TUFF Double Ply Knee Sleeves are a dual-ply support which are designed to compress, support and provide warmth to your knee joints when training. These are perfect for strongman training, weightlifting, powerlifting and any exercise where you want support to your knees.

Our sleeves are made from an optimum blend of material that will stretch and form to your elbow joints and follow the contours of your arms. The material is double-ply and thinner (compared to our Neoprene Sleeves) which provides an extremely comfortable snug fit. Due to the fact they are thinner, these will allow for a natural feel in your range of motion when training.

Using a unique rubber non slip strip also around the upper edge of the sleeve, we found a way to prevent these from slipping during periods of constant use, especially for events like the farmers, yoke carry and atlas stone in competitive strongman.

Delivery times vary by destination and customs clearance processes.
Recipients are responsible for any local import duties, taxes, or customs charges.
We cannot influence or expedite customs procedures in destination countries.

4. Delivery Confirmation, Risk & Transfer of Responsibility

(a) Signature Required

A signature will be obtained at the point of delivery.
Until a signed handover occurs, the parcel remains at NI Supplements’ risk.
Once signed for by you or a nominated recipient, delivery is complete and responsibility transfers to you.

(b) No Signature Required / Authority to Leave

By selecting “No Signature Required” or authorising an unattended delivery / safe place, you:

Expressly instruct the courier to deliver the parcel to your address or nominated safe place without obtaining a signature.
Acknowledge that the courier’s photo and GPS confirmation constitute full proof of delivery.
Accept that once such confirmation is recorded, the order is deemed successfully delivered, and
Agree that risk of loss, theft or damage passes to you immediately upon that confirmation.

Accordingly, NI Supplements’ delivery obligation is fully discharged once the courier records a delivered scan with accompanying GPS/photo evidence.

If you are concerned about parcel security at your address, please select “Signature Required” at checkout. This is recommended for high-value orders or where the delivery location is unattended or visible from a public street.

5. Non-Delivery Claims

All non-delivery reports are investigated directly with the courier.
Where the courier provides proof of delivery (signature, photo or GPS record) matching the supplied address, the order is considered fulfilled and is not eligible for replacement or refund under this policy.
Where the courier confirms no delivery, we will either resend or refund the order promptly.

6. Failed Delivery, Refusals & Returns to Sender

If a parcel is returned due to customer error (e.g., incorrect address, failure to collect, or refusal of delivery), we may either:
- Resend it after payment of a re-shipping fee; or
- Refund the product value less the original outbound shipping cost.
Where the error or delay was caused by NI Supplements or our courier, we will resend at our expense.

7. Same-Day Dispatch Guarantee (Express Orders)

Guaranteed for orders placed before 1 p.m. (Monday–Saturday).
Couriers may experience exceptional delays beyond our control; such events do not invalidate the guarantee for dispatch timing.

8. Working Days Definition

“Working Days” means Monday to Saturday, excluding UK Bank Holidays. Orders placed after 1 p.m. on a Saturday or on a Bank Holiday are processed on the next working day.

9. Evidence & Investigation

We maintain courier records, including time-stamped tracking data, GPS coordinates and photographic delivery evidence, for audit and anti-fraud purposes. Customers alleging non-receipt after confirmed delivery may be asked to provide a police crime reference number. We reserve the right to cooperate with carriers and authorities in any fraud investigation.
