1. Light with good protection.
2. Easy to pack.
3. Blue straps perished and failed after around 1 year. Luckily, the B&w dealer in Thailand replaced all straps with black straps. The new straps have only one full length strap which makes packing easier. Fix cost about 100 us ( I didn't buy from them)
4. He said blue straps have frequent failures, so only buy black one-cross strapped versions
