Elevation Training Mask 2.0 - for Endurance - Increase Your Sports Performance, Endurance, Weight Lifting, Workout, Running Altitude Mask, Fitness Running, Manufactured in USA

Le carton un peu cabosser mais ce n'est qu'un détail (on ne juge pas un livre par son apparence) je l'ai reçu 2 jours en avance ce qui est surprenant ma foie et bon. Le masque est bien, je ne l'ai pas encore essayer pour mes pratiques sportive mais j'ai confiance en lui. Le masque est en bon état et c'est normal. Pour le titre le colis est trop parfait c'est pour ça que j'ai mis ce titre et c'est aussi pour ça que j'ai été largué. PS: c'est une blague

this is with out dought a brilliant piece of kit iv been do 1 mile runs to 5 mile runs with this mask and when it comes to running with out the mask you can really tell that your fitness has been improved, the mask comes in three sizes so its very easy to pick with size you need, fits round the face very well, the selction of elevation is very easy to understand and select, over all i think its amazoning, hahah get the pun, and would recomend it to anyone who wants to train the cardio spectrum

It’s so good for run, incredible the way to bring resistance.

Pedí 2 training masks por error, hasta ahi es mi error, después de 2 dias, me llega mi pedido, el problema fue que solamente llego 1, en ese momento decido mandarle mensaje al distribuidor, y hasta la fecha le he mandado 3 mensajes para ver si se puede hacer algo, y no me ha contestado. fuera de eso la mascara la recomiendo mucho, ojo con los errores de pedido.

Really good for mental training more than anything.its not the same as high altitude training but it does make training a lot harder,you really have to concentrate on your breathing.highly recommended,I would have put 5 stars but to be honest the quality doesn't match the price tagged.i was actually quite shocked when I saw the material it was made from.but it is patented so theY can sell it for what they like I suppose
