Special order items take longer to ship

We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

Rated 5 out of 5 by from Definitely Keeps you WARM! I used this as a bag liner when we camped in Yellowstone. Temps got down to 30F degrees at night, and my 40F bag needed help. This liner was super small to pack and yet it really added what was needed for those cold nights. Good option to bring with that doesn't take up much room.

Rated 4 out of 5 by from Reactor Extreme Liner Bought it for my son that is using it for the first time camping this weekend, hence the only 4 star rating. Seems well made and stitched and appears it should work as advertised. Will update this review after he returns.

Highly recommend this liner for anyone who wants a multi-season sleep system or just wants to sleep warmer. Wish the liner was a bit lighter but the extra weight is worth it!

What is the packed size of this one? I notice for the others a packed size is listed but I didn't see one for this one...

Asked by: Sonya
Hello Sonya, This can fit into a stuff sack size of 6.5 x 4.5 in. Hopefully this helps!

How does this compare to the fleece liner also from S2S? Most specifically, pack size and temperature. Thanks.

Asked by: Tony
Hey Tony, great question! The Reactor Extreme liner packs down to about the size of a solo cup and is rated for 25 degrees Fahrenheit. The Reactor Fleece on the other hand, packs down to the size of a standard Nalgene bottle, and is good down to 32 degrees Fahrenheit. I hope this helps!
