I’ve had a number of BTR products over the last few years - each product was built to last, functional and always at a great price. This review is for the Large Waterproof Hi-Vis rucksack cover. It almost entirely envelopes my rucksack meaning that when I reach my destination, whatever is in my bag is dry. Easy Velcro fastening means the cover Can be adjusted to fit the bag (in my case, a 32 litre daypack). It’s very hi-vis... Saturn Yellow (as used by emergency services etc) and with reflective strips and a handy cargo pocket on the rear. What’s not to like? It does exactly what it says in the description... Waterproof, High Visibility, Large, Adjustable, Functional. BTR customer service and delivery times can’t be beaten. Helpful and knowledgeable staff and rapid delivery too. Can’t fault them. Don’t hesitate to buy BTR products, they’re spot on!

BTR Large Yellow Hi Viz Rucksack Cover

I bought this pretty large cover as sometimes I have a fair bit of gear to take to work e,g, a shower towel which can bulk out my rucksack a bit. This cover is splendid and fits perfectly over a larger load. The fastening are secure keep the rain off too. A great piece of kit from BTR
