Sea to Summit Sleeping Bag Liner AREACTOR Reactor Thermolite

Lightweight and rolls up tiny, keeps your sleeping bag clean and allows you to turn in the night without your bag turning with you. Easily washed and dries quickly- although watch it if you are drying over a fire or stove as the material melts easily. Nice feature of a light coloured band round the to so you can see how to get in even in low light and the drawstring does increase the warmth in icy conditions (it opens with a pull so no danger of strangling yourself with it). Very good.

I crossed the Atlantic Ocean on a small sailing boat using this. It's perfect for warm environments and even when it's a bit chilly, it offers some protection and something to get cosy inside of. Feels lovely and soft. Rolls up easily and stuffs back into it's bag fairly quickly too - important when you're a yacht racer :) Washes easily. Useful if you want to sleep and protect yourself from lying straight onto a surface with no sheet. For colder environments you'd need a blanket or much something much thick. Anything under 15 degrees C and you'd be cold I think.

This is a good enough sleeping bag liner that does the job. It can add a few degrees to a summer bag I use it with my 7 degree comfort limit bag as it extends its range a bit. It's comfy and soft, and it helps keep your sleeping bag clean. Once I camped out in a heatwave and used just this and it was great . I like sea to summit products, and lots of my sleep setup stuff is from them. The only negative is that I think this is a little pricey for a thin fabric sack

Lightweight, compact and added extra warmth to my summer sleeping bag. I love my summer sleeping bag due to it's small size and weight, but often find myself a little chilly in it. Started using this and not only did the chills disappear but it's also so comfy that I may start using it with my winter bag too!

This was great for climbing Mt. Kilimanjaro, my group got ahead of the schedule and ended up spending 2 nights at Barafu Camp (approx. 4500m) to allow us more time to acclimatise for the summit. Our tent wasn't put up very well and the moisture that leaked through turned to ice (so I can assure you it was cold!) but this liner, in combination with my Rab Ascent 700, kept me warm. Before buying I couldn't decide whether to get the liner or upgrade my sleeping bag, I decided to gamble and go for the cheaper option and it paid off. It's soft, light weight, compacts down well into its own little pouch and you could probably sleep in it on its own in warmer climates.

After several holidays in this country and feeling cold at night (even in July/August!!) decided to buy the AREACTOR Reactor Thermolite Liner. One of the best decisions I have made. I have just been on a very wet!!!! two week cycle/camp holiday in South of England. This liner took the edge off the night time chill and I was not cold once. It also fitted easily into my sleeping bag and did not slip around and get tangled during the night. Trying to keep equipment dry was impossible with the weather we had so it was with relief, when we got a few hours of dry weather, that the liner dried out quickly. It packs away easily into its own pouch but I found it stayed so well inside the sleeping bag, that it was just as easy to leave it inside. It has a lovely soft feel to it and I would highly recommend this liner for anyone who feels chilly at night while camping.

I bought this liner to go inside a Alpkit Skyehigh 1000 for a trip up Kilimanjaro in September. Temperatures went down to -15C and I was as warm as toast. I didn't need to use the liner until the last couple of nights when the temperatures were well below zero. The bag was advertised as being good to -12C, and it was but the liner just gave me an extra bit of warmth and comfort. It packs up very small inside the stuf sack and weighs next to nothing, so doesn't ake up any extra space in your rucksack. I'd recommend this product to prospective purchasers.

I use this with a 2/3 season sleeping bag and it is very effective! It's enabled me to spend the night in negative temperatures. I particularly like the fact that it enables me to wash the sleeping bag less often (drying it is difficult as I can't use a tumble dryer). It is also large enough for me to pull it over my head (I'm 5 foot 7/1.71 meter tall). It dries really quickly too and I've been able to leave it in the tumble dryer for a short while to accelerate drying. Lastly it is very small once packed and extremely lightweight. Expensive but worth its price.

l'ho provato ma a temperature più alte di quanto previsto, ma tiene più caldo di quanto si possa pensare. è molto leggero e appare sottilissimo, ma la fibra cava con cui è fatto lo rende molto performante. Sea To Summit è una certezza, il prodotto si paga, ma la qualità è eccellente. oltretutto è molto morbido, non dà fastidio sulla pelle e non irrita le parti intime, cosa molto importante per me che dormo nudo

Hafif, yer kaplamıyor ve işini görecek gibi duruyor. Sea To Summit kalitesi..

Took this on my first backpacking trip to Death Valley in January (3 nights). It was colder than expected. The second night so cold our water froze. This liner not only made my sleeping bag cozy but added every bit of extra warmth advertised and some. Well worth the extra money and space in the pack. This will be a staple piece of my sleeping gear even in warmer weather - it adds that extra bit of comfort and to any sleeping bag. I also love the lining between dirty, several days into the trip body and the sleeping bag. It’s super easy to toss the liner in the wash and keeps the sleeping bag from having to be sent out for cleaning after every trip.

Très compact pour le transport dans un sac à dos. Déjà utilisé à plusieurs reprises en bivouac en tente. Même s’il est difficile de vérifier le confort thermique, couplé à un bon duvet ce drap est agréable, enveloppant et protège le duvet. Mes 1m86 y rentre sans problème, il est possible de s’envelopper quasi complètement en resserrant la sortie (à l’instar des duvets type momie).

シュラフの補助的役割になる物を探していて色々検討してこちらに決めました。 まず窮屈でない物、そしてザックに入れるため薄くて軽い物、コンパクトになることが条件で実際届いた物を見て全て当てはまっていたので満足しています。 私はマミー型、封筒型シュラフの窮屈さが苦手で今はキルト型のシュラフを使っていますが、もし寒かった時のためにインナーシュラフにするか、シュラフカバーで対応するか、もしくはキルト型の自由さを活かすなら上からタイベックシートなどを被せるだけにするか悩み、窮屈かもしれないというリスクはあるものの信頼しているシートゥサミットにしました。中に入ってみたら窮屈さなど全くなく、生地が横にビヨンビヨン伸びまくって問題なし。中であぐらもかける。 生地はさらさらで手触り良し、かなり薄くて透けるほどですが中に入れば明らかに保温されているのが実感できます。 値段が高いのがネックではありますがダウンシュラフの汚れを減らすことにも繋がるし、家にいる時に寒ければ足だけ入るとか肩にかけるとか色々使い道があって気軽に洗濯もできるので買って良かったと思います。
