Sea to Summit Trek -1C/30F Down Sleeping Bag - Regular

This sleeping bag can keep me warm even in really cool temperatures. I go both tent camping and camper camping (sometimes without heat while doing the latter.) I love the blue color. It’s very appealing to me. However, from the get go the snaps at the top of the sleeping bag broke off. This should never happen on the first use. There also appeared to be no way for me to even sew them back on. Since this is a mummy bag the top is supposed to go up and keep my head warm. I’m an average height and female. I felt that the top didn’t leave enough room to go over my head. When I tried to turn on my side it was quite uncomfortable. The only way to lay is truly on my back the entire night. The sleeping bag allows me to unzip at the bottom for my feet, however, that made me ... MoreThis sleeping bag can keep me warm even in really cool temperatures.

When I tried to turn on my side it was quite uncomfortable. The only way to lay is truly on my back the entire night. The sleeping bag allows me to unzip at the bottom for my feet, however, that made me feet cold so I zipped it back up. The bag is made of down which is warm but that meant several feathers came out immediately. I tried to use the inner zipper at the top once I was in the bag and the zipper was not smooth. While the bag is warm, it is uncomfortable and very poorly made. I won’t be using this again and will go back to my regular sleeping bag for camping.

I love this sleeping bag! I typically go camping more casually, as in not backpacking for multiple days, etc., so keep that in mind when considering my opinion. The sleeping bag is lightweight yet warm. I’m glad it unzips on either side and includes various snaps and loops for increased functionality. I am an average height female of slim stature but I chose to purchase this version instead of the women’s version. I haven’t compared sizes or other specs, but figured the unisex version was a safer and more flexible bet. I picked the 30 degree sleeping bag again for flexibility. I’ll be able to layer within the sleeping bag if I happen to camp in colder weather. I love the vented storage bag (as pictured). Not all sleeping bag storage bags are vented and that’s a big ... MoreI love this sleeping bag!

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!

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 ... MoreI'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.

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.

Good quality sleeping bag

I can't wait to use this camping! This is a very nice quality down sleeping bag. It's comfortable and roomy and is rated to keep you warm down to 15 degrees! The down didn't poke through the fabric and the zippers worked nicely. My only issue is that one of zippers seems to need fixed as noted in one of the pictures. I like that it came with both a storage cube so the down doesn't get deflated in storage but it also has a travel bag for your trips!

Gorgeous color and I love the design and materials

I love the hooded part of the sleeping bag. It’ll be extra warm and comfortable for the head and face. The bottom of the bag has a zipper to let air circulate around the feet. The color of the bag is so vibrant and beautiful. I love the turquoise color. It’s super soft with the down insulation and the outside material is soft to touch. It’s gonna be so fun to use out on camping trips in the future.

In love!

This sleeping bag is a dream! I'm so excited to use it while camping. Its so soft, extremely lightweight and super warm and comfortable. It has durable zippers and closures. Opens from the top, side, AND bottom. Which is great for people like me who don't like their feet enclosed. I love down filled and knew right away I was going to fall in love with this sleeping bag. It even has a closure to tighten up around your enclosed head. Complete protection and warmth!

Top of the line product that wont disappoint

The package quality is next to none- the quality of the sleeping bag feels like a sleeping mat built into the sleeping bag.Also comes with a user manual and a sleeping pouch container to hold the sleeping bag.Using it for last 1 month3 things that stood out1. Feels like I'm sleeping on a could, sleeping bag comes with a comfort padding and not just a bag with cheap/useless materials.2. Quality control is superb, company makes sure products are correct and very attention to detail.3. Overall the retention of heat is appearant and the product holds to its standard

I purchased the Sea to Summit TrekII -8 a few months ago and have been on a 9 day kayak trip and multiple multi-day backpacking trips with it. First off, I loved the shape and idea of this bag and after a long while researching and comparing it to others, bought it! Loved the bag when I received it for these reasons:- love the way it opens to a quilt, this is amazing for warm summer nights- colour and shape of great- seemed well built with a good amount of down (no gaps observed when held up to light)- stuff sack and storage sack are greatAfter using this bag well for the season, it was time to wash it. I have had many down sleeping bags over the years and have always followed the instructions and used the correct products to wash and dry. I am extremely ... MoreI purchased the Sea to Summit TrekII -8 a few months ago and have been on a 9 day kayak trip and multiple multi-day backpacking trips with it.

I have had many down sleeping bags over the years and have always followed the instructions and used the correct products to wash and dry. I am extremely disappointed that after multiple attempts, I cannot get the down to unclump in a number of key areas. This includes around the hood, the draft tube and around the foot box. Like I said, I have tried a number of times to remedy this, especially with tennis balls and even bought a Granger kit with included dryer balls. Nothing has worked. I have taken the bag since then on a multi-day trip where it was only 6 degrees over night and suffered notable cold spots in all of these places. The trip was unfortunately not very enjoyable due to this and I am thinking I will require a new bag going forward.I love Sea to Summit products, but this experience really sucks considering my expectations for this product. If anyone from the company would like to reach out, I would be happy to provide more info if there is a deficiency to address.
