### ⭐⭐⭐⭐⭐ 







  
  
    Great cup. Bit small. Consider the Sea to Summit X-mug?
  

*by S***R on Reviewed in the United Kingdom on 24 June 2017*

Really good cup ... does exactly what it says. Yes, it smells a bit of silicone, but I don't mind that (it does fade). I have used it and it works fine. Be advised this is the smaller cup... there is also a bigger X-mug version which I did not get. Weight is important to me so I went for the cup, but when traveling I get super-thirsty so I changed my mind and think I should have gone bigger (the weight difference is just a few grams).So, my bad. I kind of wish I'd got the X-mug-version for versatility, as this is quite a small cup (it holds about the same amount of liquid as a small glass or older type tea-cup) ☕️ . If you only want a little cup ... this is great. Packs small, and light, and hard to loose... being bright :)

    X-Cup is a nice size
  

*by P***2 on Reviewed in the United Kingdom on 5 February 2020*

So good I had to buy a second one for a family trip. I bought this Sea to Summit X-Cup in lime green and I've been very happy with it.It compacts down to such a small size which is what initially sold me. But better still there is no after taste of the cup what so ever.I even did a taste test with my family and we was all surprised by this. Now its not as big as X-Mug ( which I also own) and to be honest thats a good thing as its easier to hold. It's suits some people in my family better.My only complaint is the price difference between colours. Other than that. Its 5 stars all round.

### ⭐⭐⭐⭐⭐ 







  
  
    It's a collapsible cup.
  

*by A***R on Reviewed in the United Kingdom on 4 August 2019*

Does what the description suggests :-)Unlike the salomon cup this has a rigid black outer rim which holds it firmly in shape when drinking or placing it on a flat surface. I actually got this to use as a small water bowl when out running with the dog, which it works well as, (you have to hold it in your hand as the dog drinks though. Folds to a 15mm thuck x 95mm diameter disc and fits easily in a running pack/bumbag/pocket.
