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.

DWR tech

Durable Water Repellent
DWR (Durable Water Repellent) is a coating that is applied to fabrics which makes them water-resistant, or hydrophobic. A DWR finish doesn't interfere with breathability, which makes it perfect for adverse conditions in the backcountry.

Product Reviews
Rated 5 out of 5 by from Excellent bag, lightweight and compresses well The stuff bag that came with the mummy bag is quite useless as it requires significant effort to put the mummy bag in. The bag needs to be slightly bigger. I recommend purchasing a compression sack with this bag.

Rated 5 out of 5 by from Great bag! [This review was collected as part of a promotion.] I have used this on campground nights and mountain nights in the backcountry and it has continued to serve me well. I am ALWAYS cold camping but this bag keeps me warm, but not too warm on chilly nights. light enough for trekking

Rated 4 out of 5 by from Toasty Bag with Long Life [This review was collected as part of a promotion.] I've had this bag for over 5 years, and it still is toasty warm. I work in the outdoor industry, and it can be difficult to find a bag that retains it's warmth over time. I will bring this bag for temperatures as low as 28 F. Anything lower than 28 stretches the warmth capabilities of this bag. My freezing toes are always toasty in this toe box, and if stored properly, the down remains even around my torso. One comment is that the hood bungee constantly needs to be readjusted and comes loose from the seaming. One of the better quality bags for the price.

Rated 5 out of 5 by from Happy Camper [This review was collected as part of a promotion.] I bought this on a whim as I needed a quick sleeping bag and I'm so happy with this item. It's been a veristal sleeping bag in all conditions. You can tell it's well built and has very little dead air space if fitted correctly. I'd definitely buy again <3

Rated 5 out of 5 by from Helium in the Wind River Range [This review was collected as part of a promotion.] The helium bag was warm and comfortable. Some bags are too tight and constricting to achieve light weight. Not the helium. Construction is impeccable. Highly recommended.

Rated 5 out of 5 by from The do it all bag [This review was collected as part of a promotion.] I’ve had this bag for over a year now and I’ve taken it everywhere. Spent cold nights sleeping on glaciers in Alaska, backpacking in the Tetons and in the alpine of Colorado. 15° is a perfect sweet spot all around and the 800 fill keeps you light and warm. Would definitely recommend this to anyone looking for a good do it all bag!
Date published: 2022-07-27
Rated 5 out of 5 by from Good Value [This review was collected as part of a promotion.] This bag is light, warm and compact when packed. Perfect combo!
Date published: 2022-07-27
Rated 5 out of 5 by from The perfect Bag! [This review was collected as part of a promotion.] This is the one. Mine is comfortable to 20 degrees or less.

Does this version of the Helium 15 have the water resistant down? (Down Defender)? Thanks!

Asked by: Surfah
Hey there! Thanks for reaching out to us. Did I tell you about my granddad? See, one night he had a nightmare. He was so scared, he chewed his pillow to bits. Bits. In the morning, I asked him how he was feeling. He said 'Oh, not bad. A little down in the mouth'. (Mic........(wait for it)..........DROP). Any-who, this bag does in fact have Down Defender to help improve water-resistance in wet conditions. Hope this helps you out! Hugsies.
