Good In The Arctic!

Shoulder season trips always leave me on the fence about whether to bring a summer weight bag or something warmer. With this new bag, i had an between winter and summer bag. . . and I'm so glad I brought it a 20-day trip to the Arctic Coast during what's proving to be a late spring melt out. . the bag was perfect as overnight temperatures were consistently in the 30s. while my summer weight bag technically can handle, that I sure enjoyed being cozy and toasty!

Awesome Sleeping Bag

Weight and functionality are hard to beat. Keeps me warm. Other down full mummy sleeping bags lack the ability to open up fully like this one, and also have the arm holes. I am a side sleeper and this worked well for me

Best Sleeping Bag

The sleeping bag is warm and super comfy. I ordered the long one because I wanted a little more room. I measure 5’9 and weight 170lb. A plus from this bag is that it’s super lite and compresses to a very small size. I can’t wait to see how it holds up this fire season.

Spark Pro Down Sleeping System

Over the past month and a half I have had multiple backpacking/ hunting trips to familiarize myself with the Spark Pro 15 degree bag. My previous bag was the standard issue Marine Corps sleeping system that weights in just under 4 pounds. I would wake up at night when my feet freezing in mild temperatures. The Spark Down Pro 15 degree bag cut half the weight and no more cold feet. I especially like the zip open footbox and the long side zipper. During cooler nights (40 - 50), I have the bag completely open like a quilt and for the colder nights, I zip it up like the mummy style it was designed for. I couldn’t be more pleased.

Doubles As A Tunic

Love this bag, packs so well and is so lightweight, but my favorite feature is the ability to unzip at the feet and snap over the shoulders to wear it as a tunic! I can get out of my tent to make coffee in the morning by just walking out - in my bag?!?! Amazing. Game Changer.

Fantastic Sleeping Bag

Packs down super small and is exceptionally light weight. I love the modular zippers as it allows me to use the bag in many temperatures. The included storage sack is a nice touch as well so I don't have to keep the bag in its stuff sack giving the down a longer lifespan.

Excellent Sleeping Bag

I used it down in the single digits and was beyond toasty. Packs up very small for what it is, I absolutely love it. The material they use on the outside has the best feel of any sleeping bag I’ve ever had.

Love It

I love Sea to Summit. Their designs are well thought-out, practical, and durable. The Spark Pro down sleeping bag is no exception. It is lightweight, the loft is impressive, and its features are what I've been looking for.

This Bag Is Perfect.

Warm and fluffy, really like being able to open both sides for the arms and really enjoy being able to open the foot box. Bag packs down super small for the size and warmth.

Better Than Expected

This 15 degree, Spark Pro Down sleeping bag, performed extremely well at 27 to 30 degree temperatures and I needed no other accessories to stay worm and comfortable. (Primitive camping for a week) I'm 6'0" tall and the "long" bag was the perfect size for me. It truly exceeded my expectations and I would buy it again. Buy once, cry once but well worth the purchase. -JR

Impressive Bag!

Super lightweight, feels great against your skin, mummy shape, but not too restrictive, quality workmanship, stuffs down super small when using compression straps. The feature to "wear" the bag with your arms and feet out are especially useful on a chilly night or morning! I have not had it long, but I would definitely recommend it so far.

Best Sleeping Bag I’ve Ever Owned

Packs down very small and all the different zippers / venting options makes this bag extremely versatile, absolutely love the fact it can fully unzip into a cozy down blanket.

Great Sleeping Bag

I really like that I can open the foot box when it’s warm out. This allows me to sleep more comfortably in a wider range of temperatures
