Works as advertised
Cap Strap arrived on time and works as advertised. It's very well-made and easy to put on and remove, meaning that I can take it off before tossing the bottle in the dishwasher. Highly recommend.

Good product, could be a bit cheaper.
Great product, metal ring which is nice, webbing could be of better quality. Maybe tubular webbing. After tax and shipping it’s close to $30 which is a bit much for the product….to me it’s worth about $15 total including tax and shipping.

Great
I had a lost shipment that was not TAHR's fault. Sent an email and they resent the order. Product fits perfectly on regular Nalgine bottles and is a quality product. Would recommend and would buy again.
