Throughout January New Era are giving away official NBA gym sacks with every order made online.
The gym sacks available are shown on the main page and they randomly select one for you. They're pretty cool too, I assumed they were made from the plastic gym sacks are normally made from but these are 100% polyester (still plastic but feels different) soft and that, it is in a style of a basketball t-shirt and it even has a players name on the back.
Although I don't like basketball but it will do for when I go to the gym.
New Era is an online baseball cap store selling a huge range of caps. They mainly specialise in fitted caps, which are not adjustable so you will need to buy the correct size cap, but they do have a small range of adjustables too.
Delivery is £5.50 per order and it states 7-10 days delivery, mine actually came next day.
