Koolpak Luxury Reusable Hot & Cold Gel Pack Large (12 x 29cm) with Non-Woven Sleeve - Twin Set

I have a pretty bad case of shin splints with terrible pain just to stay on my legs so this pack is an everyday relief for some time now. I use them every day, couple of times and they help a lot. I was struggling with actual ice before but it was too hard, but these packs mold around my shin and they are effective for a long time as well. They cool down pretty fast, but I usually leave them in the freezer for an hour or two before I use them. If I forget it in the freezer for a couple of hours, it becomes rigid, but transforms back quickly. All in all, really good and effective. I hope I can use them for a long time

I have bought four now. I have shingle nerve damage to my torso so I will wrap one of these I a towel and lean on it when the fireey nerve pain starts and it calms it down. Lasts for hours. Good product.

Two pack is ideal for hot and ice treatment of injuries. Decent size packs mean that I could cover the whole calf area easily. If you need to wrap around smaller areas you may need to pre-shape when freezing.Frozen pack lasts at least 30 minutes but heat pack is probably only 20 minutes, so don't buy if you're planning to use as hot water bottle! Those timings are ideal for injury treatments. I microwave on full power for 2 minutes.The covers are also very good to prevent burns and do protect the skin well - far easier than towels.Using twice a day I've not noticed any drop in performance or issues with seams.Good value.

These are some fab hot and cold packs, I've tried other ones from supermarkets that have beads inside but they are a little useless when it comes to staying cold, they also tend to be scented which is not what you want when you need a cold pack! This is great when you or your family have a fever, a headache, an injury which needs icing, etc, or a pain which needs heat to help ease it.The pack freezes very quickly in around an hour or two, it then stays cold for at least 2-3 hours, maybe longer. It does come out of the freezer very hard and not flexible, but moving it around with your hands quickly makes it break up a little and becomes flexible, allowing you to mould it round the body part that requires the cold. It also heats up very quickly and stays hot for a considerable amount of time, however I bought these more as cold packs and therefore know more about using them cold.The sleeve is useful as this means the pack is not directly on your skin, however it reality it is still extremely cold with the sleeve. We have been wrapping it in an old shirt, over the sleeve, when first used to take some of the cold away. After about half an hour, it's fine with just the sleeve. Maybe we have a super cold freezer though!I definitely recommend this and think I will be buying another couple when I have the funds, I can then have two in the freezer at all times and two ready to be heated. I really do recommend these and they are a great price, considering that you get two packs.

used after operations really helped

These Koolpaks are great for treating so many issues.I recently tripped whilst running and sprained my ankle. It's quite badly bruised so I used our existing cool packs (the rigid blue plastic kind) but could not really get contact where I needed it because of my ankle bone. My parents recommended these Koolpaks and they have not disappointed.Some of the benefits of these Koolpak's:- The packs are made of a soft coated nylon which allows the pack to be moulded around injuries unlike the hard plastic packs.- Comes with a thin non-woven sleeve allowing you to use without wrapping in a cloth and providing closer contact.- Great value for money - 2 Koolpaks and sleeves for a few quid each!- Can be used as a heatpak in the microwave (instructions listed on the back of the Koolpaks).I have seen some other reviews who state the sleeve does not look genuine. The sleeves I received look like those on the official Koolpak website so no issues here!Personally I think this is a great product at a very good price and have no issues recommended it!

Very unwieldy when frozen but it is ok once melting a little

These are great for isolating specific injuries or areas of soreness. You can leave them in the provided sleeves for a super-freeze, which I like, or double it up with a T-shirt or piece of clothing. I use them over my shoulders to help treat reoccurring rotator cuff tendonitis and also on the elbow joint for tennis elbow. If I have been to the gym in the evening I sometimes lie one down the length of the quads on each leg in order to help cool them down before bed - I sometimes have trouble sleeping if my legs are feeling well worn and I'll get restless legs and start clashing them together like seal flippers in the night. These help a lot with that, as well as a cool shower.They take a small amount of melting when you get them out of the freezer initially as you won't be able to bend them properly when fully frozen. I would say, BE CAREFUL not to force them to bend too much when they're still frozen, this can cause them to split and you'll be covered in bloody embryonic alien gunk which is no doubt harmful. I've previously had the larger square koolpaks which felt great to really cool down the whole shoulder area but often felt wasted as they were harder to contour to the body - once slightly melted though it felt like a big friendly ice cold jellyfish.I tend to lay on my side or back and weigh them down with a water bottle to make them more effective. All in all - many, many times more effective than those useless refillable ice bladder type things. Would recommend.
