THERMOLITE

THERMOLITE
THERMOLITE is a high loft synthetic insulation. It features hollow-core and solid core fibers, which combine to provide lightweight warmth that stands up to constant use. When placed inside the Air Sprung Cells of Sea to Summit sleeping pads, it prevents heat loss from your body to the ground.

15D ULTRA SIL

15D ULTRA-Sil
15D ULTRA-Sil is a lightweight waterproof fabric. Built to withstand the storm, but with less weight and a smaller packed size. The fabric is a 15 Denier Sil/PU coated nylon, rated to 12,000mm. This way you and your gear stays dry.

Sea to Summit ULTRA-DRY Down

Sea to Summit ULTRA-DRY Down
ULTRA-DRY Down is a treated insulator for Sea to Summit sleeping bags. ULTRA-DRY treated down repels moisture, so when your environment is damp, your gear stands a much better chance. The down will retain its loft, dry faster and is even anti-bacterial and anti-microbial, improving their life span. When conditions are bad, your bag doesn't have to be.

Product Reviews

Rated 5 out of 5 by from Obsessed! [This review was collected as part of a promotion.] This sleeping bag is truly my holy grail! It’s comfortable, versatile, warm, and beautiful! I’m a side sleeper who tosses and turns a lot and this bag didn’t make me feel constricted at all. My feet also tend to get warm so I really liked the zipper just for the end of the bag. Highly recommend!

Rated 5 out of 5 by from Couldn't Love More I'm a HUGE fan of this sleeping bag - as someone who spent years shivering through the night in old/inefficient sleeping bags, the women's specific body mapping of this bag made all the difference! The length/shape of the bag means no "dead space" (where air could stay cold), which is impressive given its not a mummy bag - there is room to sprawl a bit more. While there is extra warmth in the toes, and extra warmth around the chest (with keeps cold air from getting in), simultaneously this bag has all of the zippers you could need to ventilate on warmer summer nights (bottom of bag, both sides to make it more duvet style). The quality of the down/material itself is really nice - super soft and lofty. The bag still bags down incredibly small and lightweight as needed. Genuinely don't have any critiques of this bag and would highly recommend. For reference - I'm 5'4'', and my toes don't touch the bottom of this bag but I can stay plenty warm. 125lbs, and plenty of room to wear several layers if wanted and still be able to move around.

Rated 5 out of 5 by from 10/10 sleeping bag [This review was collected as part of a promotion.] This is the best purchase I’ve made. I go backpacking often and having a quality sleeping bag makes a huge difference for comfort and light weight carrying. I would recommend this sleeping bag to anyone.

Rated 4 out of 5 by from I got my sleeping bag, [This review was collected as part of a promotion.] I got my sleeping bag, and I’m super excited to try it. I love that it comes with both a compression sack and a storage bag. I wish the inner pocket for the phone was a little larger as my phone doesn’t quite fit.

Rated 5 out of 5 by from Money Well *Slept* ;) [This review was collected as part of a promotion.] This is hands down THE best sleeping bag I've ever owned! Well worth the investment!! I am obsessed with the color! & Its performance is immaculate! The zippers are easy to zip up & down without worry of snagging. & Even when the temps dropped during the night on my last camping trip, this fluffy bag kept me comfy & cozy all night without needing extra layers or a heater in my tent! I love my Sea to Summit sleeping system!!! (I only wish my new Aeros Down Pillows had arrived in time for this last trip!)

Rated 5 out of 5 by from Best Sleeping Bag! Buy it! I've had this sleeping bag for over 3 years (still going strong) and its been everywhere with me! From car camping trips to multi-day treks in all different climates, it will keep you comfy with all the different options. I thought I would want the lighter weight and more compact Flame Sleeping Bay by sea to summit, (and I am sure I would like it) however I am so glad I got the Altitude Bag instead. I love all of the options and configurations (mostly being able to unzip the foot box and stick my feet out when I want. To me It is worth the extra weight ! The bag keeps me warm when I need it and I can change the set up so I can stay cool if I need to as well. If you are considering this you will not regret buying it!

Rated 5 out of 5 by from The Best Love the roominess to roll around, the versatility of the zippers for hot or cold nights, and being able to zip it together with my boyfriend's bag.
Date published: 2022-11-16
Rated 5 out of 5 by from Wonderfully made but not for fluffy people I really like that it zips on both sides. It is super soft, well made, and packs down small. However, it isn't for robust people. I am 5'4" and weigh 190lbs. I had one heck of a time getting it zipped up. Can I still use it? Absolutely! But it isn't comfortable zipped all the way up. I'll have to use it partially unzipped on both sides. I still give it 5 stars because it is an awesome bag and it isn't their fault that I like tacos and beer.

Would it be appropriate to consider this bag as a 5 to 10 degree men’s bag for a shorter (5’6”) male? Is the fabric same as men’s ascent version. Is the thermo layer on the underneath or top portion of the foot box?

Asked by: Rlopez2106
Hi Rlopez2106, thanks for the question! The insulation and shell on this bag is comparable to that in the Ascent, the only major difference here is the addition of the Thermolite Insulation on the underside of the footbox. If you fit comfortably in this bag, you may be able to see those lower temps. I hope this helps!

Is the temperature rating -15°F or 15°F?  The name is “15F” so I wanted to double check. 

Asked by: amarisa
Hey there amarisa, thanks for the question! The temperature rating on this bag is +15°F, with a full comfort range from 15°-60°F. I hope this helps!
