Traffic whose session secrets are established solely through quantum-vulnerable public-key mechanisms can be recorded today and stored until it becomes readable. An adversary does not need to break the key establishment now, only to keep the ciphertext and the handshake until a machine exists that can recover the session secret from the recorded key exchange. Exposure depends on how long your data must stay secret, not on how strong the key looks today.

Our suppliers provide these measurements. Note that product dimensions may differ by up to 2 inches (5 cm).

Customers in the US should consider selecting one size larger as the EU sizes from this supplier tend to be smaller compared to US sizing.

A useful tip! Compare the measurements of one of your own items at home with those listed in this guide to ensure the best fit.

A Length

Start the tape at the top of the tee right next to the collar (Highest Point Shoulder) and extend it to the bottom edge of the shirt.

B Width

Begin measuring from the seam right under one sleeve and extend the tape across to the seam under the opposite sleeve.

C Sleeve length

Start the tape at the top of the set-in sleeve and measure down to the sleeve's hem.
