Question: are the helmets in kids or adults?
Document: I choose the X-Large size but its hard to fit in. The quality is okay though, but it is really small. I tried a helmet in the snowboarding shop in the size of X-Large and it fits very well. I think this helmet is for kids, NOT for adults.
First off, I ordered the Matt Black version of this helmet. The company did not list whether this helmet is for adults or kids so that is the first problem. I took a chance and assumed it was adult, and just in case ordered the "Large" size. Helmet finally arrives after a long time shipping, looks the part for sure.
First off, I agree with a previous review that stated advertising could be better and the sizes run small. This company DOES make helmets for adults, but the sizing is all off. I am fortunate to live where the company is based, so I was able to go to their warehouse and try them on before I purchased. Glad I did. All of the other brands I tried on, I fit into a medium (my head measures 57cm).
I bought these after two of my 3 kids wiped out and complained of headache. No more problems. I can also see them from the chair lifts with this cool skull on top of the helmets.
after growing up without having to wear helmets for everything, i was reluctant to buy one for skiing and snowboarding. However, with my kids ready to go to the top of the mountain, i figured i should set a good example and don one if i was going to make them wear one. This helmet is great! the chin strap chafe guard is a great feature.
Bought two of these helmets from Australia(had them sent to Australia) for the coming ski season of 2011. I was a little dubious as the price was so good. However when they arrived I was very impressed(and a little relieved! )at the quality. And the sizes I ordered were correct sizing for the measurements suggested.Lucky Bums Kids Ski & Snowboard Helmet
I think these might be kids helmets after all.Update: I have been to the luckybums website and the head-circumfrence sizes they list are as follows: Adult/Youth Small (54-55cm [21.5"]), Medium (56-58cm [22"-23"]), Large (59-60cm [23"-23.5"]), XL (61cm [24"]). Hope this helps
I am a 5'9, female adult, and was worried about buying one of these because of all the reviews saying how small they run. Lucky Bums is primarily a kids company, but these helmets ARE adult sizes. I took the advice of others, and sized up. I am usually a small, or a 55-56 helmet size, and got the medium lucky bums helmet. It fits perfectly!
The silver, blue and red colors are very nice (those where the 3 colors we purchased).I tried on the more expensive helmets (approx $100) and there is a difference on how they feel compared to this one. It's like a driving a Kia vs. a BMW.I grew up skiing without helmet and noticed that 99% of the skiers now were wearing helmets. I wore one and glad i did, mainly to set an example for my kids.
very nice ski helmet for protection. It can be adjustable so my 11 years old can fit and also can fit adults.
Answer: yes
