Abrasion-resistant and 100% light-blocking. Lightweight folding umbrella made with CORDURA® fabric
This lightweight model combines abrasion-resistant "CORDURA® fabric" with 100% light-blocking and heat-shielding functions. By combining high-performance fabric with a lightweight frame designed for portability, this all-weather umbrella smartly handles everything from intense sunlight to sudden rain.
【Three Key Features】
-
100% light-blocking and heat-shielding to block heat rays
Features a high-performance fabric that blocks 100% of visible light. It physically blocks sunlight, creating a cool space and proving highly effective in preventing heatstroke during severe summer conditions. -
Fabric strength achieved by CORDURA® fabric
Uses CORDURA® fabric, which is resistant to friction. The fabric is less likely to be damaged even in demanding use cases, providing high reliability for long-term use. -
Lightweight and strong frame structure, cleared 15m/s wind speed test
While pursuing lightness, it has cleared wind resistance tests at 15m/s. By combining carefully selected materials such as carbon, it provides stable usability and robustness even in strong winds.
【Commitment to Function and Quality】
-
PFOA-free specifications and a generously sized storage bag for easy packing
Uses environmentally friendly PFOA-free agents. While maintaining sufficient water repellency for daily use, the storage bag is designed to be roomy, making it easy to put the umbrella in and take it out. -
Tough and lightweight design that withstands harsh environments
We pursued a lightness and robustness that allows for daily carrying without burden. The synergistic effect of the strong fabric and wind-resistant frame ensures that high light-blocking and heat-shielding performance is maintained over the long term.

To the ultimate in lightness and durability. The chemical reaction brought about by CORDURA® and HEATBLOCK.
The material we arrived at in pursuit of ideal "toughness"
Since its establishment, Amvel has consistently pursued the value of "lightness and durability." To realize this concept at an even higher level, we focused on CORDURA® fabric. With strength to withstand harsh environments and used in outdoor gear, this material perfectly matched the ideal umbrella we envisioned. However, incorporating this fabric into an umbrella product presented significant challenges.
Overcoming nylon's "weakness" with technology
Nylon, the main material of CORDURA®, possesses excellent properties for an umbrella, such as high hydrophobicity and water resistance. On the other hand, it had a major drawback: it was "prone to stretching." If the fabric stretches and shrinks, it can interfere with the opening and closing mechanism. How could we minimize this disadvantage? Our solution was to bond a unique light-blocking film to the back of the fabric. By integrating the light-blocking film, we physically suppressed the fabric's stretching and dramatically improved the umbrella's stability.
The ultimate toughness, imbued with light and heat shielding
This ingenious solution allowed us to leverage the inherent toughness of CORDURA® while adding the highest level of functionality: 100% light blocking and 100% UV protection. We took advantage of nylon's weakness of being prone to stretching and elevated it into a "tough, shape-retaining fabric" through its combination with the film.
A single umbrella that supports you from daily life to adventures
"Reliability as a tool" is the sincerity of our craftsmanship. This CORDURA® series was developed not just as a simple rain or sun umbrella, but as a "tough gear" to support your lifestyle. We want you to use it without hesitation in any situation, from your daily commute to weekend outdoor activities.

Q: It says 100% light-blocking, but does it provide a cool, shady feeling?A: We use "HEATBLOCK" technology, which achieves 100% light-blocking and 100% UV protection, physically blocking sunlight. It also has a high heat-shielding effect, effectively blocking strong sunlight and allowing you to stay cool and comfortable under the umbrella.
Q: What are the benefits of using CORDURA® fabric?A: It is a highly functional material characterized by its exceptional resistance to abrasion, tearing, and scuffing. Its durability, which is also used in bags and outdoor equipment, ensures that the fabric is less prone to damage even with daily carrying and harsh use, allowing you to enjoy it for a long time.
Q: Please tell me the weight and size of this umbrella.A: It weighs approximately 140g, making it very lightweight, and it folds into a slim, portable size. When open, it has a diameter of approximately 90cm (main rib 50cm). While it is slightly smaller as a rain umbrella, it is sufficiently large for a parasol. It is ideal as an everyday umbrella to keep in your bag.

■ 生地の色味・風合いについて
傘生地の生産および製品の特性上、以下の事象が発生いたします。これらは製造工程上避けられないものであり、製品の品質・性能に問題はございません。あらかじめ内容をご理解いただいた上でのご購入をお願い申し上げます。
① 生地ロットによる色の差異
生地ロットの違いにより、同じカラーであっても色味に微妙な差異(色ブレ)が生じる場合がございます。
② パーツごとの個体差
同一ロットの生地を使用している場合でも、裁断箇所の違いにより、傘本体と付属の収納袋とで色の濃淡がわずかに異なる場合がございます。
③ 掲載写真との相違
商品写真はできる限り実物の色に近づけるよう努めておりますが、お客様のご利用環境(モニター設定、スマートフォンの画面輝度等)や、撮影時の照明・自然光の状態により、実際の商品と色味が異なって見える場合がございます。
■ 撥水機能とメンテナンス
撥水加工は永久的なものではありません。ご使用中の摩擦、雨に含まれる不純物、皮脂等の付着により、徐々に効果が低下します。
撥水力が低下すると生地表面が濡れたように見えることがありますが、裏側に浸透していなければ雨漏りではありません。撥水力が弱まった場合は、市販の撥水スプレーでお手入れしていただくことで効果が回復します。
■ 開く前の準備
傘を開く際は、バンドを外して2〜3回軽く振り、生地と骨を十分にほぐしてから開いてください。生地や骨が絡まった状態で無理に開こうとすると、故障・骨折れの直接的な原因となります。
■ 耐風性能に関するご注意
表示の耐風数値は試験設備内での計測値であり、いかなる強風にも耐えられることを保証するものではありません。
突風や多方向からの風を受ける実際の荒天時には、破損や怪我の原因となりますので、無理なご使用はお控えください。風が強いときは、傘を風上に向けて使用してください。
■ 穴あき・劣化の防止
・圧迫禁止:カバンの中で傘が強く圧迫され続けると、フレームと生地が擦れて穴あきやコーティング剥離の原因となります。
・保管:ご使用後は軽く水気を払い、直射日光を避けて陰干ししてください。濡れたままの放置はカビや錆、生地劣化の原因となります。
■ シャフト(中棒)の仕様
折りたたみ傘のシャフトは、スムーズな伸縮操作と、風などの衝撃を逃がすために、あえて接続部分に「あそび(隙間)」を持たせる構造になっています。
新品の状態でも多少の揺れやぐらつきが感じられる場合がありますが、破損を防ぐための正常な仕様(良品)ですので、安心してお使いください。
■ 機能性検査結果(生地)
当社製品における数値は、第三者検査機関による生地の検査結果です。
・遮光率:JIS L 1055 A法
・紫外線遮蔽率:JIS L 1925
・可視光線カット率:分光光度計法 / 400-800nm
・近赤外線カット率:分光光度計法 / 800-2600nm
※上記は試料(生地)に対する検査結果であり、製品全体の性能を保証するものではありません。縫製部(ミシン目)からの微量の光漏れや、地面からの照り返しにより内側に光が届くことがあります。
■ 開封時のにおいについて
開封直後、遮光生地のコーティング(PU)特有のにおいがする場合がありますが、不良ではありません。
気になる場合は、傘を開いて通気性の良い場所で数時間陰干ししていただくと軽減されます。
