I like the versatility of wearing bib shorts and adding leg warmers when needed. These stow perfectly in your jersey pocket and stay in place when wearing them although, you need to give your knee a little room by allowing a little slack from just below to above the knee. If you wear them to tightly, they sometimes begin to work down from the top. You can wear them under or over your shorts as the top looks good and retains shape. I recommend hand wash in cold water and I use Woolite Detergent sparingly. Do not ring and hang gently by draping or on top of a towel to dry. Be careful with zippers. I recommend removing your bike shoes while donning and doffing and these will last a long time. I've had a few different Castelli Leg Warmers over the years and this one seems a bit sturdier. Still haven't figured out how to find both conveniently though as they are kinda like sock pairs. Lol. ### ⭐⭐⭐⭐ A bit tight *by C***R on March 5, 2023* Warmers are a great design but run small. Elastic band tight and tends to run down the leg after twenty minutes ### ⭐⭐⭐ Too Short! *by S***B on December 18, 2021* Nice leg warmers but much too short. Size large are 26". Previous Castelli leg warmers size large are 30". ## Frequently Bought Together - castelli Thermoflex 2 Legwarmer - Castelli Unisex UPF 50+ Light Arm Sleeves | Men’s & Women’s UPF 50 Breathable Sleeve for Cycling, Road Biking & Gravel Riding - Castelli Unisex UPF 50+ Light Arm Sleeves | Men’s & Women’s UPF 50 Breathable Sleeve for Cycling, Road Biking & Gravel Riding - Black - X-Large --- ## 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/172449871-thermoflex-2-leg-warmer](https://www.desertcart.co.za/products/172449871-thermoflex-2-leg-warmer) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-05-01*
