Hardcore Hips

These are probably the best hip armour you can buy. The quality is first class. Not cheap, but who wants a false hip!!

Hope I never need to test them

Fits well. Much better than the foam padding you get as standard on Astars stuff ...

Comfy in Alpinestar Challenger leather trouser

Delivery: SBS as always, quick and well packed. Price : reasonably priced as per current market Quality: A-Star cannot be faulted. Feels like a solid piece of armour compared to the ordinary foam that it replaced in the A-Star Challenger suit trouser - Hip section Fit: Perfect fit as expected. They seem similar to D3O armor. If you squeeze its soft and if you punch it feels hard. Surely similar properties if I am not mistaken. It does mould to your body to an extent as claimed by some reviews, but that is a good thing. Feel: Doesn't cause any discomfort. Feels as if it was already part of the suit. Also invokes confidence in the suit. Wore it during a very hot day and didn't seem to change the comfort of the suit compared to when there was only foam. It's perforated well so does breathe. Test: Hope never to ever have to. Confident it will do it's job. Recommendation : 5/5

Super comfy in my bullit SR6 jeans

Excellent fit, full hip coverage and very comfortable, they get more comfy as they warm up and adapt to the contours of your hips. They feel very well made and even come with some cool sleeves. If you squeeze them hard with your fingers it acts like memory foam but way more dense. I ordered large and they still fit well in my jeans hip pocket. It's nice knowing that you have that extra protection in a spill. I'm happy I ordered these :)

Questions and Answers

Questions and Answers

  • How do I know which size to purchase?

    March 9, 2017

    Small will fit pants up to 32 inch waist and Large for anything over.

  • This may be a silly question, as I am new to this; does this item come as a pair? If not, do they work as a pair, or a single piece? If the former, are they sided left and right, or are they universal for either side? I would want it/them for the Alpinestars Andes Drystar trousers. Thanks in advance for your advice.

    February 20, 2017

    The hip protectors are sold as a pair, and are handed - one would be left and one would be right.
