Whether you’re an avid backpacker/camper or a first-timer, you want to be able to sleep in comfort no matter where you are. This sleeping bag isn’t just made for warmth and comfort but it’s also ideal for those that are worried about weight.

If you’re looking for a sleeping bag which won’t add bulk and extra pounds to your back, then you’ll love the feather-weight design of the Sea to Summit Spark. So, whether you’re backpacking during the spring, summer, fall or winter, this sleeping bag is built to support you throughout the year.

You no longer have to search for that perfect sleeping bag because it’s right here in front of you.

Sea to Summit Spark SPII Ultra-Dry Down Sleeping Bag

One of the main features that the Sea to Summit SPII Ultra-Dry down sleeping bag brings to the table is the fact that it only weighs one pound. This makes the bag great for backpackers and it can also easily be carried around for longer distances without having to cause much fatigue.

The sleeping bag is not quite the same as many of the other sleeping bags and it does feature some of the non-essential features that will make the bag more custom to you. The 2° temperature rating directly indicates to us that the sleeping bag falls in the winter bags category and since it is made from down insulation, the sleeping bag will ensure that you are kept warm in some of the coldest camping conditions aside from outside in the snow.

Sea to Summit Sleeping Bag review

This bag is constructed from 10D nylon materials, which also adds to the overall durability of the bag and since it has been treated with a water resistant substance, the sleeping bag will keep you dry in the rain as well. However, eventually, water will start seeping through the zipper areas after prolonged exposure and this is the one fatal flaw in this bag.

The down materials are great for insulation, but once they do get wet, they will stay wet for longer and become soggy, thus rendering the sleeping bag useless for the time being. We recommend that you try and keep the bag as far away from water as possible to ensure that you can have a dry sleeping experience.

Now that you understand some of the basic features of this sleeping bag, let’s have a look at some of the essential features and how they could possibly benefit you.

Packaging

Since the sleeping bag only weighs in at approximately one pound, the bag will definitely be easy to carry along. The manufacturers kept in mind that minimalists always love to carry along as little products as possible and they also like to save a lot of space. This sleeping bag comes with a sil-nylon compression sack which is extremely small.

So, while rolling up your sleeping bag, you’ll want to pack it as tightly as possible. After it’s completely packed, it’s smaller than a football, so you can fit it in your backpack with no problems. With this bag, you will be able to venture without feeling like you’re carrying your home on your back.

Design and durability

The design of the Spark sleeping bag is very simplistic and minimalist, which is what you should be looking for if you’re concerned about weight. It’s designed to be a slim fit, with lightweight fabric and 850+ fill down.

There’s a contoured hood with a drawcord, a large zipper with a no-snag fabric that’ll prevent you from having any zipper issues. A nice feature is that it’s anti-microbial and anti-bacterial.  Because weight was the main focus of the Spark, there aren’t any special features which add to the design. It’s supposed to be lightweight and warm – that’s it.

In terms of durability, the 15-denier Nylon lining give the sleeping bag its durability without having to sacrifice its lightweight feature. So, it’s a perfect blend of both strength, warmth and minimalist design.

Warmth

The bag features down insulation incorporated in the construction and since it is really lightweight, people might be skeptical about the warmth that it provides. The European duck down has been widely known for the great insulation that it offers the user to ensure that they stay warm. The bag has a cloud-like feel on the inside and this should really help to promote comfort as well.

The sleeping bag can also fully zip up and the added hood will not only provide great comfort for your head but also some excellent heat retention. If you have a beanie to add to your sleeping attire, the bag will keep you warm in even colder conditions.

Comfort

The primary high loft downs used in the construction of the bag will make this bag extremely comfortable. It also features a slim design, which means that you might be giving up a little in terms of spaciousness in the bag, but you will gain a lot from having better insulation.

This bag is also extremely durable on the outside and it has been made from 10 denier nylon materials. The materials will also add a little extra padding to the bag from the ground and you should not have a lot of problems mirroring the good night’s rest that you are used to at home.

Versatility

Of course, because it’s a lightweight sleeping bag there will be some features that will be taken away. Because it’s lightweight, the Spark SPII isn’t as versatile as it’s competitors. The minimalist design prevents the sleeping bag from being able to endure extreme weather conditions.

So, if you’re planning on using it during snow storms and windy conditions, do not expect it to withstand those conditions. In that case, you’ll need a sleeping bag that’s designed for harsh weather conditions which most likely means it’ll be heavier. So, if weight is really an issue for you, know that you’ll have to sacrifice some feature.

However, if you’ll be camping or backpacking outside the shoulder seasons, then this sleeping bag will provide you just the right amount of warmth and comfort.

Value for Money & Guarantee

This sleeping bag is approximately $379, so if you’re backpacking on a budget, this may be a little out of your price range. However, for the quality of the sleeping bag and the lightweight features, it’s well worth the investment. This sleeping bag will be by your side for years to come.

Sea to Summit Sleeping Bag value

Any Sea to Summit product, including the Spark SP II is provided a warranty against defects in materials and workmanship for the intended life of the product.  So, you’re given your basic limited warranty which most companies offer to their clients.

Overall, for the quality of the product, the Sea to Summit Spark SP II is reasonable in price. You won’t be able to find another durable lightweight sleeping bag for anything less expensive.

Unique features

The unique feature about the Spark SPII is the weight. In all other factors, the sleeping bag’s feature has been cut dramatically in order to give users the lightweight design.  Its lack of features is its biggest feature.

The Sea to Summit Traveler TR1 Sleeping Bag is another sleeping bag from the Sea to Summit company which is a good option if you’re unable to purchase the Spark II.

It’s made with high-loft 750-fill duck down which gives you warmth while the UltraDry Down glaze retains 60% more loft and absorbs 30% less moisture than untreated down. This greatly effects the weight of your sleeping during the wetter days.

What’s great about the Traveler TR1 is that you can connect it to another Traveler TR1 if you’ll be sleeping with another person.
