Why We Like The Sea To Summit Spark Pro Sleeping Bag
The Sea To Summit Spark Pro Sleeping Bag takes lightweight warmth to the next level, cutting weight from our back and packing down small for our pack. The incredible 950-fill down is light and lofty, trapping heat close to our bodies for chilly spring and fall camping trips. The Free Flow zip system makes the bag exceptionally versatile, offering a quarter-length zipper at the top and a zippered footbox at the bottom for easily customizable ventilation for warm-weather trips through the summer months. The hydrophobic Ultra Dry Down treatment and DWR coating on the hood and footbox ensure that the insulating down stays lofty in damp conditions, ensuring we have warm, cozy nights no matter the conditions.

Great Sleeping Bag
[This review was collected as part of a promotion.] 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

Perfect kit addition
[This review was collected as part of a promotion.] This liner is always with me, if I am not using to stay extra toasty in my bag, I use it as a pad sheet for sleeping on during the hot desert nights. Absolute must have for any serious outdoors person

Sea to summit Spark Down zero degree sleeping bag
[This review was collected as part of a promotion.] Best purchase ever! I bought this for the COLD fall nights backpacking in Glacier Park, and it did not disappoint. Keeps me toasty warm. I love the light weight, and it packs down fairly small. The baffles and extra down in the hood are great touches. Would 100 percent recommend this sleeping bag.

so soft and warm
[This review was collected as part of a promotion.] I haven't taken this bag out yet but I've tested it at home and it's feather-light and so comfortable. We're going backpacking this weekend and I'll report back.

High Quality, Lightweight
[This review was collected as part of a promotion.] This sleeping bag has just about every feature you could wish for. You can unzip the arm area, the foot area, and fully unzip it to use as a blanket. You can even zip two bags together! It cinches up around the head and neck area to keep in maximum warmth. It’s also filled with goose down, allowing it to be both breathable and incredibly warm. What I’m still blown away by is the weight- it comes it at under 2 lbs and compresses down into a very small pack. This is perfect for overnight hikes where every ounce matters. I’m so excited to bring this along for cold weather camping!

Best sleeping bag ever!
[This review was collected as part of a promotion.] Love this sleeping bag!!! It is probably the most comfortable, well insulated sleeping bag I've ever owned! I've attached pictures of it unrolled with no one in it, and a pic of me inside with room to spare! The hood attachment part is probably the best part in my opinion. No more cold heads when camping! Rolling it back up for storage was also super easy, which is always a plus. I would definitely recommend this to anyone camping, especially in colder climates!

It packs down incredibly small, making it a great choice for long treks where every ounce counts. This high-performance bag is also comfortable and toasty, with a roomy ergonomic mummy shape that offers a good balance of warmth and wiggle room. This is an excellent choice for serious backpackers.

Very warm!
[This review was collected as part of a promotion.] Very warm and soft material. I love that their are zippers on the side to vent but also you can take your arms out. Folds up small and has a carrying case so it doesn't take up a lot of space.
