They also offer protection to your lenses in transit and storage. 【Easy to Remove / Add】Place the rainguard cover on the Ocular Lenses outer tubes to protect your lenses. You can conveniently attach to your binocular strap to keep within easy reach. 【Design】The high quality One piece flexible cover stretches for a tight fit.

The 42-43 mm size fits my Swarovski 32x10 NL Pure binoculars like it was made for them. (The outside diameter of the Swarovski eyepieces measured 42mm.) It is made of a soft rubber which is slightly grippy and conforms nicely to the eyepieces, so it's easy to put on and take off but won't fall off. I prefer it to the one that came with the binoculars which is bulkier and more rigid, and somewhat difficult to remove quickly. Review: Perfect fit - Perfect fit for our Sig Sauer binos. They came with two separate caps. Who wants to deal with that? Almost always when I’m using the binoculars at home it a rush to see something before it’s too late. This set of connected lens caps is perfect. I don’t have to worry about dropping them, I installed a tether to the loop provided. They’re tight enough to stay on but loose enough that removing is easy. ## Features - 【Measuring】Please measure the Outside diameter of the Ocular Lens outer tube's diameter to get accurate sizing, if the diameter is between 40.7-42mm, it will fit perfect.

It works but I'm not overly impressed with the left side binocular strap holder. It's an open ended holder for that side strap, instead of being closed-ended like the other side. The design for that reason is not great, but I will say that for being China made, the rubber seems to be of decent quality, though I haven't used it yet in the field. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/525324116-40-7-42mm-binocular-rainguard-eyepiece-eyecup-cover-dustguard-eye](https://www.desertcart.co.za/products/525324116-40-7-42mm-binocular-rainguard-eyepiece-eyecup-cover-dustguard-eye) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-11*
