Although the design is so simple, the versatility and durability of this SWAZI® Original is absolutely awesome. The sleeves are cut to bellow, allowing air to circulate and keep you cool on warm days. On cold days the 280gsm quality polar fleece is great as a superb first layer or wear it in your bag on a frosty night. If you don't own a Bushman's Tee and your mate does, steal it from him! Mates are much easier to replace!
