arm holes, the bag features a jacket-like design that allows you to stay functional while staying within the bag.

The single greatest feature of this sleeping bag is the armhole access.

Zipper pulls on the inside and out allow you to easily get in and out of the arm holes to use your hands, work around camp, pour coffee, take a leak, shoot an intruder bear, etc. It’s the single greatest feature of this new sleeping bag.

Another slick feature of the bag is a second zipper that allows you to pull your feet from the footbox and walk around camp without having to come out of your sleeping bag. 

This is super handy for when you need to move about, but aren’t ready to come completely out of your bag. It’s also really handy for when you want to add another layer to knock off the wind and chill while glassing in the wide open.

The Aerolite 30 pulls double duty as another layer to knock off the wind and chill while hanging out around camp, or glassing in the wide open.

A stowed hook at the bottom of the bag connects the footbox to a midlength interior loop which shortens the bag to ease in mobility. It’s a really slick design that allows you to maintain warmth, day or night, without having to come out of the bag.

Hang the bottom of the bag by the attached clip and strap to give you freedom of mobility to walk about while staying inside the bag.

Like the rest of the SITKA lineup, you get what you pay for. If you’re looking for a cheap sleeping bag, this is not it. However, the Aerolite 30 is competitively priced among other high end sleeping bags on the market, ringing up at $399.
